Please help me find the right power amp for my setup.. Adcom GFA-545 II?

[trans am]

Hi, this is my 1st post.
Here's the deal. I bought a Onkyo Refurb TX-8522 last year. It can Handle 100 Watts per channel to 2-channels Stereo Power Output through 8 ohm, 20 Hz-20,000Hz. I have acquired a few speakers since then. I had a set of rti6 and rtia1 and a psw111 powered sub and it all worked fine. I could crank as loud as I want and it receiver would stay on. I sold the rti6 and replaced with lsi7 so now i'm mixing 4ohm and 8ohm speakers and receiver is not having it.

What I want to do is run the psw111 and the RtiA1's off the receiver amp. run a powered amp off the tape output(preout) at 4ohms to drive the lsi7's

I'm looking at Adcom GFA-5400 or GFA-545 II or Parasound HCA-1000A. Any suggestions? I like nice crisp sound im a drummer so I like to hear cymbals. I run my treble knob in the higher end. I listen to lots of synthesizers prog rock stuff. some acid jazz. etc.

Thanks.

btw that PSW-111 is a trojan horse! I can't believe that little thing can produce such perfect tight sounding bass. simply amazing sub.

I have a adcom 545ii in the for sale threads. Perfect condition . I had them pushing some LSI 9 and it pushed them very well.

Why are you running the LSi's and RTi's at the same time?

[trans am]

Why are you running the LSi's and RTi's at the same time?

I like the mid and high range of the rtia1's. What can I say? They sound amazing and I paid $150 for them. I live in a 600sf apartment in new york city. I have the rtia1's set up on each side of my computer monitor.

the layout of my living room goes like this:

one side of the living room I have my computer desk where I run the rtia1's (gaming speakers?) on the other side I have a wall unit that houses all the audio crap and tv..cable box router etc. This side has the lsi7's on each side of my LCD tv. The psw111 is in the farthest corner on the side of the room that has the rtia1's.

SInce the computer desk is offset (left) of the lsi7, the a1's are in the background since they are not really in the main soundstage of my listening area. The lsi7 are the focal point. the a1's paired with the lsi7 make the room produce a wall of sound that is what I wanted to achieve at this price range. I can honestly say out of everyone's apt ive ever been to, nobodys rig sounds anything close to the clarity and dynamic range of my setup. And I only paid around a thousand bucks for everything.

rtia1 $150
psw111$ 300
Lsi7 $400
tx-8522 $200

so back to your question why run rtia1 with lsi7 at the same time? Because they sound fricken amazing together.

[lakesailor]

There were several changes between the Adcom GFA 545 and GFA 545 Mark 11 principally most of those changes were to make the amp more stable driving lower impedance loads so if you are thinking of going with the GFA 545 Mark 11 for running your 4ohm speakers I think you are definitely heading in the right direction.

It’s a nice amp and will drive your speakers very nicely.

thanks everyone. I've narrowed it down to this. Buy leroyjr1's GFA-545 II for $200 plus shipping and wait for it to come to NY or drive an hour to NJ to Affiliated Electronics and buy a like-new GFA-5400 with box/manual and warranty for $280. What would you do?

[heiney9]

run a powered amp off the tape output(preout) at 4ohms to drive the lsi7's


Not sure what you mean here; the tape out like any other "line level" output is NOT the same as a pre-amp out. This won't work to any satisfactory conclusion. You need a reciever with a set of pre-outs.

If you decide to do it anyways GL and after you damage something maybe then you'll get the proper component.

P.s. the "output" and amp do not determine ohms; the load does. So again I have no idea what you are saying here.

i mean I can't run 4ohm and 8ohm speakers on this receiver at the same time It will die. I called onkyo support and they said to use a poweramp with this receiver I simply run off the tape outputs. Now you're telling me I can't?
wtf should I do then? You see the setup I have. how can I get it to work properly to its best potential without having to spend more money? You seem to know what you are talking about. I have absolutely no idea. This is my first time doing this. :) I love this receiver. can't I make this work somehow? here is the back of the receiver. http://i239.photobucket.com/albums/ff94/jackalsmith/tx-8522.jpg

Well, I'm not sure what "terminology" Onkyo support used but there is a huge difference between "tape out" and "pre-out". What model is it? If you look at the back of the reciever and see a section that has removeable jumpers that says "pre amp out" then that will certainly work. But if not, then I don't see how it will work. Line level outputs like the tape loop don't work, and have never been an option.

Damn thats a rad deal. I'm from Minnesota originally. In High School we used to drive to Wisconsin on the weekends to buy fireworks. Can you throw in a sixer of Leines Red? Leroy you see my setup. How would you personally go about all this? (see image in the above post)

[heiney9]

I see the back of your reciever. There are no pre-outs. I'm not going to advise against what Onkyo told you, but that is a very unorthodox way of doing it. I've sold electronics and been in this hobby a lot of years and the option they suggest has never been a viable long term solution, let alone something I would suggest or even recommend.

I'm not even sure it's going to work at all like you want it to or how a "true" pre amp signal should.

Leroy's offer is excellent but it's not going to solve your problem as the "pre amp" he's including will only run the amp which only has (1) speaker terminal, plus you won't be able to use any of the processing from your Onkyo (if you use any of that). By getting Leroy's "package deal" you'll be eliminating the Onlyo and it's functions completely.

crap. so I obviously have to ditch this Onkyo and get a new receiver.

Okay so what is the best bargain 2 channel receiver I can use with a powered sub and has a preout.

[Face]

The only way you could still use your Oinkyo as a pre is if you use the tape outs AND buy a amp with adjustable gain knobs on the front panel. I agree with H9 though, it's not the right way to do it at all.

Your best bet is to sell the Oink and buy a prepro or receiver with preamp out jacks.

can't I just go with leroy and run tx8522 -> rec tape out -> tape in pre-amp -> power amp? sorry for double post IS Marantz SR4320 decent? It seems to meet the criteria

[mmadden28]

Well just to provide a quick option for ya, if yer looking for a new AVR.

I'm about to jump on this deal at Vanns (click here (http://www.vanns.com/shop/servlet/item/features/538649660/pioneer-vsx-90txv)- no affil) for a 2 channel source for my Pool/Patio speakers. Its a full 7.1 AVR, but has preout's if you want to use them to go to an external amp. You only need to use 2 of the channels and it has a sub out-You coudl also ignore any of the other advanced or Video features if not needed. Its only $300 shipped - new and with full warr. You certainly could spend a lot more if you really wanted to. ;)

I asked for feedback from the forum on this AVR--see this thread (http://www.polkaudio.com/forums/showthread.php?t=71508)if interested

[mmadden28]

I love this receiver. can't I make this work somehow?

What about this possibility? Get the Pre and Amp deal from Leroy, run a source (CD, Tuner, iPod) into the preamp. Y-Split the Preamp outs -one set into the existing Onkyo's line inputs for driving the Rti's and sub, and the other set into the 545II for the LSi's.
Maybe??

[trans am]

thanks for the suggestions. What I really want is the successor to the TX-8522. TX-8555 and has exactly what I need and is not expensive onkyo build quality is solid. .......unless I can find a denon DRA-697CI for cheap? damn lsi7 is going to end up costing me more than I paid for them just to use them.

@mmadden28 thanks for the suggestion but I have my PC, record player, ipod/cd, dvd, and cable box connected right now. I need those inputs. Can't I take my chances do the deal with leroy and run off the tape out until I can find a suitable replacement? I can't really afford to do all of this right now but want to enjoy my lsi7's in the meantime.

Because his OnK doesn't have "main in" either and you can't run it that way either So that idea won't work.

The both have their pro’s and con’s. The GFA 5400 is a more modern based mosfet design while the GFA 545 Mark II is old school bi-polar. I have had both and still currently own a few of each in my current collection. For home theatre applications I have found that mosfet based amps are superior; however for music I still prefer the old school.

Given your 4ohm speakers I would likely go with the GFA 545 Mark II. The deal you were offered with the pre-amp added on for an extra $ 85 is a no brainer. That setup will annihilate your current AVR in a big way. Best of luck

[trans am]

got it. Leroy hit me a PM. lets arrange payment.

[anonymouse]

I think you will find that properly powered those LSi7's will sound good enough to discontinue use of the RTi's. Get that pre/pro combo and see what it sounds like.

He is actually getting the pre amp for $50 shipped. Because the amp was $200 plus $30 for shipping, and the pre is going to cost about $20 to ship so he is getting the pre for $35. great deal IMO )

[heiney9]

is basically a done deal. I'm just waiting for his paypal acc info.

Just so you are 100% clear; the Onk and Adcom pre and amp won't integrate with each other. No amp or pre will.

Otherwise great choice and enjoy. I've had an original 545 since 1986. Has performed flawlessly. I have an Adcom integrated as well. Basically a 535 amp section with the SLC 505 passive line stage pre in one package which runs my Monitor 5B's in my office/computer rig. Listening right now and what a"killer" sounding system for the size, output, and $$$.

Leroy, I have a Fedex acc. you can use send it fedex ground do the whole deal for 250.00 and i'll handle the shipping. I'm really strapped for cash and fedex runs off my amex so I can pay it later. Deal?

[trans am]

I'm really strapped for cash and fedex runs off my amex so I can pay it later. Sorry to beat you down I'm embarrassed but you figure if its going to cost you $55.00 to ship. and you want $280 let me pay the shipping and you get $250 so instead of only making $230 you get $250 and I spend less $ upfront. I'm still waiting for PM. I just noticed the back of the GTP500 has 4 usable inputs so this is perfect!

cable box
record player

this is all i really need. I never use the ipod/cd 1/8 in line anyway. And you metioned tuner doesn't work. I can't remember the last time i listened to the radio. such crap on their these days.

I understand its not the best solution, but he was looking for something to help him absolutely keep his Onk in the mix (for some reason). I'm not familiar with the term "Main in"-what is that? :confused:
So he can't run the preamp outputs in to the CD line in?

Nope.

Pre out means the unit is capable of sending a typical "pre amp signal" to an external amp (by passing the pre amplifier section in the unit)

Main in is the opposite meaning you can "plug" the inputs of an external amp into the unit and use the "pre amp" section in the unit (bypassing the internal amp)

These are always "capped" with removable jumpers which work like the jumpers on bi ampable speakers.

The signals that are used for typical line levels (cd, tape, aux, video, etc) don't have anywhere close to the same value as the input or output that the pre in or main out has (they are not compatible). It causes problems and in some cases serious problems as you could overload the amp or send a dangerous "spike" of voltage or high pitched sound to your speakers and damage either or both.

[trans am]

Okay deal is done. I paid him. I can sell the onkyo or give it as a gift and use the preamps 4 inputs for everything else. here's my question since the amp only has 1 stereo terminal, could I run the psw111 of the the amp and daisy chain the lsi7 to the extra terminals on the subwoofer for now? or is that ridiculous? is there a way I can split the terminal on the amp so I can still have a sub?

You can but it will sound like poop as the internal x-over in the sub (if it has one) will "choke" the LSi's.

And no there is no way to "split" the terminal on the amp and you wouldn't want the sub hooked up to the amp, you'd have no control over it's volume except at the sub if it has it's own output adjustment. Every time you'd adjust the volume on the pre you have to manually adjust the sub. Not even sure if the signal coming full out of the amp is compatible going directly to the sub input.

Dude, I can totally appreciate the predicament you are in financially but you can't do the things you want to do with this set-up. It's not designed to operate like a multi-channel HT with sub output. There really is no way to rig it that isn't either a fire hazard or by doing some other damage.

Sorry but that's the truth

[GV#27]

I'm not familiar with the term "Main in"-what is that? :confused:Main in is a direct input to the amp section bypassing all pre amp/processing functions.

So he can't run the preamp outputs in to the CD line in?Yes he could.

The problem with driving an amp from the tape outs is the lack of volume control, its output stays at a fixed constant level.

[trans am]

Okay thanks. I see. I'll run the lsi7 only until I can get my new receiver straightened out. Mod can close this thread if you want. I think I'm all set. :)

Check this out for your powered sub hookup.

This is currently what i'm doing with my bedroom 2-channel setup. Works fine, no problems after a month or so of it running, haven't run into any problems other than a ridiculously overpowered sub vs. my main speakers. Took a lot of tweaking to make it sound balanced.

1) Double up on wires coming out of the reciever's front channels, so i will actually have TWO wires coming out of positive and negative each, for both left and right channels. So... i would have out of the right channel, one pair going to the sub +/-, and one pair going to the right VS-25 +/-. Same for the left. So instead of 4 wires normally coming out of the receiver/preamp outputs, i'll have 8.

2) Run the normal 4 wires directly to the sub, and run wires from those 4 input wires, back out to the left/right VS-25s.



run 2 wires out of a single terminal? are you sure man? This doesn't sound right at all.

I found a new HK-3490 for $280 on buy.com.
This is the latest ver. and has a sub out and the preouts and main in. seems good for the price. I was going to get the Outlaw Audio RR2150 but more money than I can afford right now. I think I'll be able to run everything how I want to on the HK.

Mmaden you're a frickn genius!

I'll get to that in a minute. I bought a HK-3490 replacement for the legendary 3480. It has preout and main in plus a sub out. I thought man I'm all set this is exactly what I need. So today . lee's Adcom kit arrives plus the HK unit. So i'm thinking all day at work about this. Finally I get home and unpack everything. The HK unit is beautiful. The pre and poweramp from lee look like they've never been used. All original packaging and he included very high quality rca cables for the power amp. I take the Onk out and start connecting cables. the plan is use the preout for the amp to drive the lsi 7. then use the speaker 1 terminal for the Rtia1 set and the sub out rca for the psw111. I get the amp hooked up and run the lsi7 off the pre and sound is amazing. then I hook up the rtia1 of speaker 1 terminal on the HK. and no sound. sub out works fine. so what happens is when using the preout on the HK it bypasses the integrated amp in the HK.

Next I run the power amp off the HK tape 2 out. it works like onkyo told me but no way to adjust the voluime for the lsi7. so this is a definite no go.

I was like shoot I paid extra for this and not working to my favor.

next I'm thinking run 2 receivers separately

1 for pc and the other for the tv, record player dvd etc.

run the rtia1 off the onk on my computer desk and run the lsi7 off the adcom pre and return the HK to buy.com.

then I noticed a set of 4 rca outs on the Adcom preamp. I run the 2 main outs into the adcom power amp and run the other 2 outs in the cd line in on the back of the onk. I run the psw111 of terminal b and the rtia1 off terminal A of onkyo. And LSI7 off the poweramp which is running out of the adcom preamp out.

It works perfectly! There is no hum or high pitched noise like h9 warned about. The power amp and the pre's feel warm to the the touch but not hot at all. I can turn it up as loud as it goes and the nothing shuts off!!

it sounds frickin amazing and I hear no difference in sound from the lsi7 than I did when I initially started. All I do is adjust the volume levels on the ONK for the sub and rtiA1 and then turn up the Adcom preamp which adjusts all 5 speakers simultaneously. Then I play with the pc speaker setup. it sends a chime to the left and right speakers so you can identify left from right channel. the problem is its rings both rtia1 at the same time for the right then rings the lsi7 for the left. ????


I checked my connections and instead of using terminal A left and right for the rtia1. I run the right RTIa1 off terminal A Right and the left rtia1 off terminal B right. (two rights???) but now it works. left chime right chime. lsi7 included.

SO my conclusion is. IT all worked out. mmadden was right all along. lee gave me a sweet deal and I got to use the preamp wisely. The HK is going back to buy.com and I get to keep the onk in the mix. Eventually I will sell the Rtia1 and get another set of Lsi9s for my main and use the lsi7 for the computer.

Thanks to everyone for the help. I hope this thread helps others in the same ship. I think Polk forum is amazing. I am an avid computer overclocker and am on xtremesystems.org. I cool Intel quad and dual core cpus using dry ice and liquid nitrogen. XS is the best overclocking forum in the world. I would like to say polk forums is the xtremesystems forum for the Audio Enthusiasts.
this is a huge compliment fyi.
Take care.

It has preout and main in plus a sub out. I thought man I'm all set this is exactly what I need.... so what happens is when using the preout on the HK it bypasses the integrated amp in the HK.

To use the pre out did you removed a pair of jumpers that went from pre out to main in ?If so then you disconnected the internal amp.You will need to get a pair of Y adaptors (1 female RCA -2 males RCA)so that you can reconnect it at the same time have a place for your pre out cable.1 male end would go to the pre out and the other to the main in.Then the female end will give you the pre out signal.

One other thing I like about this setup is I can adjust everything independently so I can turn down the lesser RtiA1's and run the Lsi7 higher so they are the dominant speakers in the setup. I wish you guys could hear my rig. I think you'd all be pretty amazed. I'm freaking out over here. I am speechless.

Yes. Exactly. The jumpers covered the preout l/r and the main in l/r. I dont have any y adapters and never thought of this. So I see what you are saying. the y adapter would basically still serve as a jumper except it would be a jumper with a female input in the center. sounds great!

But regardless. If the setup works how I described using the onk. is it worth $300 just to use the preout on the HK? Will it sound any better? Am I going to damage something the way I'm set up currently? Like I said. everything works and sounds amazing. no hums no high pitched sounds. no surprises like that at all. its all working flawlessly and I like the option of setting the lsi7 higher than the RtiA1.

Great to hear that you have it up and operational the way you want.Enjoy.:)

. is it worth $300 to just use the preout on the HK?Nope,$300 can buy you lots of new tunes.

Nope,$300 can buy you lots of new tunes.

Glad to hear this from another music lover. I am going to get Brand X Moroccan Roll and Unorthodox Behaviour on Vinyl. These are quintessential Acid Jazz/Fusion Albums. Phil Collins' first band he was in and plays drums like Neil Peart on five hits of acid! If you guys don't Know about Brand X and enjoy heavy drumming and rock/ jazz (don caballero). Listen to these 2 albums from the band that started it all. You'll be amazed.

Lost me on how you hooked up the sub and the PC, but I'm glad it worked out for you. :)




... and get another set of Lsi9s for my main ...
They are IMHO sweet speakers!! :cool: The only problem with them is that they keep whispering things to me when I sleep. They keep asking me for friends-expensive friends, like expensive new CD Players, and DACs, and stuff. Then they start playing some George Winston and gently put me back to sleep. :rolleyes:

fyi that cpu was rated stock at 3.33GHz.

I got it up to 5.5GHZ on dry ice. temperature of the cpu was -80c. I didn't break a world record on this one but I do hold the world record for intel Xeon X3350 quad core server cpu at 4.2GHZ from 2.66ghz stock.

Any Richard D. James fan's on here?
