I am looking for pretty good sound Q and I need it to hold up to the ammount of power it says it will put out. Ok how about this... I have 1 polk db124 12" hooked up right now in about a .8? cu foot enclosure. I will be hooking up another one as soon as I get my other box done in a couple of weeks.

I want the amp I get to perform good now and after I get the other sub in, which of these would be best

Pioneer GM-7100M - 250 x 1 rms at 4 ohm, 360 x 1 rms 2 ohm
Directed Audio 750D - 275 x 1 rms 4 ohm, 400 x 1 rms 2 ohm
Alpine MRP-M350 - 200 x 1 rms at 4 ohm, 350 x 1 rms 2 ohm
Sony XMSD51X - 250 x 1 rms at 4 ohm, 500 x 1 rms 2 ohm

these are all right in my 100 dollar price range, let me know what you guys think, or if you know of any other amps in the ~$100 range that would be better to drive 1 of the db124's now and two of them later please let me know where I can pick one up.

Oh by the way, this is going to be going with a dx 6.5" component set I have up front powered off a kenwood excellon 75x2rms amp.

Go with the Alpine amp. It's a solid performer and even though it is rated the lowest, it will most likely out perform everything else in the list. A second choice would be the Pioneer. The Sony isn't all that great and I've never heard of Directed Audio.

audiobliss

11-03-2005, 02:41 PM

Alpine. Stay away from the Sony. I've never heard of Directed Audio, either. The Pioneer would be an acceptable amp if you had not mentioned the Alpine.

Directed is the company who, from what I can tell, owns Orion, PPI, Viper, etc...

MacLeod

11-03-2005, 07:27 PM

Yup. Directed is DEI which owns a/d/s, Orion, PPI, Viper and a couple others. They make decent products but never were my favorite.

John's right, the Alpine is the best of the bunch. It was tested in PAS mag a while back and spat out over 400 watts at 2 ohms so you get more grunt than you pay for and since it only retails for $200 its the best mono amp for the money.

Id say the Directed 2nd and the Sony and Pioneer 3rd. They will both make their rated power and are built well enough but theyre nothing fancy. Alpine all the way baby!

yeah I have had this Alpine mono amp for about a year and a half and it sounds great. A crutchfield rep told me the alpine v-power amps are the number one selling amps in the united states. He said they sell more alpine amps than any other brand.

Probably do.

Theyre built very well, make their rated power and are relatively cheap! That 50x2 amp for $110 is a gem!

directed is a bunch of bastards. period.

i vote the alpine. - unless you can get into an mtx mono 800w or a polk C500.1 for the same price, but i don't think you're gonna be able to - add my vote for the alpine.

ok, thanks guys for all your help. I think I will go with the directed amps, just because I don't have very many people I know that own them. I like to be different and i want to blow people I know away with Polk and some other brand they have never used like directed. My friends know absolutely nothing about SQ and have always thought fosgate and alpine were the way to go on everything. So i can't wait to make their jaw drop over my all polk system with directed amps. Thanks again for the help

11-06-2005, 08:55 PM

Why in the hell do you want to go with a directed amp. If you want to be different there are a lot of better choices that people don't own than a directed amp. If you are going with a momo system why not go with the momo amps. I mean it's not everyday you see someone using polkmomo speakers in the first place. I mean people ask me everyday what is polkmomo because they see the stickers on my back window. Car domain runs specials on the momo amps pretty often i know on the 300x2 for 199.00. You would be a fool to buy a directed amp when you could own a momo amp for 200 bucks. Thats a steal for the power and sound quality a momo amp has to offer.

audiobliss

11-06-2005, 11:17 PM

I would also suggest the Alpine or (preferably) the MOMO over the directed. However, if that's what you gotta have, you gotta have it.

But it's be superb with the MOMO amp and awesome with the Alpine.

PoweredByDodge

11-07-2005, 02:55 PM

directed amps are very poor quality for SQ and just a shitty build in general.

if i do recall correctly, they have a slew rate of 5 v / us, which is utterly abhorred.

mtx used to guarantee better than 20 v/us... and i'm sure most "good" manufacturers are in that range or better. zapco was what, 50 v / us?

damping factor on a directed amp is less than 50... ewwwwwwww.

zapco's up near 1,000.... i'm sure polk amps are in the 200 or better range... same goes for alpine.

directed is not the way to impress anyone. they're worse than fosgate dude. that's no lie.

True but you wont hear a difference.

If I shoot you in the face with a slingshot youll be pissed.
If I shoot you in the face with a BB gun you could be injured.
If I shoot you in the face with a .22 you will be severely injured possibly killed.
If I shoot you in the face with a .38 youll be dead.
If I shoot you in the face with a .44 youll be dead.
If I shoot you in the face with a .50 youll be dead.

Now each of these guns are better performers than the previous but are you any more dead with the .50 than with the .38?

Same with slew and damping. All amps made today will be good enough that you wont hear the difference between the 50 or 1000.

Like THD. .0003% is a whole lot better than .05% but it doesnt matter because you cant hear either of them!

regarding thd - anything under 0.5% i would say is acceptable and most likely not audible.

slew rate and damping however are not related to THD - THD is a byproduct of the amplification process. slew rate and damping are not by products, but rather characteristics of the quality of the materials and design of the amplifier.

shitty slew rates and shitty damping are not only audible in some cases but given the right circumstances can lead to driver fatigue / failure.

Right, but my point is that even Jensen amps have damping and slew rates well above the level that would be audible.

Ive heard them both and there is nothing wrong with DEI. Both will easily make their rated power but the Alpine will be built a little better using better components.

Will the DEI suck? No but Id rather have the Alpine.

Just so ya dont think Im pulling this stuff outta my arse, here is an excerpt from an article Robert Zeff wrote:

I'd like to take this time to dispel another myth, that super high damping factors make an audible improvement. A damping factor of 50 means that the amplifier's actual output impedance divided into the load impedance is 50. In this example the amplifier's internal impedance is .08 ohms. A typical four ohm speaker typically has 3.2 ohms of internal DC resistance. So, the actual damping factor could not be better than 4/3.2 = 1.25! That is why emphasis on ultra high damping means nothing sonically.

(Robert Zeff started a little company known as Zapco which makes some of the finest amps on the planet, so I would say he qualifies as an expert)

neomagus00

This is from a test he did on a Diamond amp. Even more revealing is when he did the listening test he spoke nothing about soundstage widht, tightness of bass, warm or bright sound just that it was completely neutral and had no distortion.

that makes no sense... "damping is load divided by output impedance" -- he talks about an amp with a damping factor of 50, and then proceeds to say it's actuall 1.25 ... so who wasn't thinking? it is what it is - things don't magically change.

he has severely over simplified the matter. and i can't recall one zapco amp i've ever encountered with poor specifications... some are obviously not as great as others, ie the reference series, but the reference models still outdo just about anything else on the market. if it was so unimportant that mr. foot in his mouth wouldn't be investing the time and money to build his components in that fashion... fact is - it's not just a matter of using better parts, it is a much more involved design and testing process to build am amplifier with good specifications. its disgustingly longer to build one with GREAT specs.

i'm not saying that a 1,000 damping factor is necessary, but something between 150 and 250 would be a nice thing to aim for... 300+ would be peachy but unnecessary. less than 50's a joke.

High damping factor plays a key role in the linear control of a subwoofer. It gives woofers tighter precision control for better sound quality. That has been proved. I had a mtx thunder amp one time and you know mtx amps have high damping factors. I can't remember what the numbers are right off, but man those subs sounded so good on that amp. It was amazing how tight and controlled the linear movement of that sub was. Im a true believer higher damping factors do make a difference. I agree tho there is a limit to everything you only can get so much out of something.

He has NEVER NEVER NEVER said all amps sound the same. It kills me people still dont get this.

You pay more for an amp because it will make more cleaner and usable power, it will be built better and last longer using higher grade components, it will have higher quality crossovers and EQ circuitry, it will have better connections and power supplies. You dont pay more for an amp because it has warmer bass or a broader soundstage.

Dude, thumb thru some magazines and check out the amp reviews. Notice the frequency response graphs are always ruler flat. Thats like taking 2 identical EQ's and setting them to 0 db and then saying one has more bass than the other.

Not to mention, he wasnt the first to come up with this by a long shot and hes definitely not alone.

a frequency response graph for any amplifier - even a bargain basement "Urban Audio" that K-mart used to sell - they should all be ruler flat from about 20 or 30 hertz up to say 15 to 20k hertz.

the better amps will be ruler flat from say 15 hertz up to say 30 k hertz... or even further... but most speakers won't respond below 20 or above 20k so it doesn't matter.

what makes one amp different from another is power output, total harmonic distortion (signal to noise ratio included), stereo separation, efficiency, output impedance, ability to handle varying loads (specifically the load you intend to put upon it).

"Warmer" and "broader soundstage" are misused terms... at one time i'm sure some audio guru used those words as "shorthand" or "paraphrasing" for meaning that the amp had little distortion, great stereo separation, and reliable performance that didn't change once the bastard got hot during use.

amps don't have more bass... eq's don't have more bass... nothign has more of anything -- except an original signal source (cd, cassette) or an eq that has been turned on (bass boosted, or trebble boosted).

... and cast any stones you guys want - i'm not smarter than anyone here. i've just made it a point to pick shit up along the years... look at some posts i put up a few years ago - i sounded like a raving lunatic and was completely wrong... now i'm just a raving lunatic.

Yeah and those Hifonics or Rockfords wont be built nearly as well as an Xtant nor will it have cool features like ARC or the superb cooling technology of an Xtant. Now you can pay more and get some RF Power amps which are built like tanks and stable down to 1 ohm too.

I dont understand why you cant get this.

Nobody has ever said all amps sound the same.
Nobody has ever said $100 Profile amps are as good as $1000 Tru amp.
Nobody has ever said there are no differences in amps.

Youre such an Aggie.

Take a 50x4 Profile amp and a Xtant 75x4. Now the Xtant is going to be much more powerful and cleaner than the Profile. Itll be cranking out good clean power long after the Profile is clipping and sending out 10% THD signals. Plus the Xtant will have that cool ass ARC feature and better crossovers and bass boost EQ's, so the Xtant will be a much better sounding amp.

Now if you take them and turn off all those cool features on the Xtant, level match them to where theyre playing at the same volume within .05 db of each other and both making comfortable power (i.e. both at around .05% THD) and give a listen and youll hear no differences.

"now i'm just a raving lunatic"

And it seems you have a lot of company... :D

Im trying to follow along here, and heres what I got so far:
1. amps are only as good as the components that comprise them, if you think about it, the tolerances in components can be + or - 5% effectively making every single amp different even under the same model/manufacturer.
2. Sound amplification and reproduction relies on electricity, which can be subject to many different elements. The copper used in one set of wires may have a slight bit more resistance than another, altering the sound. Copper is copper, but the manufacture varies widely.
3. Since saying that "this particular cable/amp/thingamabob has a higher resistance in its upper registers, and also seems to blend both channels of the stereo recording" wouldnt make much sense to the average joe, terms such as "warm" "bright" and "soundstage" are used since it more describes the sound rather than the scientific.
4. As long as these electical differences remain, and people's hearing and taste varieties remain, there will never be a definite.

neomagus00

11-10-2005, 10:48 AM

1) yes, amps are made of components, and the better amps use better components that have tighter tolerances - higher cost, but better build quality

2) electricity runs amps - true, but excepting the amp's power supply, this is external to the amp and therefore irrelevant (as far as internal wiring etc. goes, that's under #1)

3) The contention is whether or not there is a difference at all - whether one amp can be warmer or brighter or have a wider soundstage, because after a certain point the human ear simply cannot detect a change, and very nearly every amp on the market today has passed that point.

4) Naturally, psychoacoustics will always play a factor ("my amp cost me two thousand dollars and my left teste, it MUST sound great!"). Here, i think mac summed it up best... with all else equal (i.e. turning off all the neato features you paid so much money for), after volume-matching two amps (i.e. losing the extra power and/or headroom of the better amp), they'll sound the same (read this again without the parentheses and it makes more sense :p)...

hellohello

"electricity runs amps - true, but excepting the amp's power supply, this is external to the amp and therefore irrelevant"

Im not one to argue, but the sound is converted into electrical signals, so the power supply would have an effect, if it is indeed part of the amplifier. Now Im wondering if you were speaking of the "external" power, hm... With so many variables involved, especially if one is comparing two amps/wires/whatever.... makes thine head spineth as if it orbited the sun.

That's a good point. If you have a nice amp with all the extra features, you're definitely going to use them. So, this debate is not over whether or not they should cost more or whether or not you should buy the nicer amp, just whether they sound different with everything being equal.

(Notice I've yet to state my opinion.)

hellohello

11-10-2005, 11:24 AM

"The sounds is already nothing but an electrical signal when it leaves the HU."

Precisely, Mr. Bliss, and therefore in its electrical state it can be affected long before it even reaches the amplifier, certainly if the signal wire is too close to the Power line, the power line "leeches" into the signal. Since it has been stated that " (roughly) all amps produce razor flat response" Im suggesting that its more the actual sigal being sent to the amplifier.

audiobliss

11-10-2005, 11:29 AM

Well, naturally everything in the signal path has the potential to affect the electrical signal in a manner that would be audible. Both the CDP, the HU's processing, the interconnects, their placement in relation to the power cables, the amp, and the speaker cables. I mean, think about the CD and the speakers - they have a BIG effect on the way that electrical signal sounds!

However, I fail to see your point by bringing this up. The discussion was about amplifiers and how they affect the sound of the electrical signal. While that in no way implies nothing else affects the sound, it also has nothing to do with the other equipment. That'd be a whole 'nother discussion.

... higher end equipment uses parts that have tolerances of about 5% to 1% depending on manufacturer.

... extremely high end equipment uses parts with 1% to 0.5% depending on manufacturer. I've never seen anything better than half a percent... I honestly don't know if it's within mankind's means to make something that "perfect".

... the "law" (for lack of a better term) of "equally probably screw ups" would tell us that over the course of amplifier manufacture, there will be just as many screw ups in the "good" direction as in the "bad". And the chances of both a "good" and a "bad" happening within ONE amplifier are drastically more than that of two "good's" or two "bad's"... as a result, you'll he extremely hard pressed to find two identical models from one manufacturer that ACTUALLY post crucial factors like THD, slew rate, signal to noise ratio, etc that differ by more than say 2 times a single variance (ie. 5% x 2 = 10%). Figure that for a "really pimp amp" and its 0.5% x 2 = 1%. this adds to people thinking that high end stuff is more "reliable" -- not only is it more durable (usually), but it is more true to its specifications.

... the soundstage is simply WHERE and HOW you perceive the "virtual stage", as if there were people on a stage performing. the key factors are stereo separation and signal to noise ratio and - dun dun dun - what speakers you are using, where and how said speakers are placed. Soundstage is a "symptom" of an amplifier, not something unique... it's not like measuring THD or measuring slew rate. you can't measure a soundstage... it is a perceived quality (say on a scale of 1 to 10, ten being best) that we give the total audio system (amp, signal source, and speakers) ... all 3 have to be working in tip top shape, and have great specs, and be placed properly in order to get a "10".

Theyre pretty serious about their amps too, even pre-amps! Im in the middle of a debate over there now on this very subject, and not making much progress either. They just dont seem to understand that Im always right. :D

Yeah I am excited. I am going to be running it 2 ohms, so it would be putting out 800 watts rms, 400 to each of the polk db's. I didn't want to underpower them I am just going to have to set the gain conservatively

All this talk about Directed amps and such, I just got a Directed 1100a and two kicker solobaric 12'' L7s. I don't know much about much, but what's it worth in new condition and is it worth having? ..

Well I finally have the directed 1500d installed and I love it. Absolutely lives up to it's power rating, good sound, enough power reserve for consecutive bass hits, has all the features I need, plus its class d so it's effecient. I have owned quite a few other class d amps, and I would have to say in SQ this beats the other ones hands down. Dont know how much I would pay for that setup though, I dont like kickers.

tokin - i think you'll get a much better response if you start a new thread, it'll draw a fresher crowd...

... and if you state how you 'got' this 1100 watt amp... since you "don't know if it's worth keeping" - and you have only 1 post... and 9 times out of 10, such questions, regarding high dollar amplifiers and subwoofers, from people asking if they're "worth keeping" are usually people who stole them.

i can just see a thief running down the road with a set of Polk SR components and an IDmax in his arms going "i wonder if it's worth keeping".
