Just picked up a nice B&K AV5000 amp. Someone brought this amp to the local store to sell and they don’t deal in consignments so I picked it up. This amp is the model before the Series II issue. I was told the only difference between AV5000 and AV5000 Series II is, that Series II is 125W x 5 instead of 105W x 5.

Also, the amp has a 12V trigger and gold plated binding post. The front black aluminum plate entertains a pilot light and a power switch very plain and simple. The amp weight around 40 lbs. and came with original box, owner’s manual and is in pristine condition.

I bi-amped the F/R (Ch. 1+2) and F/L (Ch. 4+5) and Centre is connected to Ch. 3 as recommended by B&K and the surround is powered by Denon AVR3806 prepro.

Nice improvement to my rig. Just thought I will share this with you.

Strange that they actually spelled out "MINUS" and "PLUS", instead of just "-" and "+". I guess that's OH-KAY if you understand English.

And thanks for not posting pictures of the box.

The B&K amp works really well. My Rti8s came alive with bi-amping. I found the 8s were on a bright side with the Denon 3806 alone. After I hooked up the B&K they mellowed down and the midrange is a lot clearer. Also, the bass is more powerful and tighter.

After all hookups I played Diana Krall and I was amazed with her voice. Playing HT and music is more pronounced and smooth. Well worth the investment.

Hey Demiurge,

There is one on eBay for grabs.

It is the B&K AV5000 series II 5x125W and it looks like in a good shape.

Take a look. :)

This amp is awesome. I just looked at your Sony on web site and it has preouts. I biamped my fronts and run the 5th chanel straight from the amp.

You would be really pleased with this amp.

Using UltraLink inteconnects and these work well for me for now. Yeh, the caps are awesome. I thought it was all about "Watts", but it really is all about "power supply" and quality of the amp. My Denon 3806 is rated at 120WPC x 7, but the B&K will kick its a$$ any time.

Sunday morning at 6:00 am I re-calibrated the whole setup using the mic that comes with my Denon. You might wonder why Sunday?..............Well, everyone on our street sleeps in on Sundays. Between 6:000 and 7:00 am there are no cars driving on the street or any kind of additional noise whatsoever. I found this is a good time to calibrate!

I'm sure your neighbors appreciate your 6am calibration session. With the test tones the HK 635 puts through my Omni s-12 sub, I think I'd be evicted from my apartment if I ran it at 6am.

It honestly scared the hell out of me when I first hooked up my sub and ran the EZEQ setup. Gave me chills. . .

Out of curiousity how does this B&K stack up to my Rotel (see Sig. below)
I know they are both good amps, being a fan of both I wonder what you guys think comparing these two models. The Rotel I believe has 110 x 5 and they are roughly from the same time period in audio history.

B&K AV5000 (Series II) (http://www.bkcomp.com/pdf/AV5000SERIESII.PDF)
125 wpc 8-ohm 185 wpc 4-ohm
30 amperes peak-to-peak

Rotel RB-985 MKII
Not finding spec info on the Rotel site...

Rotel RB985 MKII (http://www.rotel.com/support/pdfs/manuals/Rb985mkII.pdf)

They only list an 8 Ohm spec (100 WPC) but say 4 Ohm loads are OK.

I've got one using a Denon 3805 as pre/pro driving Polk 4 Ohm in walls. I finally diverted some money away from the two channel fund....

EDIT: No 12 volt trigger though, but four outlets on my power center are controlled by a 12 volt trigger so I don't have to walk up to it.

It's cool having a new amp, you get to relisten to all your stuff, B&K is a solid choice.

Not sure how I missed seeing te 985 info, but WTF...

B&K's power consumption at 1220 W, indicates it's the beefier choice, but the Rotel is likely around the 140 wpc into 4-ohm and in the low 20's for peak-to-peak current. More than respectable...

1200 compared to 800, correct?
is the way the unit utilizes this that really counts?
as good as an amp as it is I feel my 9's are still hungry

No kidding! I was concerned for the integrity of my house after running the EZEQ setup the first time. Shook the hell out of the whole place. My dogs were cowering in the corner wondering what the hell had attacked our house! Of course one of them barked in the middle of a test tone, so had to run it again...and again....and again. (they're not very well behaved)

Anyway, didn't know my velo could even create the sound that came out of it during the the test tone.

Yeah, WTF, usually your into multiple bases or home runs with your posts. I'm gonna write this one down.:D

IMO, the B & K is a more robustly built amp. The RB985/985MKII has one weakness that can surface during rough handling during shipping. The RCA jacks for the R & L front/rear on either side are mounted to a board that is attached to the chassis bottom. The RCA jack is then secured to the back panel with a screw. You twist the case, and you can break the RCA jack block off the circuit board. This will be evidient when you connect it and lose front/rear of the same side.

Other than that it ain't a bad amp.

SCR,
The sun was in my eyes????

S/N (A-weighted) 95 dB If you can hear the difference between an 90 and a 120 dB S/N ratio, my hats off to your audio ears. Once the rises above 90 dB, differences are negligible.

I will grant you that a higher ratio is indicative of better curcuit components being used and/ or a "cleaner" signal path design, but whether or not that translates to a better sounding amp is the question.

And the answer is only found in one place... your ears.

By the Way what was the series two issue Gator speaks of?
Does he mean issue as in release?

I was told the B&K AV5000 amp is the earlier release model version. The B&K AV5000 Series II amp is the later model release with 125 WPC instead of 105 WPC.

B&K realized they were rating this amp very conservatively. They raised the wattage from 105 WPC to 125 WPC in order to compete with the other brands in the same wattage capacity. Otherwise these two amps are the same.

B&K AV5000 amp: 105 watts into an 8ohm load, 185Watts into a 4 ohm load (all 5 channels driven simultaneously)

B&K AV5000 Series II amp: 125 watts into an 8ohm load, 185Watts into a 4 ohm load (all 5 channels driven simultaneously)
