I bought a new one about 2 months ago - it is a fantastic amp. It tends to run very warm, so make sure it has enough ventilation. You should know that B&K does not answer their phone anymore, and may have ceased operations. having known this, I STILL would have bought mine, I like it that much.

Good Luck,

Patrick

Great amp. They do run pretty warm, maybe hot would be a better description so they need good ventilation. I have the newest version, with a different face plate and isn't THX certified, but other than that I don't think theres much difference.

Great Amps!
Very clean, plenty of power and handle 4ohm speakers like a champ.
The amp does run hot so make sure it's well ventilated.

I agree with all the above, I have one (although it is an S2 faceplate which is the model between the one you are looking at and the newest version) and it is a nice one box solution. I can't really say it made a difference to my ears over my receiver but I won't have to ever ask myself if I have enough power.

SO whom ever purchased this B&K amp, I wonder what are they're going to do now that B&K is out of business...Freaking great time on the part of the seller!!
Not soo good for the buyer!

And they paid a pretty nickel for it, I was watching it, and it sold over 1200..plus that ridicules shipping price..Dam..

I would guess he will use it as he intended. Just because they went out of business doesn't mean the amp is no good anymore. Most amps will work for many years without any problems. If something goes wrong I'm guessing some repair shop would be able to figure out whats wrong and repair the amp.

Yeah that true, but there's always this nagging concern now.I for one wouldn't want just any repair serves center diddling with my gear, especially in that caliber. Heck I remember volunteering to take a good friends Sony AVR to fix, which was out of warranty. The thing came back unrecognizable by the owner..I'm sure B&K would take better care of anything that passes through the facilities.

The assets of B and K were acquired by ATI (www.ati-amp.com) based in Montebello, CA. They own the ATI, BGW and Audio Access brands and are also the OEM supplier of amplifiers to a number of prestigious companies. Per statements from ATI, they expect to continue the B and K brand with products again available around March of 2011.

Question for the B&K amp owners

I just purchased a B&K 200.7 S2 used. I just set it up for the firs time last night did some demos watched half a movie etc etc.

Is it normal for this thing to get INSANELY hot. I mean it was very very hot to the touch? is this normal and ok? I want to keep this amp for a very very long time so I am concerned at how much heat it was putting off

Mine runs hot, but I don't think insanely hot. I'm powering 5 PSB Synchrony Speakers crossed over @ 50hz, and when I don't have the A/C on and I'm watching something with a lot of action and the volume cranked - it gets pretty hot. Mine is open all around, with about 6.5 inches free space on top from the next shelf. What speakers are you driving, what crossover point are you using, and what is the ventilation situation?

My ventilation will change (this is just temporary) but its sitting on a shelf with nothing above it at all, nothing to the left and something maybe 8" away on the right... so id say ventilation is a non issue.

I am driving Klipsch Reference 7 speakers
2 RF-7s, 1 RC-7, 2 RS-7s, 2RB-75s

Its a brand new pre-amp that I haven't fully setup... I believe the default was 80hz crossover. (Again this will change as well)

This is my first amp/pre-amp so maybe its not insanely hot but sure does feel like it to me... much much hotter than my receiver ever got. Its very hot to the touch, like I could leave my hand on it.. but I wouldn't want to :-) I can see if I can take some measurements tonight if that would help.

As far as I know, it's normal for B&K's to run hot. Years ago, I had an ST-140 2 channel - it ran hot. My 200.7 Ref. does, too. Maybe you just aren't used to this; as you are coming from an AVR?
