B&K with bryston?


Hello all,

I am wondering about a possible scenario for my first setup.

I am finally purchasing my front mains...JM Labs Cobalt 816s. I don't have a reciever/pre-pro +amp yet, and I have a possible combo I would like to get some advice on.

My speakers are super efficient...91.5dBs with a max power handling capacity of 125W. Until now I have been planning on buying a reciever, but I was browsing, and found a Bryston 2B-LP amp for sale, cheap. This amp has reported 60W, but that is pure bryston power. How would this amp work with these speakers in conjunction with a B7K Ref30? I would love to grab a Bryston SP-1, but that is a bit out of my price range. This would also allow me to add a Bryston 5B-ST at a later date, to run fronts and center, and move the 2B to the rears when I purchase the rest of the system. Slick.

So, does anyone have an opinion on how well this combo would work? I really want to go with Bryston power now that I found the 2B for so cheap, and the 5B for a grand. If not the B&K, (but in the same &1500 neighborhood) what other manufacturer?

Thanks,
Z

Hi Z,

Since the soapbox is free at the moment, I'll chime in a couple of my very own opinions, totally free of charge! ; )

First, forget about the receivers. Time waster.

Pre/pros are all a bit pricey, as you've noticed. You pay for them to develop or license software - these things are NOT simple, elegant 2-channel components - quite a bit of work goes into them. Lots of complexity, lots of marketing, lots of brand identity wrapped up into flagship processors - they almost never come cheap.

I agree wholeheartedly with your observation about bang for the buck with seperates, especially at a lower price range. I've found many entry-level integrateds (not even to mention receivers) to be grossly overpriced, underpowered, and oftentimes terrible sounding.

60w of pure Bryston power is still 60w. They don't use any different watts than Conrad Johnson, B&K, McCormack, or alot of other gutsy amps out there. 60w of SS power just isn't enough, unless it's a class-A circuit design, which it's not (most are AB - whip out your circuit design manual or look up the topic on the web for more info). I suggest 150w or above for your mains. The speakers you have are above average in sensitivity, but not enough that you can get away with markedly lower power amps. Also important is the impedance curve of the speakers and your listening material. If you have a pair of speaks that hits 1.8 ohms at 50 HZ and you listen to a lot of techno, your amp better have some lead in it. More power also equals more "control" over the speakers, and usually a more dynamic and fuller sound. Of course, some manufacturer's amps differ in other ways as the wattage increases, so it's important to listen to them all if you can.

Depending on how important the latest "features" are to you (to me, they hardly matter), you may find an interim option of buying a good SS amp and a slightly older preamp/processor (even of dolby prologic vintage - mid 90's) a good first step. Adcom and Lexicon make some very decent pre/pros that you can get cheap used to hold you over until you settle on a long-term processor. These will handle all A/V inputs, video switching, surround sound level adjustments etc, just not have all the latest codecs.

I agree with Unsound about surround in general. Surround sound is *really* tough to get right. Just putting a couple speakers here and a couple speakers there doesn't begin to address the subject. The room itself is most of the struggle. I've found most 2-channel setups more involving and "room-filling" than the same systems with more than 2 channels driven. I still try to do both, but the truth is in the telling, which is why people like Unsound still cry "aaaarg, me wooound!" when people mention surround. Do yourself a favor and make sure any pre/pro you buy has a 2-channel mode, number one, and that it actually sounds GOOD in stereo. You'll find yourself there in between movies!

Cheers, and best of luck
