REAL WORLD OPINION - ADCOM 555 ii vs BRYSTON 4B

In my post I was leaning over backward to be fair. While design is important build quality is even more so and reportedly the 555s from different sources did not sound the same so you do not really know what you are getting. I have not had Bryston but they are recognized as a top amp by everyone, the 555 was a good amp for the money. Unless the Adcom is half the price or less and the difference is important I would get the Bryston.

you did not mention which type of speakers you are driving.
the 555 can sound bright on some; benefits greatly from parts upgrades. The 555 Mk2 has a bigger power supply than the original, but still small when compared to the Bryston.
The bryston will give you more bottom end control. A more fair comparison to the Bryston would be the Parasound 2200 Mk2. The Adcom while at its price point is OK, is not in the same league as the Bryston or Parasound 2200 Mk2.

I haven't heard these in the same system with the same speakers as you had requested, but I have heard them both. This is an easy one, Get the Bryston!

I would consider Bryston Class B
and Adcom Class C based on the Stereophile rating system.

You may also like a McCormak, as it has better midrange than the Bryston, however not as deep bass. So it really depends on the speakers you plan on hooking them up to.

Thanks guys. This is for a studio monitoring setup and will be running NS10's or Tannoy System 8 DMT. I currently use a Hafler DH500 on the NS10's and it has a lovely warm creamy character (like a Neve mic pre). I had borrowed a Bryston 3B for a while and that was "harsher" than the DH500, but I would say more "accurate". I would like an amp that makes me mixdown a "warmer" sound, so the Adcom sounds like it would point me in that direction since it has a tendency to be brighter. Its a tool for a job.

This sounds counter-intuitive to me but you're the "professional".

You want bright....the Adcom will give it to you, in spades.
