Bryston amps VS the rest... too clear and neutral?

Bryston amps tend to do a minimalistic job for the audio system. Extreams cannot be handled well by Bryston since they have bi-polar output stages that are very depended on weather, speaker impedance curve and... and... temperature of the amps.
Despite being absolutely linear in the measured ouput characteristics it might clip in different freequency areas depending on the speaker curve.
Please note that clipping might not be audiable but it will definitely cause a fatigue. An audiable clipping is characterized by trembling sound of the speaker driver. In SS case it is very distructive for a speaker. In many cases it will clip on higher freequencies not being able to drive a high impedance loads. That's where the rated output power realy drops down big time and clipping can occur even on arround 12:00 volume positions.
Most-likely 2-way speakers will be the most suitable for Bryston amps since the curve is not so complexed. Efficiency is not the key in this case since Brystons are enough powerful.
Despite having less gain and higher output impedance 100%MOSFET SS amps tend to be much more stable to different loads and so less fatiguing and very close to tubes even in some cases more preferable.
In your example with Logans, Classe I define simply extra-cost Bryston. If you hook-up Bryston with Logans I bet you wouldn't understand what's realy going on:^).
But do not blame Bryston too much. For a budget among Krell, Classe or even Edge the Bryston is a champ since it sounds not worse than Krell, far better than Classe and much less costly than both. Unbeatable 20 years transferable warranty, unbreakable power supply can tell you that it has a hell of a built quality.
I however, believe that these models I described above are "pedestrians" even including mega-buck Krells; but look out, there are plenty of "porches" on the market:^)

you mean Porsches? I am curious as to how bipolar devices don't reproduce extremes very well. The weather, speaker impedance, and temperature affect all devices. However, temperature is by far the most important since output impedance in a good design will be very low anyway. It is true MOSFETs are better at handling temps (read stability) due to their negative temp coefficients but their transconductance is terrible compared to BJTs. The BJT temp problem is easliy remedied with a good design and its excellent transconductance remains. I am not knocking either of them since they each have advantages and drawbacks but linearity is what we all desire the most.

Marakanetz, your comments about Bryston are confusing. If I read correctly your are not a big fan of Bryston, however, your system link shows a couple of bryton components. Only asking because I to am looking into the Brystom 7bst monoblocks to power my legacy focus speakers. What I have heard of brytosn amps, sounds clean and full. While I have not heard to monoblocks the 14bst had very pleasant sound quality. While I auditioned the Krell line I was not impressed. I was truly moved by the Audio Research vt100 but am not sure I want the tube problems that go along with the sound quality. As always, questions comments and learning are what this is all about.

Pbb, if you look from the right angle, the United States are also green:^)

I have had both Bryston 3BST and Classe CA200. Classe although warmer and a bit richer in midbass, it had terrible vocals. Bryston was always very honest and pure. I think the only time I heard it sounding grainy was in the bridged mode. I have heard the ST and SST series head to head and must say that SST is more refined, vocals float ,bass is more defined and overall soundstage is improved. After trying numerous amps one thing I observed was that movie dialogs through Bryston are perfectly understandable. Their amps is very coherent, they don't color anything and paired with neutral speakers will show all the weaknesses in the upstream. I've moved to Spectron Musician since then but I believe Bryston offers very good value, reliability and value.
