Bryston VS Musical Fidelity

TVAD I don't know why I softballed your question, when you said, "I don't know what slow means" or words to that effect.
For many years now, rise time, slew rate, have become lesser talked about figures in some circles than in others.
I think the now deceased John Ivorsen of Eagle, was the first designer to talk to me about the speed and relative speed of amplifiers, and how capacitive loads dramatically effect the measurements: which is why different engineers have different measurements for seemingly the same product.
He also, this was in 1986 talked about how most designers did not understand the proper utilization of 'current' in design work, then he started losing me at that point in my career. At that time his amp was vastly 'clearer' and I guess therefore sounded 'faster' to me, in the way that tubes offer more delicacy (to me) and low level resolution.
My early days with Bryston date to 1985, then as I traveled the country for THIEL. Their distribution became spotty when the brothers split and Chris and John went separate ways, Chris going with Classe I believe.
But explaining speed is almost like explaining, as I said, tube delicacy. It's not that it doesn't exist, its just hard to make clear.
That is as when people talk about S/N ratios and they don't realize that 80db s/n ratio is 1/10,000th, then begin to what seems like a nit pick, with 80 db versus 100db, once you're already at 1/10,000th, isn't that already good?
So speed--yes, I think, that to me Bryston sounds softish, and slower than many other good amps. If that sounds like an indictment I apologize. But we ALL hear things so differently, one thing that is obvious to one person is not as obvious to another.
At 56, I had a hearing test, and my left ear was rated, according to the doctor, as 'perfect, and really remarkable', (he had the good grace not to say, for your age.) But the scale was not age relative, it was just perfect. I now realize why 'possibly' I hear and quantify things other people don't. Please don't take that as bragging since most of the things I hear, are unpleasant, so perhaps a curse in some ways.
I am sure your amp is excellent, just not my personal favorite.
Spectral, probably sets the world on fire with it's recovery times, yet to me sounds stark, and dry. So what does that tell me? Who knows?

Lrsky, thanks for the explanation. You didn't answer my question, though, about which series of Bryston amps you sold or have heard. It's generally accepted that the sound of the Bryston amps has been refined considerably from the original "B" series, to the "ST" series and further in the "SST" series. So, while I would never question your ears, or your opinion, since it is your opinion, I believe it would be beneficial to the discussion to know with which series of Bryston amps you are familiar.

Actually I did, in that I (even though I did not include the dates) stated that I heard plenty of Bryston's and their current Lexicon which is their OEM product.
Bryston is so damn good, that it is ridiculous to have any nit's but if you can imagine a square wave with the front part rounded, that is what I hear. It doesn't sound like a square wave, but a 'rounded' wave to me, with the leading edge missing.
Hope this helps, AND we still have the offer of the master bedroom for you and Chris to visit you dog. Please come to Louisville, hear my LSA's and let me show you Louisville.
You can meet the entire LSA crew, and take home a pair of LSA 3's in Rosewood.

Lrsky, the Bryston amps and Lexicon amps are two different animals despite Lexicon being a Bryston OEM product. A quick look at the specs shows the Bryston amps to have better Signal to Noise ratios, double the damping factor, lower THD, and the list goes on. I would argue that based on the published specs, hearing a Lexicon home theater amplifier may not equate with a Bryston 3 or 2 channel amplifier.

I might point out that Bryston, in an effort to justify their pricing and quality differences, other than the obvious warranty differences, would intentionally show much better spec's than their OEM Lexicon counterparts.
I would bet that the spec's are identical on both pieces, and that the difference is one of marketing. Smart, and meaninginless in terms of differences.
I. E. Why buy a Bryston, other than the 20 year warranty unless the spec's are different?
I know you like the Bryston, and well you should. It has been a staple in the industry for years, and only a 'taste' difference, in terms of 'sound' would lead one to a different product. I prefer it overwhelmingly to Krell's high frequency 'hash' for example. My preferences lean to tubes and their delcate presentation relative to solid state. The distortions of tubes are pleasant versus, unpleasant in solid state, with odd order harmonics.
Think about your system, and how the Bryston sounds better in some ways. That has to do with the speakers, capacitance etc, as much as anything.
