I think many audio engineers whether in the recording side, or in sound reenforcement, will praise Bryston. This is because the gear is neutral, and is extremely well built.
In a recording studio it is more important that the sound be predictable and as neutral as possible. A "prettier" sounding amplifier might work better at home, but it will skew the way recordings mixed and mastered using it will sound. A pretty sounding amp may also obscure sonic information that can cause a recording to have problems that go unnoticed until it is played back on other gear.
So, I guess it depends on what one wants from their audio system, and more specifically, the amplifier in it. This doesn't mean "pretty sounding" amps are bad, they're just not the right tool for many professional applications. I also believe that many pro audio systems are not right for home listening. Each person should listen and decide which is right for him or her.
