If their specifications are the same, of course they sound the same, unless the specifications aren't correct.
I don't think Bryston would be happy with having their amplifiers sound quality being equated with a mass market receiver with the same distortion specs. That would be saying the $4k 2.5B 3 cubed amplifier sounds exactly the same as my $100 used Pioneer receiver because the distortion figures are the same.
So your position is that Bryston is ripping off its customers? Okay then.
I don't remember writing that Bryston is ripping off its customers. Those are your words.
*************************************************
Lets look at a Bryston 4B cubed specifications:
Harmonic Distortion: ≤ .005% from 20Hz to 20kHz at 300W
Noise: ≤ -119dB @ full bandwidth
Slew Rate: >60V/µS
Power Bandwidth: <1Hz to >100kHz
Damping Factor: >500 at 20Hz (8Ω)
*************************************************
A quick look at a very reputable amplifier RB-1590 by Rotel
Harmonic Distortion: <0.03% from (20Hz–20kHz) at 350W
Noise:(IHF "A" Weighted) 120dB
Damping Factor: 300
*************************************************
Yep, that Rotel is a really nice amp, but do you see the difference in harmonic distortion and the noise A-weighting compared to the Bryston?
As I said, harmonic distortion specification along with noise is a mark of quality with regard to how the component will affect the signal passing through it.
Could you please direct me to the $100 amplifier you referenced that matches the Bryston specifications?
As I said before, components with identical THD+N connected to the same sources and speakers will sound the same. 2 + 2 = 4
The largest contributor to sound quality is from speakers and your room.
