I also wonder on the 3 if it has a nostalgic reference to Eng Chris Russel 1st product of Pro3!!
However,
Manufacturers have a challenge to provide an amplifier with such a transparency to reflect the currently available high resolution input signals.
Such signals were not available to us the consumers until few years back.
I, now believe that through the term New Circuitry, Mr Tanner has also pointed to a new mother board.
In the world of the now very affordable Personal computers, such competitively priced quality was only made possible with linked integrated circuits that are simpler to produce while economically viable.
Looking at the Bryston product development in the last few years, there was a significant leap in the area of input signals programmed filtering.
Now it’s the turn of the Bryston Amplifiers to benefit from the above. So I think.
Thank you
