all I can say is:
If I owned an ET2 today....I'd be chomping at the bit to move to a 6922 and relay controlled volume setting unit. like ET3, ET5, GAT.
whether is was a smart move on my part, or yet another one of a thousand+ dumb moves, I discounted the ET2 immediately due to it's "chip based" analog switch volume control...and held on to my ClassicSE until ET3SE hit the street.
I had (have?) a long standing hatred of what we called at Ampex "IC analog switches".
Which I fully accept is rooted in urban legend and superstition more than reality.
having said all that, I'd love to hear YOUR report
on comparing ET3 to ET2.
