I got the new amp / preamp (Bryston 4B-ST, BP-25)
set up with the 1.2's and I'm getting no SDA effect, though the sound is clean and clear and very enjoyable.
A very strong center stage pressence.
I switched back to my yamaha RXZ1 receiver and the SDA is back.
But I find the overall sound less enjoyable,
I can't really describe it other than it's more fatiqueing to my ears, less velvety.
Any ideas as to how can I get the SDA effect to work on the Bryston set up?
