FWIW--I had a Audiogoner tweak my Adcom preamp and was totally satisfied with the results. He can be e-mailed at Ardillas806@aol.com for the specifics.
adcom 565 preamp question...
Well folks...picked up a used one at a fair price recently...quick question...on the pre-outs on the back...one is labeled "lab"...is this the passive connection? there is also one labled "norm" and one "direct" (which doesn't sound as good)...thanks...
