Dbld, sorry about the lack of clarity on my post.
It was the Krell at $3999. Maybe it was the showcase.
I would guess you have the krell processor that was retailing at $8,000 at that time. If thats the case it should perform more then a $3,000 processor.
For 2 channel the D1 and avm20/30 sounds close from what I gathered. I was going to upgrade to the D1 so I asked several D1 owners who replaced their avm20. None of their responses concluded it was much different in two channel. My salesman also said the same thing.
