Mike,
Thx for your suggestion & clarification ... I agree the used market would be the way to go, I'll keep my eyes open.
I guess you know how much of a hasstle it is to upgrade [try & sell-trade,... have a closet full of snakes hanging from the coat rack] cables, so unless I am very lucky I will probably just stick with the Au pc's, as so far I find no real neg/or downside & am enjoying very much for what I paid which is always a consideration esp. for me @ the moment. I'm also using all AU24 IC's in the rest of my system,so as they say there is a synergy ;)
... but who knows, will keep an open mind when I can keep an open wallet, until then thx again, much appreciated for the suggestion.
