Dtanclim, you've got some serious stuff there, that deserves some serious, quality, electric. Plug your Concentra into an Audio Magic Stealth, or better yet, the Mini Matrix (I think Jerry is making them, now) and plug your digital into the Stealth Mini Digital. Then get back on the 'gon and tell us about your new system. It'll kill ya. If you're interested in purchasing one I can turn you on to the dealer I purchased mine from. Great price and service. peace, warren
