Cheapest solution is acurus act 3 with ABM for around $500 range used. There won't be any cleaner more dynamic sound for DD/DTS for the money! There's lower signal to noise pre's out there however, but the ACt 3's more than liveable, and a veritable steal! You definitely won't find anything more dynamic or clear and detailed sounding for anything south of $1200 used
Processor for Av passthrough
I'm changing from a meridian based pre/pro to a 2 channel tube pre with av pass. I am in market for a quality processor to use. I'm looking at the sony 9000es, nad 761, denon 2802/3, etc. Recs. Any of these used will bypass the internal amp, instead using the pre outs into my tube preamp and cary cinema 5 amp.
