I recently sold my Sony TA9000es pre/proc on ebay. I'm considering either a new receiver or a new pre/proc to go with my ATI 1505 power amp. Many of the pre/procs i've seen are in the $2000 plus range, but it appears that there are several highly rated receivers that are in $1000-1500 range that many are willing to use as a pre/proc. What am i missing here!!
