The Audiophiliac (Steve Guttenberg) had a review about the $10,000 Audio Research LS-28SE recently. He liked it better than his  Pass XP 30  reference (he still really, really likes the Pass, however).

these questions as stated are impossible to answer in any really helpful way

no info on system or room
no info on musical taste

waste of bandwidth

Benchmark LA4 is reference class if you do not want to hear the preamp. I do not want to hear a preamp.
