You don't indicate a price range, but if you're looking for something in the $1500 +/- range, check out the Raysonic 128. Well built and tunable by tube selection. Got a good review in 6moons. Their only, possibly negative, comment was it was full in the bass, not bright and not as transparent as the reviewers reference. That issue is resolved by simply changing the tubes! Those traits are more the result of using EH tubes than the unit itself, IMHO.
