Hi Maria, I am currently auditioning an Audio Valve tube preamp in place of a lexicon MC-12B pre-pro, and the difference between the two is quite noticeable. The audio valve eklipse is a 2 ch. preamp, and it seems to be a fantastic pre. Thats Audio Valve, not valve audio. Although that is probably a fine piece as well. Anyway, i beleive i will be going with the A tube preamp for 2 ch. listening only as i will keep the lexicon for video in which it does a fantastic job with. Good luck.
