I have owned the both the XP20 and the XP30 and yes, they both were anemic(a description that I have used several times on separate threads), and un-musical in my set up...and they were feeding Pass mono amps to boot. He makes fantastic amps, but the preamps are underwhelming to say the least. I went to a tube preamp(Aric Audio Motherlode) and never looked back...a great pairing with solid state amplification! Ditch it!
