Ait, I also bought my first tube preamp - Supratek Chardonnay - without ever hearing it and it was simply impressive and fills my living room with beautiful music. And following expert advise from Ecclectique (thank you!), I replaced the stock with Bendix 6106, Brima 6F6G, Slyvania 6SN7 WGT NOS tubes. That was in late 2004; recently I received my Hyperion 938 and the experience just got much better!!! I am sure you would have the same experience. Cheers.
