Hi Kabaraka, I just replaced my Eklipse with a Concert Fidelity CF-080 which costs $15000.00 more then the Audio Valve piece! I had auditioned scores of preamps, including the Calypso, and found the Eklipse to be better in its sonic performance or at least as good up to $12000.00 units. For details on the Eklipse and what tubes make it "sing" take a look at my Gon review. Hope this helps.
