I am using the H2o Signature Monoblocks with the First Sound Presence Deluxe Mk II and am very pleased with the synergy. There is a review of the amps on http://www.6moons.com if the amp is of interest to you...
Question for First Sound Owners
I currently have a first sound deluxe mkII. I'm thinking of replacing my Jadis DA-8 amp. I recently tried a conrad johnson amp and they did not match. The sound was congested and lifeless. I have heard the CJ amp sounding good so I guess this is more of a matching issue. In this regard, i'd like to know what amps you guys are using so i can avoid purchasing something that will not match the FS. TIA.
