I'm using the First Sound with a Music Reference RM-200 tube amplifier with excellent results. I feared the low input impedance of the RM-200 (15kOhm) would be a problem, but it sounds great to me driving Hot Rod Shearwaters.
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.
