Freeflap - If you got better results from a cable, just wait an see what an amp can do. I am using Alpha Primes, with my Lyr 3 on high gain with KenRad tube, and they are sounding glorious. I can only imagine that all of MrSpeakers headphones sound great on the Lyr 3, no matter what cable you are using.
Another update: i found a lightly used Lyr3 on ebay.. and bought it. It arrived Saturday. it has the multibit USB card installed and it came with the TungSol and the LISST. So far, i have not tried the LISST yet, but am enjoying the amp very much.
Initially, I was not impressed with the sound vs my jds element. it was very similar. however, after 24-48 hours of burn, it has opened up greatly. the sound is deep rich and smooth. The ether flow no longer sound dark. they have opened up and very musical. no etching in the treble, but very clear and detailed. All three of my headphones sound better with this amp: monoprice m1060, ether flow, and LCD2.
Need to spend some more time listening but so far am happy and suprised that it has made such a noticeable difference.
