I have the same headphones and amp. They are very revealling, and if anything on the front end is at all harsh--you will hear it. I did use some Audio Purist interconnects, which I feel tame them a bit, but it is still right on the edge. These are not polite headphones, they are used in the recording industry because they do reveal so much--kind of double edged sword.
Stax Lambda Pro Headphones--Can sound Hard??
I bought a used pair of Lambda "Pro" phones with SRM 7 box. They sound very good and generally better than every dynamic phones I have tried, but also sound a bit "hard" in the high frequencies,. I only occasionally use them, so I don't want to sink any big bucks into "mods" or expensive interconnects. I have them wired to a McIntosh 1700 receiver speaker outputs to avoid hooking the transformer box to my amp. I also have a cable running (Audioquest "Coral") from my preamp to listen to CD, tape and Turntable. Any suggestions on improving the overall sound, and eliminating the "hardness" Thanks, Jim
