I use an ED-1 with my Stax Omega earspeakers(vintage '94) and and SRM-T1 tube amplifier. As you may know, the ED-1 was designed for the Lambda series espkrs, but I find that they do balance out the midrange and clarify the base characteristics of the Omegas. It is easy to switch in and out of the circuit, and with some music I switch it out of the signal path, but not often and not for long. I am looking for an SRM-T2. Let me know if you run across one.
