Johnsonwu is correct. I recall it being a special package with the Spectral amps and special MIT cables and a 3D moniker. A class A amp like one of the offerings from Pass would be a good start. I also noticed an Audia Flight 100 listed for 3500.00 which is an excellent price for 100W of class A power.
Best amp for Avalon
Just bought a pair of used Avalon Radian HC speakers and wondered if anyone can tell me which reasonably priced amp would best suit the old classics. I currently have a Tube Research ST-100 but I just wonder if they would be bettered served with something else?? Anyone out there have experience with this speaker. Any input would be appreciated.
