Spectral, Avalon, and MIT used to market a system they called 2C3D, using Eidelons with Spectral amp and preamp amd MIT cables. I don't remember the source but I would imagine Wadia would be as good as any. 2C3D stands for 2 channel, 3 dimensional.
I had my ear talked off about the synergy between.
Eidolons, Spectral amps and the Wadia 861SE. Are they really that good? I have no plans to move away from the Merlin sound anytime soon ...if at all.
