I do not understand why spectral has a following my self!, Years ago, the late 90s,1997, I took the spectral amp out of a licensed spectral system and installed a Krell fpb 600 amp and took the mit cables out too!, installed Taralabs the one cables thru out,along with the Krell that was on the Avalon Edilon speakers, I was floored by the sound with the Tara cables and Krell amp combo with the spectral pre-amp and cd-player, this was a game changer!, ever since then, I have bought Krell amps!
