Spectral recommends MIT cables for their equipment. While some people have used other mfg cables, this is an area of concern you should consider before purchasing Spectral. I also find their equipment a little dry and not musical to my ears (my opinion). I suggest you go listen but ask about the cables.
Spectral Amp
I am think about purchasing Spectral Amplifier. My concern is that I have Mark Levinson No. 39 CD Processor, which can directly drive the amplifier. I currently drive my amp with ML No. 39 (CD is my only source). However, the dealer has suggested that Spectral Amp has to be mated with Spectral Pre-Amp or else the amp will blow up. Any thought or suggestion on that. One more thing, if ML 39 cannot drive Spectral, can Wadia CD Player drive Spectral Amp?
