Very nice system and you are one of the few that has Spectral gear.
I am thinking of making same changes to my system and the first would be to get a new preamp. The Spectral DMC-30SL has come very highly recommended by my Audio retailer who does not carry Spectral (no dealer within 1500 miles).
Any thoughts on the preamp or their amps.
Everything that I have been able to read has been positive.
Thanks for you time.
