My 2 cents.. My system consists of: Mcintosch C2300 Preamp, 2 MC2000 tube amps, 1 MC352, JBL 4345,s Modded Khorns (alk xtreme slope crossovers, crites tweeter, alk trachorn, JBL 2470 drivers,solid silver wire)Basis debut sig, Vaccum tablr, Graham Phantom11, Van den Hul colibri's Dynavector XV1S. I've owned Sutherland PHD, sold it after heard the Manley steelhead 11, bought that, then got my C2300 Mac, (actually liked the phono section better than the Manley)! Then I heard the the Tron 7 reference...HAD to have it and DID! Not lookin for anything else, soundstage is awesome in my system. I usee Telefunken ECC803's, and ECC801S....
