I run my Thiel CS 6 with Wadia A 340 Amps ( 500 into 4) and use the Wadai 321 Dac. I also run an ARC LS 2 MKII Pre Amp with a Cambridge CXC Transport MK II . I run Silnote Cables with MIT Speaker Cables. I have found that the more power you have the better the sound. Thiels are not forgiving with equipment so get the best you can get. Get good recordings to!
