Awesome system Pause!
I have the Andras' little brothers, the Fontaines (original version - with Italian granite sides) and have yet to hear a speaker I prefer more, except for the Andras, of course - love that eggy sound. I would LOVE to own them some day, but for now I will instead lust after yours and be satisfied with my Fontaines and dual external subs (selected specifically to mimic (loosely) the Andra woofers at 12" each).
Mine are driven with a pair of Audio Mirror 45 Watt SET monoblocks (parallel 6C33C tubes per) and the combination is wonderful - mid range to die for. Too bad you don't live near Atlanta. I'd love to compare the sound of our systems (Andras vs Fontaines + dual subs)- I think it would be interesting and fun.
I have been cable swapping like mad lately, looking for the (near) perfect combo. I will be interested in what you experience in your search. Depending on your musical taste I have a suggestion for you. You can e-mail me to discuss if curious.
