Thiel 3.7

I auditioned a few speakers in this price range. Thiel 3.7 is my favorite. I have ordered a pari. I am think about the upstream for these speaksers. It seems although 3.7 has 91 db, it is a pig to drive. I have planned to use Bryston BP 26+14 B SST2 to drive it. I will use Ayre CX-7eMP as CD player, and use Cardas cables to make the whole system a little bit warmer and more musical. Can you please comment on this combo, and give me some advice?
BTW, I am wondering if BP 26 has balanced output. Should I use balanced interconnect cable, to make it sounds better?
Thank you in advance!
