Help me decide


I need your help on deciding which preamp (just for 2 ch music) will be the best for my system that basically consist of:
Integra DHC-80.1
Emotiva XPA 1's
Tyler Acoustics D1

The options I'm considering are:
Wyred 4 Sound STP/SE (new, with HT Bypass)
Marantz SC7 S2 (used, no HT Bypass)
BAT 51SE (used, no HT Bypass)

Thanks for your help.

I would choose the BAT. Build quality is as good as anything else out there, As far as sound quality goes, I can't imagine you not liking it. If I were you, I would also consider Ayre and Aesthetix. Both are extremely good products and are in the same league as the BAT. All 3 will sound great, but different from each other.
