Tube Pre-amp BAT, ARC, EAR, Sonic Frontiers


Hello everybody
My system is:
Accuphase dp-57
Electrocompaniet AW120
Usher Audio CP-6381

I need a preamp. After reading lots of topics i marked personally: BAT, Sonic Frontiers, ARC and EAR pre-amps. Does anyone have any ideas which one could match better? Or maybe another suggestion?
Unfortunatly I have no possibility to listen to them in my system. EAR is an exeption. I will listen to EAR-864 tomorrow. But I am more inspired of SF and BAT.

I was auditioning Magnepan 3.6 to buy. The place was an ARC dealer. I took my Sonic Frontiers Line 3 modified by Chris at the Parts Connection,over $2000.00 mod, sounds better than the ARC LS25 latest. This was using ARCs equipment. I wanted to compare the ref 3 but they had sold it. I really like my Line 3. I also have the Sonic Frontiers Power 3 mono amps. They have 28 tubes so it nice to just call Chris when you need something. He is easy to deal with.
