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.

yes with each change there is a jump in performance from normal to se to se+. more transparent, better bass definition, lower noise level...
Snarkonmars, If you are looking for balanced tube preamps, I would think your short list would look a little different. Am I missing something?
Hello Atmasphere

at the start balanced preamp was not that principal. But now I am on balanced connection so....
BAT, SF, EAR and ARC are in short list anyway

I am more on SF line 3SE side to say the truth
Snarkonmars, I don't think SF ever made a balanced preamp, although they have the connections. At least I say that in the context of being fully balanced throughout, like our preamps are.
