So am I right in saying that to use the Sophia or KR  PX-4 with the BA, all you have to do is change the voltage from 5V to 4V?

I thought the switch in the back controls whether the preamp outputs are RCA or XLR?

Are there any general statements that can be made about the sound of px4 v 300b?

The EAT 300B compared to the KR PX4 have better defined mids and smoother lower end.

Together with the TS BGRP they make the SR325is sound excellent.

Don't you get the Western Electric 300b with the amp? TSRP, are that good.

Actually, it turns out I only get JJ300b due to a misunderstanding (which I guess partially explains the low price).

XXII you got an excellent deal, if I known somebody was going to sell their BA so soon so low I would have waited for sure!

And yes the TS BGRP are that good!

Just make sure you get a nice, strong tube, you won't be sorry.
