I had Sophias, now WP7's, and ran them for a while with the BAT VK-500, then VK-600. Great bass and dynamics but no soundstage. My recommendation would be an ARC VT100 Mark III or Conrad-Johnson Premier 140. You will lose a little on the bottom end but gain so much soundstage size and improved tonal balance that you will wonder why you ever tried the BAT solid-state equipment. Or if you ever see some used Essence solid-state amps, they are the best I have ever heard with Wilsons. I am not sure what you are using for a preamp, but a tubed job like CAT or BAT or ARC will also greatly improve the sound.
Upgrade suggestions from BAT VK-300xSE
I'm looking for advice on an upgrade from my BAT VK-300xSE, without breaking the bank. I'm considering Audio Research LS25MKII & 300.2 or VT100MKIII (used). Or BAT separates, but I've been told; that I'd have to go way up the line to better their Integrated by a significant margin.
