BAT VK 55 SE

I took a regular VK 55 home to audition. My speakers are 4 ohm so I hooked them up to the 3 to 4 ohm taps on the BAT. There was a channel imbalance, one channel was weaker than the other. I hooked up the 4 to 6 ohm taps and the channel imbalance got better. Must be something wrong with the amp, bad caps or transformer. The tubes are new. I'm going to try the SE version and see if it works. 

I personally have not lived with the BAT amps in my home or system but do have a friend that runs them in a near identical system as mine powering a pair of Wilson Sophias and they are marvelous amps, he actually had them wired to mono blocks doubling the power, which I felt was not needed. He has had them for probably 8 years with no issues at all. BTW, my amps in my system were MB125s with about the same power rating as his 55s after wired to mono.
 

tooblue, The dealer that I am possibly getting the BAT from is also a VTL dealer.  I used to work for the dealer so I get 25 percent off retail. Wonder I should go VTL ST 150 instead of the BAT? 

That would be a tough call for me in hindsight, but if you have a chance to listen to both amps in the same sitting, that might be worth your while. Enjoy the music

Much prefer BAT to VTL...
