I have a VK31 pre-amp that I've used with ARC, VTL and BAT amps. (The BAT was a VK75, not the SE--which means I can play around with NOS tubes, which is fun with the BAT gear). That BAT combo was certainly synergistic. I would imagine you would be pleased, and I also would guess that the A'goners that are recommending the 60 over the 55 are probably right...if the 75 is basically the update for the 60, then you will probably like having a little extra testosterone with the 60.
BAT VK-60, VK-55 or ????
Been considering making the switch to a tube amp after borrowing a friends VK-55. It doesn't have quite the bass control my VK-200 did but "Oh does it have everything else". I have noticed the VK-60 is less expensive than the 55 but does it sound better than the 55? Or, are there other tube amps that don't run as hot and sound just as good for around the same price range? My preamp is a VK5i and speakers are Tyler Acoustics Linbrooks at 90db effiency. Thanks in advance.
