is BAT good with non-BAT components?

I have a BAT CD player linked to a UNISON Mystery One pre-amp and a pair of UNISON Smart 845 SE power amps driving
Von Schweikert VR4's. They were not purchased at the same time but seem to work very well together. I did upgrade the tubes in the BAT (Upscale Audio) also the BAT is somewhat power cord sensitive. Fat Man and Fat Boy work best for me.
Good listening,

I have heard from my dealer who sells, both VTL and BAT that they are not perfect mates. However, BAT does match up good with other stuff. I've used Wadia CD players both w/ and w/o bat preamps, with a VK200 and vk60. Currently running a muse 9 sig cd/dvd into a bat vk50se/vk60.

just my take...

I am using BAT VK-50SE with Theta Dreadnaught with great results. No problem whatsoever.

There is nothing wrong with using all BATs. Everything they make is exceptional.

I am using a BAT VK5i SE with Aronov monoblock amps, a Muse 9 Signature digital front end, Linn LP12/Linto analog front end and Sonus Faber speakers. Works like a charm!

I just recently upgraded to a VK50SE preamp (Which blows away my old Sonic Frontiers Line 3) and it matches up beautifully with my Mark Levinson 332 amp and 360S/37 processor/transport. You shouldn't have a problem.
