Opinions on the synergy between BAT components

I owned a vk500 with I traded for vk60 monoblocks. For starters the vk500 is a very big and heavy amp which doesn't fit easily on a rack. It has a natural tube-like sound, is very quiet. Nice overall tonal balance, but has a drier sound than the bloomy vk60's. They say it sounds much better with aftermarket cords (needs 2). I used it with a vk5i so it definitely would handle a better preamp.

I have a BAT VK200 that I use with a BAT 30SE Preamp. I had an Audio Research LS 25II when I purchased the BAT amp. There is no doubt that with the BAT VK200 the 30SE is superior in almost every regard. I believe that this is due to synergy between the same companies components, not necessarily due to better better build quality, technology, ETC. I would expect that the Audio Research preamp would sound better than the BAT if the amplifier was an Audio Research VT100.

I am told that the VK200 is a better sounding amplifier than the VK500 in situations that do not require the additional current offered by the VK500. If your Hales are reasonably efficient I would suggest you listen to the VK200 before you make your final decision. Good Luck

Dave, there is very good synergy between BAT preamps and amps. I own a Vk-60 and currently have a 30SE pre, but had a 3i when I got the 60. Though you can get good music by mixing brands, I think you'll be better served by BAT synergy. With your Hales, you definitely need the ss power of the vk-200. The 500 is mostly just a bigger 200, though it is dual mono, complete w/2 pc's needed. Good luck.
