Bat Rex Mono Amps with Wilson Maxx II

Hi I used to have Maxx 2's (then Maxx 3's) and used the Maxx 2's with BAT VK150SE's and the Ayre MXR's

Before the 150SE's I had a VK60 and then a VK200.

I think you're loose some bass control with the tube amps. You'll gain some midrange purity...better decays...better imaging...typical SS vs tube differences. The BAT upgrades I did (VK50SE to 51SE, VK60 to VK75SE to VK150SE) where always worth while upgrades. I doubt you'll be dissappointed.

You really can't go wrong with your choices...one isn't right..one isn't wrong.

Honestly, I'd keep your BAT amps and try to upgrade to Maxx 3's. It's a significant step up. And if you buy used, shouldn't be a lot of money...

you can't go wrong with BAT/Wilson.

tube or SS is a personal choice- I prefer tube with your speakers efficiency, but some prefer SS and more bass.

There will be a trade off I had both the 600se and the 150se both were very good amps. With turntable the 150s just can't be touch, they just sound magical. But with the 600se you have some of the deepest bass that I have hear from any amp. That I have owe. At present I have the Krell 402e and that amp can't touch the 600se in regards to bass.
