BAT or Levinson

I'm in a similar conundrum. I also have a BAT VK-60 driving AP Virgos and there is also nothing wrong with this setup. But the one thing that keeps disturbing me is that small amount of noise coming from the BAT. It's not an issue when music is playing, but when it's very quiet in the house and my ears are in good shape I can even hear that noise in the listening position. So, for a while I was entertaining the idea to get some other tube monoblocks (although I totaled the car this weekend, so no upgrades for a while). But the VK-75SE would also be very tempting. Jfrech, since you mentioned the 75SE is a bit more quiet, how much of a difference can I expect? I guess, I wouldn't be totally quiet, would it?

WOW..i see that the Bat VK75se go for 5k used.hmmmmmmmm..wonder which is better.. purchase another vk60 for about 2k or sell the Vk60 and invest another 3k for the VK75se??..the pre i am using right now is the Bat vk3i and EAD ultradisc 2000 cd player.

I owned a ML 331 and although it was a very nice amplifier, I found it to be a bit dry and somewhat sterile than my Audio Research VT-50 or VT-100. If you are going to go with Levinson I would recommend the 334 which replaced the 331 a few years back. I can realte to you wanting to try different amplification in your system and you rightly should....I am just not so sure you are going to gain anything with the 331.
