What Audio Research preamp would be an upgrade to my LS2B

Do you have a mk1 or mk2 Ls2b and what is your budget.

Audio research has several upper model preamps it depends on how much your willing to spend.

There is lots of other brands also unless you want to stick to AR.


Best of luck to you,

Kenny.

I moved from an Audio Research LS2B to an LS25 mk2 and the difference was huge. I have now moved to a Ref 5se and again the difference is huge.

 The LS25 mk2 is really a  nice preamp, Very detailed with a large 3 dimensional sound stage. It would be my suggestion unless you can afford a Ref 2 nk2 or Ref 3.

Kenny,
I always liked the ARC products and I am happy with the LS2B but the bug has me wanting more? As far as budget I will pay for the right fit. The LS2B is the Mk 1

Lostbears,

It was from someone like you that I was looking forward to hearing from. Thank you for your input because you know the LS2B and made the move. I haven't heard the LS25, but you say it is a big improvement Oh boy!

 Take a listen to the new LS 28 I have compared the various ARC line stages over the years although always decent the latest group ac-cells well beyond what was ten years ago or even more recent years efforts.
