Best Used Tube Based Preamp $2k Or Under?

I would go used.

As far up the model level you can go. No more than ten years or so old.

@nightfall Thanks also to those who have recommended Cary SLP-98’s, another unit I was considering, though they seem to be selling a bit over my $3k limit. And the Modwright LS100 is also a great recommendation you provided. I once owned one, and would have no trouble buying another one.

I wonder what you decided about moving beyond the MW LS100 and why - if you don’t mind the ak? I’m a happy Cary SLP-98 long term owner, and also enjoy following Dan’s designs for MW too. Good stuff. Like hearing from MW owners.

Looking back some I see Dan used/shipped some of the exact same OEM 6SN7 tubes I've used in my own 98 preamp.  Can share my own preamp is hyper-sensitive to the different 6sN7s I’ve tried in it. Tried more than a few.  Wondering why you moved on and what tubes you tried in our LS100 if you don’t mind sharing more as you seek another preamp.

If your budget is as high as $3k I’d look for a Conrad Johnson ET3.  Only takes one tube so you can roll til your hearts content to get the exact flavor you’re looking for.

If you can find Tsakadiris Alexander preamp buy it. I got mine at TMRaudio.$1100 . 

There is a Cary SLP-98 on US audio mart right now for $2000usd. It's an older posting.

I find the Cary SLP98 usually prices at $2000 - $2300 depending on upgrades.

Not many VTL's get posted in the used market. I guess everyone is happy keeping their VTL, like myself. :)
