Used tube preamp $2-3K

I'm still pretty new to a CJ 17LS2 for a couple of months. Prior to that I had been using an Aric Audio Unlimited II in the main system. I have kept the Aric, as he no longer has it on offer, and because I like both the preamp and its tube collection.

The fun thing with this thread is that that the recommendations are great. If the right deal came along for a Linear Tube Audio, Don Sachs, Supratek, or Backert came along, they all seem like they'd be pieces worthy of trial.

If you are looking for remote, dynamics, speed, and transparency, maybe there's a Linear Tube Audio preamp in your future. I'd be happy to give one some shelf space for a while, without a doubt. Maybe others would fill the spec as well, or offer other strengths. LTA seems relatively uncommon on the used market, but so does Backert.

My Conrad Johnson is going to stay awhile, until the next thing. I just put a quad of Vokshods in for the ride.

+++1 for Aric Audio Super 6SN7 ($4,000) or Motherlode II ($5,400) and for Don Sachs/Lynn Olson Raven preamp ($5,500). 

I have never heard one in my own system (only in a fellow hobbyists), but the Supratek preamps are also excellent. They have a bunch of models from $2,500 to $6,000

The Backert Labs Rhumba Extreme (NOT the base Rhumba as it it not in the same ballpark in SQ) is also a great preamp at $8,500, as is the the BAT VK-80 at $10,000

I personally prefer 6SN7 based preamps (Aric Audio, Don Sachs/Lynn Olson, Supratek), as they seem to match my tastes best.....but the Rhumba Extreme and BAT were excellent using other topologies.

I tested all of the above preamps except the Supratek, and in the end purchased the Aric Audio Motherlode XL. I have since heard the Supratek Cabernet, and it is excellent as well.

I also want to echo the recommendation for Modwright LS100. 
I use a pair of Ken-Rad 6SN7 with mine and it’s fantastic. 
Another preamp that I use regularly and highly recommend is a Cary Audio SLP 98, also another 6SN7 based preamp. 
Both has phonos and I bought them used within the price range you’re looking for. 

Cannot go wrong with a properly cared for (maybe upgraded a bit) CJ.
