Tube Preamps.....

I would concur with recomondarions on preamps based with 6SN7 tubes. There is something special about this tube type, and there is (relatively speaking) a great selection of old tubes that you can roll with terrific sonic changes. Something SS will never do.

By all accounts the Don Sachs is a great one. I’ve have a Modright ls100, a Supratek. , and a Wyetech in my system. For my system synergy the Wyetech was the winner. YMMV.

Buying new with return / home trial is prudent. So is buying used at a fare price as you should be able to resell and not loose much. Good luck with your search!

For the best transparency without missing the best tube qualities (that are not always here when we have a tube item in hands): deep soundstage, harmonic developpement without dry signs, I would suggest  the Coincident Statement Linestage. I have one and could compare it directly to AR ref5se and my ex Rogue Hera 2, the Coincident is without doubt better than these two pretenders,  better transparency and fluidity. 

For a really good quality/price ratio, and if you don’t use usb input for your front digital audio gear (as the usb input is not up to date), you can find a second hand Ayon Skylla2 dac that is a dac with two 6h30 tubes per channel as output stage, tube retified, with three different gain ratio and volume control, so it’s a real dac with tube preamp inside. Beautiful association with solid state power amps that would be a bit too much on the solid state side of sound: excellent with Accuphase, too gentle for Passlabs.

I'm surprised no one's mentioned the Linear Tube Audio MZ2, a very fine little 6SN7 based preamp with separate linear power supply.  I got a Freya, and was quite happy with it, until I tried the LTA, and have not gone back (Freya for sale).  And that is before doing any tube rolling, which I look forward to.  BTW, well below your budget.

The original poster has not stated wheather or not he wants a phono section as well.. it makes a difference in price for sure.
