Preamp under $2,000 used

My favorite preamp is from Don Sachs.  It is by far the most musical preamp I have ever had.  I previously had CJ, HK, Berning, Modwright, Belles, and a few others I know forget, and the Don Sachs preamp is clearly the best.  

Owner of both Don Sach's DS2 6SN7 Tube Pre-Amp and Kootenay KT88 Tube Amp; an Outstanding combination that evokes a life-like performance in your listening 

Definitely the Ayre K5xeMP, basically the latest iteration, though it may be a bit above 2K used.

To add to that, I own the Ayre k5xeMP, and I love it. It has an open, smooth sound, maybe a touch of sweetness, has one of the best volume controls I have ever had the pleasure of using. Fully balanced, dead quiet. Replaced a Dehavilland Ultraverve 3 and is better than it. Though I may soon put it on the market as I am very happy with my new tube integrated and I am not planning to keep my SS separates.

Well after much deliberation and looking for good deal on used preamp I found an Ayre K-5x it it sounds fantastic! Whole new level of refined sound, much sweeter highs and more extended  Vocals are very smooth and natural. I notice pianos, horns and live music sounds much more realistic.Live guitars sound like you are there in an intimate live setting, just amazing when listening to Dire Straits live. 
Now waiting to trade RCA interconnects for XLR for the next step up and better gain, Ayre recommends XLRs for best sound. I'll report back.
