Which used preamp for Halo A21, under $1,000?

I was surprised by the YS audio preamps The prices were very reasonable. It appeared to be a 12AX7 design (not sure), I wondered which tubes needed to be changed. Although I put old stock tubes in my gear where ever it makes sense.

Daniel825 and Mechans: Which YS Audio preamps have you both used? I see there are a few different models.

Agree with the Muse Model 3.... excellent, single ended, balanced and remote.... Look for the 3 Signature, an upgraded version, should still be had for $800 to $1000

I am still using the YS Audio "Symphonies with remote model" I sold my Parasound A21 along with the Maggies a while back. I probably would not have sold the A21 but the guy who bought my Maggies wanted the amp also. I am now using the YS Audio Symphonies tube preamp with 2 rotel amps run in mono. I have bought and sold a lot of equipment in the last few years but I won't sell the YS preamp.

Thanks Dan. What other preamps have you used that you can compare the YS Audio Symphonies to? Where do you think it comes up short?
