Unison Research S6

After owning over a dozen audiophile integrated amps, the Unison Research S6 has been one of my personal favorites.

This S6 is in great condition, is beautiful, and has been 100% reliable for me. Tubes are the originals, and are still performing like new. Have had it connected to both high and medium efficiency speakers with great success. My favorite combination has been the S6 with Audio Note AN/J standmounts.

The S6 is a current offering from Unison Research and lists for $5,999. I’m asking $2500 plus actual shipping charges. Buy with confidence from a 20-year plus Audiogon/US Audio Mart member with perfect feedback. I accept cash, personal check (remember those?), and PayPal F&F. Don’t hesitate to contact me if you’d like more details Thanks
