Purity Audio Design Reference Preamplifier--beautifully sounding preamp utilizing 6SN7 tubes and tube rectification. Multiple upgrades bringing the sound of this preamp very close to the much higher priced Purity Statement series preamp. Tubes are low hours and I will include 2 sets of NOS tubes with the purchase. Only selling because I am downsizing my system. I will cover shipping and insurance costs in CONUS and PayPal fees. Please also see my add for the Purity 300B Ultra Mono Bloc amps. I will offer a package price if interested in the preamp and amp combo. Thanks for looking!
