***** No Longer For Sale *****__________________________________
For sale is a mint NuPrime AMG STA power amplifier. This is a current model. About two months old. Really stunning performance regardless of price, but super stunning for the price!
The AMG STA is the best choice amoung NuPrime's amps for folks who prefer the sound of all Class A design. It has a Class A front end and Class D amp section. It is the closest to Class A I have heard yet for a Class D amp. It is not a tube amp, but moving more in that direction than most Class D. Please read the website description and reviews to get more of a sense of this quality.
It is compact and built like a tank. It has a main power switch in back with a convenience switch in the front. 12v available power on/off. Either single ended (RCA) or balanced (XLR). Stereo mode or bridged for a monobloc amp.
Everything intact: amp, manual, factory power cord, double boxing for shipment.
List price is $1750. My price is $1250 - $50 shipping, without tax, anywhere in the US. Paypal f&f to avoid 1099. Check or Money Order with shipment after funds are cleared by the bank.
Long time audiophile with lots of trades. 480, 100% feedback on eBay. 100% on Audiogon and US Audio Mart.
