Please Call For Price
Accuphase A250 – We only stock brands that we love at HFL so it was a pleasant surprise when I had an opportunity to listen to the Accuphase E-650 and instantly I was smitten, I have to say I was almost won over by the looks before it had even created a singe note, the presentation sounds just right though, honest but with a tad of warmth giving a very natural sound so if you are looking for a new amp, pre or source feel free to get in touch to arrange a demo of Accuphase.
Ultra-low-noise design with unprecedented S/N ratio of 127 dB brings out a stunning wealth of detail. Semiconductor MOS-FET switches enable output circuitry without any mechanical contacts. Two pure class A power units arranged right and left are driven in parallel to deliver 100 watts into 8 ohms with impeccable quality. A damping factor in excess of 1,000 means that speaker control is nothing less than perfect. The massive A-250 represents a new pinnacle in power amplifier history. Encounter music like never before.
