Superb Nelson Pass design based upon his Stasis amplifier design exemplified by Threshold Corporation. This is the PA5 rated at 100 watt per channel which is enough STASIS watts to drive any speaker, these even drive the Martin Logan ReQuest electrostatics that dip to just over 1 ohm, with no problems whatever. The sound is crystal clear and ethereal and has a very good bass rythm and drive. I am happy to demonstrate the amplifier driving Sonus Faber speakers. Any questions or queries pop me a question via the ebay messages- more pictures to follow
