I agree with Rinnie and Rod 1957. I have an Ultra SL hybrid pre amp w/o phono, two Ultra 350 hybrid power amps, an Insight bridge inverter with an Ultra Hybrid phono pre amp. Out of the box this pre amp was all that and some. I started with one Ultra 350 power amp I got from an Audiogon member that just killed my YBA Passion 1000 power amp. Being so impressed with the amp I ask Frank to build me an Ultra pre amp. I compared the pre amp using the Passion power amp then the Ultra power amp. The difference was like day and night. All the Alstine cost less then a fourth of the Passion 1000 power and pre amp's twenty one thousand dollar price tag. Thanks to member Alnozak for the introduction to Alstine eletronics.
