Audio By Van Alstine DVA M225 mono amps

The May/June issue of The Absolute Sound gave them a terrific review. One of my friends is using older Van Alstine amp and pre with his Philharmonic 3 speakers and the sound is awesome. AVA has been making well regarded audio equipment for years.

Heard great talk about AVA, even heard positive about their customer. Service. 
 

  Very basic designs, which have good reliability
