These are the "Lite" version of Fred Volz's fantastic Vita Amps. They won best of show at the Rocky Mountain Audiofest several years in a row. They have a lighter aluminium chassis than the regular Vita's and unpotted transformers, but use the same circuit, are nearly as powerful at 50+ watts/channel, and share the same house sound. This pair was originally sold in 2013. I have original boxes for shipping and they are in excellent condition with the exception of a 1mm long scratch on the top of one of the amps. Tubes included are 4 - 6550 GE's, 4 - 5687 Philips & 4 -5UGB's RCA's. All NOS with reasonably low hours (I have not been doing a lot of listening ... the main reason for the sale). I have some cryo treated matched KT-120's I purchased from Upscale Audio I can make available at a good price as well as 8 extra JAN NOS rectifier tubes, if you are interested.
