Michael Yee amplifier and preamp - $600 (lafayette / orinda / moraga)

The amplifier and preamp are in very good condition.
To my ears, this amp sounded similar the Conrad Johnson MV-55 tube amplifier that I had owned.
I had both of these amps at the same time and I ended selling the Conrad Johnson.
The preamp is battery powered so it has negligible background noise.
If it will be used a significant amount of time, the two batteries will need to be replace every 5 to 8 years.
The 6V batteries are $22 per battery on Amazon.
The preamp was a prototype and a couple of inputs were mislabeled (as seen by the tape labels).
The preamp sounds similar to the Schiit Freya+ solid state section.
The Freya+ tube section sounds more lush.
Note that I am also selling a Freya+.
I can give a demonstration of these units with my Vandersteen 2C speakers and a Black Ice dac playing files from a laptop.
