I was fortunate enough to be part of the Sangaku loaner from the very kind Todd from Todd The Vinyl Junkie. Right up front this is a $2,000 amp, my expectations are high. Listened through my usual source, Gumby and Mutec MC1.2 DDC.  I've been a Pete Millet and Apex audio fan for a while, building several of project on his DIY site. I was quite excited to try a high end tube amp using a new type of tube, the Korg NuTube. The Korg Nutube runs cool to the touch, lasts 10,000 - 20,000 hours, and cant be rolled with other tubes (yet?)...
