Big thanks to my brother Tom for extended-loaning me a tube amp and pre-amp to compliment my superb already on-loan Advent 300 and 70's vintage Infinity speakers (unsure of the model number on those). The only thing I know about these new pieces is that they are hand made by a small company called Nobis Technologies from Wisconsin, that they are very heavy, put out serious heat and they sound and look fantastic. (note on the picture, the bottom right is the back of the pre-amp, the other three are just different angles of the amp with a night version showing how the tubes glow)
