Tubes Asylum: REVIEW: Transcendent Sound Super Compact 150 Amplifier (Tube) by mike b

Bottom line: If you are in the market for an amp with plenty of low end punch, clear, clean extended highs, and ultra-quick transient response, you should give the Super Compacts a listen. The presentation is a bit forward, but well balanced, accurate, and detailed without a hint of harshness or grain. They handle both macro and micro dynamics with ease due to their quickness.
I consider myself a bit of a tweaker, but since purchasing these mono-blocks, I have lost the urge (at least tweaking my amp). Taking a peek under the hood, you will find excellent build quality, no designer parts, but good quality parts nonetheless. Although I have not tweaked my Super Compacts, I have done some tube rolling. I replaced the stock 12AU7s with RCA clear tops, and the 12AX7s with Raytheon 5751s. I also tried RCA grey plates (5751s) in the 12AX7 position, but I prefer the Raytheons

In summary, I highly recommend the Super Compacts. These are not finicky amps, No matter what your musical tastes, or speakers you will be driving, these mono-blocks are likely to deliver the performance you want. One would be hard-pressed to find a better price/performance ratio. Bruce Rozenblit is almost giving these babies away. Furthermore, I prefer directing my audio dollars to small companies and dealing direct with the designers.
