I'm not sure what to think... From my moniker you might think I'm into tubes...and I am. Yes this a saucy little piece of equipment. As near as I can tell, the structure of the amp will likely yield a good balanced sound as far as tube amps go. On top of that, my first headphone amp was the Little Dot MT (Micro Tube). I selected that one, because the design and construction showed a great deal of respect for the sound. The power "brick" wasn't a wall wart. It was a substantially designed power supply isolated electrically. The construction was very good. All-in-all, I really liked the unit. It sounded good, tubey and with a healthy amount of authority. I'm now projecting this experience onto the amp offered here. I fear I can't be objective. Quick somebody, list some real world comparisons for me.
