I own:
1. Berning microZOTL
2. ASL MG Head OTL
3. HeadRoom Cosmic with Base Station One
4. HeadRoom Little More Power (Premium Module)
5. HeadRoom AirHead
The Berning is definately my favorite. The HeadRoom amps are clear, clean, and sound like solid state amps (which of course they are). The bass on the Little is a bit loose without the More Power. The ASL MG Head OTL is a bit tuby but enjoyable if you like a tube sound. I usually prefer it to the HeadRoom amps (I like tubes) and I have not had any problems with mine. You can get an idea of the sound of the HeadRoom amps at a reasonable price with an AirHead with a thirty day return policy. The folks at HeadRoom are great to work with (www.headphone.com). Good Luck.
