Here's a beginner's review of the SInglepower MPX3 headphone integrated amplifier. The reviewer, to his credit, comes out in the beginning and says it like it is:

I had never reviewed a headphone amp before having the opportunity to spend time with the Singlepower MPX-3.

So as long as you're not a hard core headphile coming into this expecting an in-depth analysis of the MPX3, this is, in fact, not a bad little review for those just getting involved in the high-end headphone craze. For those looking for hard core prose, who better than 6Moons to give it to ya. Srajan compares the Singlepower MPX3 against all kinds of headphone and regular equipment to arrive at a Blue Moon award for tubed awesomeness.

The Singlepower MPX3 starts at $949 and goes up depending on tweaks. The MPX3 falls in the middle of SInglepower's pack with the $649 PPX3 at the bottom and the $9000 Maestro ZR at the top.
