“This review is based on matching the Mini X with Hifiman He-500 Headphones. You may be reading this review, unsure what to make of this Amp, asking how can a cheap sub $200 amp offer the power needed for an expensive Headphone such as the Hifiman He-500? If you have done your homework you will find this is the stereo amp everybody is...” --fluidz
“I Background, gear used and manifesto I first got interested in the ECP Black Diamond around the time of its release. I was in the market for a “flagship” amp but still didn’t know what type of headphones I preferred: Dynamic, Planar or Electrostatic. While I’ve yet to hear an electrostat, I’ve found so far that I prefer the planars to dynamics. When I subsequently opted to go full-planar (for...” --Schopenhauer
“Addendum, May 2015: Since writing this review in late 2013, I purchased two other headphone amps, both considerably more expensive than the L-2. One of these amps is the Apex Teton. It deserves 5 stars for sound quality, as it is hands down the best amp I have ever heard. The other amp is the Eddie Current 445, which deserves 4.5 stars. Both the Teton and the 445...” --minimus

The DSHA-1 is a solid state headphone amp quite unlike any other amplifier on the market. The differential topology uses Lundahl amorphous core input transformers to provide passive noise-free voltage gain selectable to 6dB or 12dB. The novel MOSFET based output buffer couples to the headphones through nickel core output transformers, and the DSHA-1 can drive both balanced and unbalanced...
