We Think Our Products Are Great
We are intelligent Engineers designing intelligent products. Much thought goes into everything that comes from our design labs:
  • Audio Quality: The audio quality of our products is rock-solid; no detail is overlooked: Military-precision feedback resistors. Oversize tantalum and electrolytic capacitors to create ultra-stable power planes. Impedance-controlled circuit boards. The list goes on. And we are one of the very few manufacturers who actually publish audio test reports for our products (see here, for example).

  • Spectacular looks: We design our products to look great. Take our new XM6, for example: with its glossy anodized faceplate and compact robust elegant package, it looks absolutely gorgeous.

  • Functionality: We include every feature you'd need in a headphone amp: Bass boost? Got it. Variable Crossfeed? Got it. Auto Power-Off so you don't accidentally leave it on and kill your battery? Got it. Built-in battery charger, low battery indicator, DC power jack? Got it, got it, got it. Again, the list goes on. And now, we're offering a great Lithium-Ion FastCharge battery system as an option. No other amp has all these features in one package.

  • Ergonomics: All buttons, knobs, and controls are well laid-out; the main volume knob, power button, LEDs, and input and output jacks are all on one end of the unit, allowing the amp to easily be carried in a pocket. The case and internals are machined to give a snug fit, with no rattles or loose batteries. Not only do we sell amps, we use them ourselves too.
