mini-X a-100

Stereo Flex Amp

The little monster.

Don't let its size fool you. The mini-X a-100 is a monster - the perfect choice for powering a compact high-end stereo system, a zone amp, or a desktop system. The possibilities are endless, limited only by your imagination.

We created the mini-X a-100 with the same design and engineering standards as our full-size amplifiers. The a-100 delivers 50 watts/channel of honest power - and it does so effortlessly, with superb sound quality and lively dynamics that will satisfy the most demanding audiophile. Along with its great sound, the mini-X a-100 has the flexibility you need, including a front panel volume control, trigger inputs and outputs, automatic turn-on, and buffered low level outputs for easy daisy-chaining.

Just because an amplifier is small doesn't mean it has to sound small - or be short on features!

  • Best-in-class design and sound quality - same superior, fully discrete design and high-quality parts as its big brothers.
  • Flexible turn on - audio sensing turn on or external trigger.
  • Front panel volume control allows you to use the a-100 as an integrated amplifier or control zone levels.
  • Heavy duty power supply with large toroidal transformer.
  • Temperature activated forced air cooling - put the a-100 almost anywhere.
  • Buffered loop output allows easy daisy chaining to more amplifiers.
  • Full sized 5-way binding posts make it easy to attach heavy gauge wires, lugs, or banana plugs.
  • Dual color, illuminated ring on the volume control indicates power, fault, or standby status.
  • User selectable AC line voltage; 115 VAC or 230 VAC.
