One stereo Nuforce HA-200 for sale. In excellent condition. Extremely good value for a Single Ended Class-A design from an innovative shop. With 2 of them, you'll have true dual mono balanced setup capable of 8W/ch. As a single stereo unit, like for sale here, it's capable of 2W/ cha.
Nice condition (8/10+), with SS front and black body; I can't see flaws. Excellent Class-A HPA sound. It sounds surprisingly smooth--crystal clear, but tinged some warmth. This is the only solid state amp I've liked with Beyerdynamic T-90. It has tube-like sound in the mids. Up to now, all I have owned are tube amps, except for Matrix HPA-1, which the HA-200 beats easily.
Shipping from 19380 at ~10 lbs. See my feedback under this moniker at ALL the usual places. Thanks and Happy New Year.
