Working excellent.

Long before Levinson, Krell, Threshold, and others, there was CM Labs of Danbury, CT. This little high-end company produced some of the most musical solid-state power amps. The build quality is robust and it is a total mil-spec amp. The 914 is one of the first,if not the first, high-speed power amps.

The power output is 125 Watts RMS into 8 ohms, with less than 0.1 percent THD, at any frequency from 20 to 20,000 Hz. 175 watts RMS into 4 ohms. IM Distortion less than o.1 percent up to rated power.At full power, frequency response +- 0.1 dB from 20 to 20,000 Hz. The damping factor is better than 500 at 8 ohms!! The circuitry is fully differential, the fully complementary common-emitter output is built to MIL-spec A8625C, Type 2. More important than all the above impressive specs, is the sound quality.
