Went back to it's owner last Friday. However, today the replacement showed up, and it's MINE!
Mine's black.
It's even quieter than the CAT. In fact, no hum at all. A hybrid, after all.
Frequency response ± .5dB, 5 Hz to 50 kHz
Distortion (THD) < .01%
Noise & hum 100 dB below 1V RMS output
Not the "magical" sound of the CAT but excellent nonetheless.
Happy again.
