I measured the CH Precision C1.2 with my Audio Precision SYS2722 system, repeating some measurements with the higher-performance APx500. The external power supply and clock weren't available for the testing. The C1.2's coaxial and optical S/PDIF inputs and AES3 input accepted data sampled at all rates up to 192kHz. Apple's AudioMIDI utility revealed that the C1.2 accepted 16- and 24-bit integer data via USB sampled at all rates from 44.1kHz to 384kHz. Apple's USB Prober app identified the C1.2 as "CH Precision USB Audio 2.0" from "CH Precision" and indicated that…
Soon I was exposed to heavy metal, during its golden era. I devoured it with the voraciousness of one of the demons on those album covers. Money I made from chores went right into the cash registers of my town's record stores. But unlike my friends, I wasn't satisfied with the big, obvious bands…
All the dealers I spoke to sell some…
As John Prine put it, "…

I performed the measurements of the Rotel RA-6000 with my Audio Precision SYS2722 system. I preconditioned the amplifier by operating it at 1/8 power into 8 ohms for 30 minutes. At the end of that time, the temperature of the top-panel grilles over the heatsinks was almost too hot to touch, at 130.4°F/54.2°C. The RA-6000 needs to be well-ventilated.
Looking first at the line-level analog inputs, the Rotel RA-6000's maximum voltage gain from the loudspeaker output at 1kHz into 8 ohms was 22.14dB for the balanced input and 27.8dB for the unbalanced inputs.…
