recommendation for office rig
I would appreciate any recommendations for a sealed, over-ear, isolating headphone to be used in a relatively quiet open office setting. Priorities in decreasing order are sound isolation (including keeping sound IN), comfort for hours of use, price, and sound quality. I don't like IEM or on-ear...- eweitzman

uDAC-3, innovative NuForce technology delivers highest-resolution audio for ultimate mobile sound.
Can you describe the data at the coax output? In the case of PCM, is it the original data received by the USB connector, or is it resampled, or something else?? What about DSD? DoP, or PCM, or something else? Is it affected by the volume control? - Eric- eweitzman

How to change LED light on LD MK III?
You can buy vinyl electrician's tape in multiple colors now, not just black. Get some white tape and put one or more layers of it on the LED. It's a bit translucent, not totally opaque. I found one piece of white tape on my Benchmark DAC1 muted the intensity of the blue LEDs just the right...- eweitzman

Ted, IIRC, the RATTV3 report file is re-created automatically after each run cycle, about every 3 minutes. The report is created in the %SYSTEM32%\logfiles\rattv3 directory. Check the README file in the RATTV3 group in the start menu to be able to interpret the report. For example, the report...- eweitzman

Here's my email to Elias from March after I solved the latency/pop mystery on my five year old IBM X22 laptop. The procedures involved apply to Windows XP only AFAIK. - Eric Code: Elias, I have great progress to report. Complicated, but great. I can use the DAC1PRE with my old IBM X22...- eweitzman

furball, PCM refers to how data is encoded/represented: as 16 bit (or 24 bit, etc) periodic samples. The S/PDIF and AES3 transmission standards carry two interleaved channels of PCM and some control info, but their two channel nature is not a limitation of PCM. ADAT carries 8 channels of PCM...- eweitzman

You're correct in what you're saying, but there's more. Just think about mp3 playback for a minute. Two channels of stereo are encoded into 32 or so low bitrate, frequency-limited channels. Possibly with joint stereo processing that collapses some channel pairs into single channels. Or flac...- eweitzman
