I hope there is somebody over there reminding them of the evils of opamp rolling
Why does Erji.net have such funny avatars compared to head-fi?
The O2 and ODAC are becoming all the rage in China now - http://erji.net/read.php?tid=1140434&page=e
Not so much 'burn in' as 'not burn out'. We took the military radios and put them in an oven and ran continuous Bit Error Rate testing on them.
To anyone in on the Front Panel Group Buy on DIYaudio:
Flynhawaiian stopped by earlier to test-fit the panels before sending them out to everyone. Fitment is cherry. Here's a preview:
The group buy panel is the one on the left.
Off topic...but what happens?
somebody stop me before I get funny ideas about a voltage divider network and capturing via a sound card line in.
Oh whoops I'm an idiot. It wasn't the regulator. I'm 95% sure it's just D4 (negative side 1N4002 diode) failed open. When my cheapie DMM is set to DC measurement, the claimed voltage across the positive side D3 is like 18V, while the same across D4 is a little under 19V. Sounds like a diode forward active voltage drop difference to me.
Will anyone be doing comparison tests with cheaper gear like the e5 or e6 or a well made cmoy (JDS, BSG, FredFred)?
If people are trying to prove that there is no distinguishable difference (or "improvement", whatever floats your boat) between the O2 and more expensive gear, it's only fair we go the other way as well.
