  1. Interesting, a CD-ROM drive so old it has I2S. Can tap to send to a better DAC.
  2. That is a VST plugin, to use those you need to download the VST wrapper for foobar: http://pelit.koillismaa.fi/plugins/show.php?id=213
  3. My statement was directed at TS's case of the sound card being unable to drive headphones properly. For your case you might want to check with this: http://www.thesycon.de/deu/latency_check.shtml
  4. Maybe your laptop's sound just lousy.
  5. What you should be checking is whether turning the pot has any effect on the signal eventually reaching the amp chip. Place your probes on pin 5 of the chip and this pin on your pot It should read 10k at min volume and ~330 at max. Also, the two topmost pins of the pot (with respect to the diagram), check that the resistance between them is zero regardless of pot position. This could be just a simple case of broken solder.
  6. Do let know the outcome, thx.
  7. What you described is a quite common occurrence for USB DACs - a power surge from turning on/off something else knocks out the DAC and you need to cut the power and on it again - which disconnecting and reconnecting the USB cable does. IMHO a well-designed equipment shouldn't be affected by this, but seeing many anecdotes of this happening and owning two DACs with this problem I'd say this is pretty normal. Maybe your stereo amp and headphones are just too powerful. Add: It's possible both ways - that your unit is more sensitive or it happens across all units, if in doubt test with another unit.
  8. A few years for it to get noticeable. ESR starts to increase, then capacitance drops.
  9. I posted before; put in normal case (jewel case) and throw in envelope. The receiver was to burn and perform error scans on the DVD+Rs in question and he did not note anything abnormal.
  10. AES/EBU is either 110-ohm shielded TP or 75-ohm coaxial. It does not use 110-ohm coaxial.
  11. 1) Google 2) The 75-ohm coaxial cable "standard" (IIRC it was never really defined but just followed for convenience) is used in phono, composite, component, and SPDIF with RCA connector, and used with many others with other connectors including TV, AES/EBU, and ethernet.
  12. Most if not all RCA should be 75 ohms, analogue or digital, video or audio.
  13. KOK is one of those brands "you can find being sold here but you'll never find its info nor its manufacturor's info". The name is probably a mimick of KRK? I dunno, but they also produce audio switches and mixers so I don't think they're a small wannabe company. Don't expect them to be very expensive.

    Ok lar, at 0.3A current draw to drop 5.7V will only result in 1.71W, doubt you'll need a big heatsink for the LM317 if you're using TO-220 package, or just screw to case will do. If you got the TO-220 version that is.
