  1. I think that there are advantages in using a computer as a transport, particularly if your CD's are suffering from rot. It should also be possible to produce a superior filter using the greater processing power of a computer, rather than that available in most filter chips. The actual D/A conversion is a different argument and IMO should be done in an outboard device containing a master clock used to synchronise the computer output interface, or via a buffered USB link.
  2. Peter, Thank you for persisting with me. You are quite right that Foobar on full volume is bit perfect. My problem was that the EMU0404 control panel is not. As soon I put a direct send insert in the ASIO strip the HDCD indicator on the DAC lit up! Thanks again and I will give XXHE a try.
  3. You misunderstand. I do not want "good sound" from the computer, I want an exact bit for bit copy of the data in a wave file delivered in spdif format. In other words, I want to use the computer merely as a transport. That is: a PC transport. None of the players I have tried so far will do this. If you know of a sound card which uses PCM1704 chips and tube amplification, do let me know. I believe that one advantage of ASIO is that properly designed player software can reconfigure the soundcard settings to suit the application. Not that it matters, as I am using XP, but can KS or WASAPI do this?
  4. Any more suggestions anyone? I am amazed that I still cannot find the pc equivalent of a CD transport. All the players seem to have a volume control and this is still, even when set to 0dB, a filter. There seems to be widespread misunderstanding of what bit perfect/bit transparent actually means. Many enthusiasts seem to think that avoiding the Windows processing is all that is needed, when it is actually the player which is the problem.
  5. Thanks for the suggestions. Looks like I will have to get to grips with Foobar. I have used it, but was hoping something with fewer options was available. I am not familiar with WASAPI or KS, so will do some reading. I am not quite sure how quality comes into it when using an external filter. Either the output is bit perfect or it isn't! My reference to storing in lossless format was just sloppy writing. I meant capable of playing an album stored in lossless format, as you guessed.
  6. Sorry I don't know what you mean by "my sig"? I am using synchronised SPDIF to an HDCD capable DAC. ASIO seems a good way to ensure a bit-perfect output to me, but I am happy to consider alternatives if there are any.
  7. Nobody has mentioned that you can get I2S from any soundcard which uses an Envy 24/VT1712 chip. I think one of the cheapest is the M-Audio Audiophile 2496. You have to solder to the PCB tracks, though, and it is a very fiddly job. It is then worth buffering and isolating the output with an IL715 chip. If you want to have a go, pin 72 is word clock, 78 bit clock and 82 is channel 1 data. You will need a good magnifying glass and a steady hand.
  8. Hello All, I am looking for a simple audio player which will store albums in a lossless format and play CD's. It must do bit-perfect ASIO and it would be nice if it worked well with a small touch screen. Windows preferred, but Linux would be OK. Is there anything out there which has not suffered from function creep?
  9. Probably a bit late in the day, but it seems to me that there are two main reasons why a PC would not sound as good as a cd player. As has been said, the first thing to establish is that the data from the PC is the same as that on the CD. I suggest that a good way of checking this is to borrow an HDCD DAC and play a file which has been ripped from an encoded disc. The HDCD light will only operate if the sound card output is a bit-perfect copy of the CD. The other problem is the SPDIF jitter. In my opinion the only way to eliminate this is to use synchronized SPDIF with the master clock in the DAC enclosure. A CD player with the DAC and clock in the same box has a natural advantage here.
  10. I am new to computer audio and want to use synchronised SPDIF with an E-MU 0404 sound card. Can anyone confirm whether or not a simple 64fs clock stream to the SPDIF input is all that is needed to lock the card?
