ASIO on PC & Mac with iTunes & Apple Lossless


Ignorance is bliss and I was too stupid to know it. I did an A/B test with my CD drive optically connected to my DAC1 and computer/waveterminal connected to the coax port. All my music is in iTunes ripped with Apple Lossless Codec.

The DAC1 has a nice little switch that allows me to switch immediately from one source to another. So I started the same song in the CD and on iTunes and started A/B swapping.

The PC with k-mixer was shockingly bad. With the CD, the stage was big and deep. Switch to the PC and the stage collapsed and it sounded like half of the richness disappeared. It was clear, unambiguous and really bad.

I monkeyed around and tried some generic ASIO drivers but it seems that I couldn't really get any better quality out of my PC. I'm not sure that iTunes ever picked up the ASIO drivers at all, even though I had installed the Waveterminal drivers.

I got sick of PC fun and dragged an old iMac into the picture. The drivers don't appear to be ASIO for OS X - and are in beta since 2003. The A/B test with the Mac was better than the one with the PC, but it is still anemic, especially at the low frequency range.

So - here's the questions:

1) Can anyone tell me of a sound card or other solution that can bypass the k-mixer in Windows and use ASIO?

2) Once I have that - is there a way to force iTunes to use that driver? Right now, most ASIO apps have a special dialog box that you configure to use the drivers. iTunes has no such dialog box.

If you can suggest an all-Macintosh solution - that's okay too.

Thanks,

Daryll.

I'll have to give the Airport Express a try. If it sounds better, I can sell my emu-1212 to pay for it and then some. I also like the fact that it turns off the volume control so you are getting the right lineout sound level.
Daryll,

You're using Apple lossless - This is still a codec and there will be losses. To compete with the cd sound from your cdp you need to rip .wav files onto your HDD using EAC. Playback with an Audiophile 24/96 will avoid windows kmis though Maudio does introduce its proprietory Delta control mixer.
You will never get anywhere near this quality whilst using Apple Lossless!
I have been using ASIO plug-in with Foobar for a few weeks. I found it to be a bit better than without, but not hugely better. The sound stage is wide and deep with and without ASIO. It just gives a bit more dynamics to the high-frequencies and better clarity. I use upsampling to 24/96 as well because this sounds better when using a PC. MAC is better for non-upsampled data. My converter is Off-Ramp Turbo or Off-Ramp I2S. The drivers for these are quite good. The Edirol UA-5 driver is comparable when in "advanced" mode. I have no experience with Waveterminal.

If you want a copy of the ASIO plug-in for Foobar2K, send me a mail.
