Hello,

I have the Toshiba SD-3960 which boasts 24 bit / 196 KHz audio capabilities. I have been using the digital out to a Art DIO DAC.

I like the sounds, even with an (as yet) unmodded Art DAC. However, I would like to experiment with 24 bit / 96 KhZ recordings, by importing regular CD's into iTunes as regular (16/44) aiff's using error correction, then converting them to 24/96 aiff's using QuickTime 7.

Obviously, this dramatically increases the size of the audio files such that a 16/44 CD will not fit onto CD-R.

Is there a way of putting such 24/96 audio files onto a DVD-RW that would be readable by the Toshiba SD-3960?

Thank-you,
Charlie

One of the things about the DI/O that you should know is that it is sensitive to just about EVERYTHING. That's what makes it a great mod, since every change you make affects the sound. You can tweak it until you're satisfied, or reverse something to negate an effect that you don't like.

This applies to digital cables as well. However, this also means that the transport feeding it plays a major role. The Toshiba may or may not be a suitable transport to get the best out of the DI/O in your system (it definitely wasn't in mine).

Just thought I'd pass that along.
Enjoy,
Bob

Bob,

Thanks for the reply.  Yes, I am sure that the Toshiba is not the best option, although at present it is the best that I have, unless I can find a decently priced DIY cd-transport.

Regards,
Charlie

I'm wonder how much of an audible difference that would make by converting redbook cd to 24/96.  I've got a decent audio sound card, EMU 0404 modded, and I had a real hard time telling the diffeence between 44.1, 96, and 192.  I would simply use a real-time upconverter through Foobar and test a track at each sample rate.  

And if you use itunes to rip the cd to wav, you could actually lose audio quality, as itunes does not rip songs perfectly.  I would recommend using Exact Audio Copy or CDEX, these both provide near perfect cd rips.

If you use EAC, and then convert to 96, you may hear a difference, you may not.  My guess would be that if it does sound better that the DAC operates under better specifications for that sampling rate than 44.1.  

By all means, try it out, and comment back on your results.  I'm sure people will be interested to hear if there is a noticable difference. Hope this info helps.

EDIT:  Oh, looked up the specs for the toshiba.  It looks like the Toshiba SD-3960 does NOT support Apple AIFF, which means you will need to have a program that converts 44.1/16 pcm ---> 96/24 pcm.  From there since the toshiba supports mp3 or wma file navigation, you could probably just burn the raw pcm 96/24 song onto a dvd as a regular data disc.    If that doesn't work than you could probably author a dvd-video disc or something along those lines.

You can try this:

It doesn't use the Apple software you mention but it does convert wav files to 24/96 (along with some sort of remaster algorithm).  It creates a dvd image that you can burn onto a dvd.  It tricks the DVD into thinking its playing video but it also outputs LPCM in 24/96 on the digital out.  I verified this with my Panny XR45 and a Pioneer 563a.  The remaster does make some subtle sonic changes which are supposedly better.  I heard differences but I don't know whether they were better or just different.  You get to try the software for a period of time in limited functionality.

Enjoy.
