oh yeah because dsd (for sacd) is such an open format....

this limits you to using a sacd player and a VERY small number of diy hacked interfaces. it is very possible to have good usb sound via diy. the acko aku-24 is one quality interface and twisted paer along with exa devices and a couple of others are making good inroads. imo dsd is a limiting factor and there really is very little music that is available this way as opposed for hirez flac. if you are going this way, computer as source, dsd is not an option

True, although decimation should read sampling.

False. Samples are taken frequently enough that all components of the source which are audible can be (and are) reconstructed. This is a mathematical truth.

If he understood Fourier etc. he might realise that provided he is within the Nyquist limit there is no information between samples to lose! But of course, we have been told that Fourier has nothing to do with this.

I warned the OP not to believe everything people say.

Unfortunately or fortunately because labels do care about quality recordings on SACD media since they are sure that would not be distributed via Internet worldwide tomorrow is not an open format. That is why computer DSD playback - SONY supports DSD playback on their VAIO notebooks for example - is not so practical since quality recordings above RedBook resolution is limited to SACD or DVDA media. DVDA are less popular among labels at ratio 2 to 1 in favor of SACD I would say but DVDA can be played on a regular PC tha is a bonus. I have Audigy 2 ZS so I tried - it works. Not sure if Meridian MLP decoded by Creative DVDA player or handled by sound card hardware. Most likely software playback. Anyway I prefer SACD or RedBook.

imho tweaking something like OPPO 93 with direct DSD playback would results in almost perfect playback device. Just an idea.

Agreed with both statements 100%. I was trying to explain it in a way that emphasis the concept because sometimes professional vocabulary might made simple things harder to understand for a person who has no professional background in the area especially.

Also hardware that reveals all sonic potential of RedBookCD cost too much usually. SACD claimed to be more user friendly price-wise in advertisement articles at least.

Probably not. What's a 'regular Mac desktop'?



Exactly what digital audio outputs does your computer have?[/QUOTE]

It's a one year old Mac desktop fully loaded with every option Mac offered one year ago. Other than that, I can't tell you much about it. It's my wife's rig.

It has two built in speakers and about six USB ports on the back....as far as I know that's it.

If you want to use your mac as a server, it will do just fine. The mini jack is a combination jack, so has both analog and an optical output. It works just fine, and at this point is the least of your concerns. You will need to connect a fiber optic cable to this jack with the appropriate connector, and the result you get is an optical SPDIF signal. You will need to either have a DAC with a toslink (optical) receiver, or standard coax. If coax, you will need to convert the optical to SPDIF. There are cheap and not so cheap converters available to do this.

So, could I wire this into my existing DAC to make it accept Toslink?
TOSLINK Optical Input Module
It says ot is a Toslink to SPDIF converter with a 2-lead SPDIF output...I would imagine I could splice these leads into the the back of my existing SPDIF RCA plug.....?
