Music from hard drive better than CD?

How about "the ultimate one box system".

1. CD/DVD/SACD transport.
2. Hard disc to store the music, with playback immediately (no jitter), or later.
3. Video screen for index of library, and control.
4. Digital Power amp.
and maybe AM/FM/XM radio tuner.

Add speakers of your choice.
Look for Bose to do it.

Thanks Rsbeck. RAM Electronicssells all kinds of convertors to go either direction. If you are just buying a single-purpose digital convertor they're pretty inexpensive should you want to try your EMM labs. Multi-use converters like M-Audio's CO2 and CO3 are more expensive but can convert to almost any cable. Check them out.

I have not tried the Hard Drive with SPDiF into the Emm Labs Dac. I'm not sure the Emm Labs DAC will take an SPDiF input. I use the Emm Labs in a different room from the Hard Drive/Apogee.

Using WAV, you'd need about 80 gigs for 200 CD's. I've been told that some of these lossless codecs take about half as much space. If that's true, then you'd need 40 Gigs for 200 CD's.

I'm about to delve into this stuff as well so am very interested in this thread. From what I understand you can run your lossless digital file (WAV or AIFF) from your hard drive via a USB to SPDIF convertor into virtually any DAC with an S/PDIF input. Assuming it was recorded as a lossless file at the appropriate sample rate (or greater), it would seem to me that the quality of the output signal will then be solely dependent upon the DAC and not at all on the hard drive. Am I incorrect in assuming this? By the way, You could further convert the signal from S/PDIF to Toslink with yet another simple converter if your DAC only has a Toslink input. All these converters are available through RAM Electronics, or some other favorite electronics retailer or etailer. I would like to put the most listened-to part of my CD collection on an external drive that I can bring from home to work. Anyone figure out how big a drive you'd need to hold, say, 200 CD's as WAV files? Are those files indeed "lossless"?

Rsbeck,
have you evaluated the G4 with a spdif output into the EMM?

i am curious to know if better results can be obtained using a PC HD based transport as a source for a good audio DAC like my Wadia.

AudioEng,
curious to know which transports you aare comparing the PC to (not everyone's idea of high end is the same). would a HD and USB to SPDIF converter outperform or compete with something like a dCS Verdi?

Good thread. This is also what I wanted to achieve. Thanks.

Off topic, sorry

I have been playing around with these FLAC and SHN lossless music downloads for a while...some are better than most cd's.

In the last week I have downloaded 4 complete live shows of top quality music.

FLAC and SHN files can be converted to WAV...very nice!

I have a MAC G4 that I've used for audio. There are several issues. If you have a high end system and you compress your music, you will notice and it will not sound good. If you take your signal from the computer's headphone jack, it will not sound good. Worse, when you increase volume, you'll hear a hum that is coming from the computer. However, if you use the computer as TRANSPORT and take the signal out of the computer through the USB or Firewire port, bypassing the computer's internal DAC, and play it through a high quality outboard DAC, you can get sound that will compete with CD players costing thousands of dollars AND you will get the convenience of having hundreds of CD's available at the click of a mouse. At first, I tried USB soundcards that cost a few hundred dollars, but it only offered a slight increase in quality over the headphone jack. But, when I invested $1,000 in an Apogee USB Mini-Dac, it was a home run. Amazing sound. Natural, musical, detailed, deep, wide soundstage -- everything. Will it compete with the BEST digital players? That will be a matter of opinion, but in my opinion, players like Wadia offer impressive sound and may give you a tiny bit more detail, but to my ears, the sound is a little digital for my taste. I don't want this to turn into a flame war and I am not trying to diss anyone's gear. But, to my ears, the hard drive plus Apogee sounds more natural and involving. I admire it a little less, but enjoy it more -- if you know what I mean.

Finally, to my ears, based on my taste, my Emm Labs gear is the best digital gear. My computer plus Apogee isn't in that league -- and the Emm Labs also offers SACD playback -- but, what the Apogee has in common with Emm Labs is a natural sound. The Apogee USB Mini-DAC costs $1,000 and the Emm Labs DAC costs $10,000, so I don't want to oversell the Apogee Mini-Dac -- it isn't in the same league with the Emm Labs. But, after listening to Emm Labs, I have become spoiled and find it hard to listen to other gear. But, I enjoy the Apogee Mini-Dac. If you have the budget for Emm Labs gear, IMO, nothing is going to touch it. That's my opinion, based on my taste. But, if you are looking for a system that can compete with players costing 3,000 to 5,000 while offering convenience, put this on your list of things to consider.

The Cosecant tubed USB DAC is also intriguing. Given my eye and ear opening experience with the Hard Drive plus Apogee, I am prepared to believe that it is possible to get amazing sound from a computer Hard Drive given the proper outbord DAC.

I have not heard the Cosecant, so I cannot offer any opinion on its sound versus Apogee.

Using a USB to S/PDIF coaxial converter or an AirPort Express with coaxial out will definitely outperform any transport on the market, including modded ones. I have compared these. Also, using Foobar2K to upsample to 24/96 is even better. This is the best digital audio I have ever heard. If you go this route, you can pair either of these with your favorite DAC, SS or tube.

I tried to plug my PC (with the NVidia media built in to my laptop) on my BAT30SE pre with B&W N802's using a Cary 306 player). It's still a long way shot. It's not as musical as when playin a CD.
PC HD's store music in wavefiles(MP3)- a shortcut/condensed version of the CD. It would not pick up the whole package from a musical medium during the transfer although when replayed, the ears can still hear a complete version. Using a decent player is still the way to go for now or better yet an SACD.
I'm not sure if there's any tweaky part of it to match the CD version. Gentlemen? Ladies?

Thx Metralla.

Gordon Rankin's Cosecant USB Computer DAC with a small iMac laptop appeals more to me. We will see what Gordon has up his sleeve this year, but the sound he was getting through this system (combined with his very nice amps) at CES2004 was enthralling. Perhaps you can pick up some useful information from http://www.wavelengthaudio.com/Cosecant.html
