Will computer to DAC replace transports and cdp's?

configured as RAID 5, so its pretty safe. If I blow up two drives at once, guess I'm reripping everything, but that prospect seems pretty minimal

I think it's just a question of time before computer storage makes CD/transport systems obsolete, but I'm not sure the technology is quite there yet. I use very expensive RAID5 systems in my work and have had 4 of them fail (3 because 2 drives failed at the same time, and 1 because the RAID5 hardware failed). Streaming music is much less data intensive than my work, but consumer RAID5 systems are probably much less robust too, so I would not be surprised if some people will be dealing with RAID5 failures and re-ripping all their CDs. RAID6 might help, but when I switch to a computer system I might use a single large HD, with a second disk as a backup, just to keep it simple.

I like the idea of using a computer based system, but I also like the simplicity of the CD/transport, and if CD is very close to the quality of a computer system I'd be happy to stay with the CD/transport until computer based systems are perfected and made relatively simple, hopefully that will be soon. For people who like playing with hardware and software I think computers are the way to go now - for me that still feels too much like being at work.

Another point - Steve Nugent is developing computer audio systems that avoid the conversion from I2S to SPDIF, when that's ready it might be another good reason to go with computer based systems.

I've had really bad experiences with consumer drives, but the Buffalo seems to be holding up well. I've actually got another 1TB PowerVault 645N with RAID 5 in my garage as well... That one gives me more faith, but my god it's loud!

That said, I figure the CDs are sort of the backup-backup. Some people sell 'em... I like having them around, even if they are packed in Xerox boxes in an upstairs closet...

Hi All,
I agree that eventually this will be the way to go. There is a VERY exoensive DVD system called Kaleidascape (sp?) that does this for movies. It will also hold HD material. AS you can imagine, it takes very large drives to hold that much material. It also retails for $30,000, at least. I can foresee the not very far future when all the dat will be sent to a high qulity set of DACs, say a Theta Casablnca with room correction. But it will take sveral years to make it availabl and affordable. Also, the storage softaware and algorithms have to be standardized. Meanwhile, I am REALLY enjoying my Esoteric X01 and my Meitner gear (one of which will eventually get sold).

Don't get me wrong, I'm not dissin' you or your masterful grasp of the technology involved.

However, your post reminds me of a tech company I worked for. This company used PCs instead of mainframes (my thing). To obtain test data, I had to perform a 35 step procedure to get data from one environment to another (so I could use it). I didn't stay there long.

As for the short-term memory thing -You're absolutely right! The upside is I've had 35 years of practice coping with (artificially induced) senility!
Old age? Bring it ON baby!

I'm somewhat surprised that nobody has really mentioned the issue of jitter. Reading the data without errors is not the problem (in a PC), but the data stream going out is still controlled by the internal clock (on the sound card), which the clock in the DAC syncs up with. Here's an excerpt from a review of the Lynx 2 audio card:

"Some time ago it was assumed that high-quality sound could not be obtained at all on a computer system because of magnetic pickups from a video card and a processor into the sound card's circuit of the printed-circuit board, terrible power supply from a pulse power supply unit, jitter in converters, inadmissible usage of transfer electrolytic capacitors, low-quality connectors, cheap components of the analog section. " [http://www.digit-life.com/articles2/lynxtwo/index.html]

The best approach seems to be to have the master clock in the DAC circuitry and have it control the transport's sending clock, or have them be one and the same. The latter may be done in integrated CDPs, the former can be found in products from Wadia and dCS as well as high-end audio cards (Lynx L22, LynxTWO, Emu1280M).

Like many of you I'm in the process of capturing all my CDs (to ALAC - Apple lossless), but I'm not sure a $100 or even $200 sound card will do high quality headphones or speakers justice.

BTW, some of you were looking at controlling the music remotely, and the touchpad option is certainly a good one. Something else to consider (especially if you aren't overly concerned with jitter coming off a hard drive based source) is the Sonos music system. I own several of their zone players and controllers, and it's great for listening over my built-in speakers. It's biggest plus is ease of use (very reliable, intuitive, and a killer interface especially with the little wireless remote). The built-in DAC is ok but not the greatest, but they are coming out with a zone player with digital out, which would let you use an external DAC and amp (not sure about jitter though). Highly recommended!
