Will computer to DAC replace transports and cdp's?

Steve,

.....The fact is that computer-driven audio is intrinsically superior to reading of optical disks. The only way CD's can compete is if they are read into a FIFO buffer and then read out with a precision clock, which is essentially just equivalent to computer-driven anyway....

Again, even a 15 years old CD player has a built in FIFO buffer as well as C1 and C2 error correctors. I am not sure about your “modded CD transport”, but ALL of today's universal players also feature large RAM buffers and spin the disc at x2 to x10. The data output is free of error and jitter. So, as you see, the statement that computer audio is "intrinsically superior" is not exactly true. Not to talk about the fact that computer audio is not even remotely close to the reading accuracy of the Esoteric's VRDS-NEO transport, or even some of the older Sony and Philips top line CD transports.

There are many, many factors that come into play for best digital reproduction. The computer audio has the potential combined with great convenience. Sonically, it is very good, but still not quite there yet compared to well engineered "classic" digital boxes. Well, may be some day. :)

Alex - I agree that if the entire track is read into RAM and then played back from RAM, then it has the same flow-control and clocking advantages of a computer, but to my knowledge, none of the available CD players do this, except for maybe the Meridian, which is evidently just a CD-ROM drive and a computer anyway.

If you go to all this trouble, then why not just put the tracks on hard disk, where you have complete control over them in software, unlike the tracks on an optical disk?

Steve Nugent,
Which computers have a I2S or I2Se interface?

My recent experiments with the computer and a USB DAC have proved to me the superiority of the computer model for playback of CDs. There is no going back for me.

Mburnstein - You dont want the computer to have the I2S interface. This would introduce computer clock, power supply and ground noise into the signals. The best way is to use an external WiFi or USB to I2S converter with it's own power supply, preferably battery. My company makes these. The result in unlike any digital audio you have heard. Eliminating the S/PDIF interface makes a huge improvement by reducing jitter to infinitesimal levels. Here is a link to a recent professional review of an I2S-based system:
