Herman's system

[warpeon]

In a basic system ethernet will sound better than a standard USB connetion.
In my system the USB connection is by far superior over the ethernet connection.
My audio PC is highly modded and so is it's USB connection.
The Paul Pang USB card is a modded USB 3 card that, in my basic understanding, among other things, reclocks the data to reduce jitter. In my system the USB card has a separate linear PSU (Teddy Pardo, 5V ) that is conncted to the USB card with an audio grade molex cable that improves things again.

USB cannot introduce jitter as the transmission is synchroniosly clocked by the receiver.

However Air via TCPIP uses UDP for the streaming, which doesn't include any proper handshaking, but air seems to use error correction on the application layer.

Thanks for your reply Mka,

I'm no technician, hence the referral to "my basic understanding".
The simple fact is that the modded USB card sounds way better than the standard USB connection or the ethernet connection of the MB in my system.

Thanks for your insights. unfortunately having a computer next to the devialet has been deemed unfashionable by wife. Will live with ethernet connection for the time being. I wonder if devialet will ever make an audio grade 5v and 12 v switching psu to replace all the linear psu out there.
