Post Subject: USB or do not USB?Posted by Romy the Cat on: 9/30/2008

Gordon Rankin, it is the guy who promotes the silver-wired transformers? Oh, yes I need to put him my news section….

On the serious note I do not know if your IT people are correct as it might be too deal question to them and average corporate IT people do not operate at this level. I think it might be worth to try to shot down all audio devise in computer bias (I do not know if MAC has it) and to try getting audio out of USB then.  I think I would make a call to Lynx asking them what is relationship between USB and soundcard and where they devises located in hierarchy. Lynx support juts phenomenal, they have the real engineers answer the phone not juts customer support ignorants.

Still, it is kind of odd. As I understand ether USB, firewire or SPDIF-AES/EDU requires own circuitry to support I/O – they are all not straight connection. Perhaps one id more complex or more intrusive – I do not know. What I do know that it might be easy to test. All the one need would be a DAC with USB and SPDIF-ASE/EDU interfaces; there are a few out there, including from Gordon Rankin as I understand:

Then it would be worth to drive the DAC from the same PS via USB or ASE and to compare the sound. If sound would be different then it might be zillion reasons way, including the specifics of a given USB or ASE implementation. However, there is a chance that it will not be much difference…

I do not have a DAC/ firewire DAC. There are how a number of devises out there who do conversion from USB to whatever:

Anyhow, I need to educate myself about all of it… who know if the USB is so low level and so simple then why not to found at any existing DAC the point where a pure I2S in presence and to hard- wire the USE pot right there?
