Hello all, I'm new here, this is my first post
I have bought a XONAR STX for my home system, and after numerous tweaks and mods, I finally reached the sound signature that I like
If someone is interested I can post later the list of my mods
The last one was replacing the crystal clock with a Vanguard TCXO 0.3 ppm, available from a Hong Kong vendor on Ebay
I saw many post on the Net about the quality of this oscillator, and the benefit it brings on this sound card vs the stock oscillator
I have to say in my case the result is not satisfing, a step backward in the overall sound quality
The sound becomes dull, sterile, with harsh vocal sibilant, not immediately noticeable, but in the end I found the music is turned gray, uninvolving, and fatiguing after a while
I tried to supply the oscillator with a dedicated very low noise PSU instead of the onboard 7805 , but things doesn't improve
Restoring in place the stock oscillator gives definitely a better result
I can't understand the reason for this behaviour, I can't measure it, but it seems the vanguard XO exhibit an higher jitter than stock one
I noticed also the stock XOon my STX is marked IT405, and all pictures found on the NET show IT475, maybe ASUS has replaced this component with a better one in recent items?
Any idea, suggestion, please
