I thought you did have a point but you did not...He is not just using a simple crystal. The module he has has other circuitry aswell including tuning controls judging by the layout. -So in the end you did not have a point because you were comparing apples to oranges.

The first of all I have found some interesting info about the av100 chip. This chip is a C-media Oxygen HD CMI8787. I found the crystal is connected to pin 46 and 47. I will put the output of JZ1 very short wire to the input of the av chip and the ground is the problem it should be near the original crystal. SO???
See, very simple procedure. I have spoke with a few people that have changed out the clocks on their cards and had great returns. You can buy these modules because you use them to upgrade CD players and improve the sound quality.
You need to decide if this modification is right for you or not.

lol ok, you're gonna do it the hard way

I still think it's a lot of trouble compared to simply buying a ST, but that sure looks most intriguing

Many people I know modify there cards as soon as they get them. Improving on the design and getting the most out of their cards.

Make sure you understand every detail of the mod before you do it. Keep the stock clock so you can always un-mod the cards if you want.
I am going to be performing some more mods on one of my cards here soon.

Hi guys!
I have upgraded the clock. Here are some pictures.
First impressions are very positive. Here are some notes:
-improvement in space (deep and wide)
-more precise projection of different sounds
-the first time I noticed that some of the instruments are more forward than others.
-the music is more relaxed - fluid
-the bass is a bomb, very precise and deep
-music is more alive
-dynamics

The installation was easy:
-unsolder the old crystal and solder the new on it. (the signal on pin 46 and the ground was found near the old crystal.)

Here are some pictures:

very nice, any chance for higher res pics please?

and what are the white caps on the burson?

what are the improvements between the LME49720NA/LM4562NA and the burson in your opinion? night and day? 50% better? what's better exactly? hope you can help

yes, the stock STX clock is really holding it back...that's for sure!

Great stuff. Looks great and probably sounds better. See told you there was nothing to the mod.
Enjoy.

MAYBE IN FUTURE)

THEY ARE FOR STABILIZING THE POWER SUPPLY.

what are the improvements between the LME49720NA/LM4562NA and the burson in your opinion?

I THINK THE BURSONS V2 ARE MORE NATURAL, DYNAMIC AND DETAILED SOUNDING.
I DID NOT NOTICE SOME DETAILS BEFORE WHIT THE LME...

night and day? 50% better? what's better exactly? hope you can help
FOR ME IT WAS NIGHT AND DAY...

YES IT LOOKS LIKE THE DIFFERENCE IS HUGE. THE GREATEST IMPROVEMENTS I EXPERIENCE WHIT ORCHESTRAL MUSIC WHIT MANY INSTRUMENTS PLAYING TOGETHER. NOW THE STX IS PLAYING SO CRYSTAL CLEAR...I JUST NEED TO LISTEN EVERY TITLE AGAIN AND AGAIN ITS AMAZING.

There is only one thing to do. The PSU.
Finally we figured out it might be the transformer, so I am waiting for a new one.
I am looking forward to that.

I am considering it. I need a precision clock anyway.
