UPGRADING THE CRYSTAL (X0) ON ESSENCE STX - Page 3

I think the audio-gd JZ-1 is almost the same as the bursons one. There is maybe only the price difference))

are the big white caps given w/ the burson? the extensions as well? it's as simple as plugging them in, lying them on the card...and that's all?

so the sound is not more distorted(as the specs seem to suggest when comparing LME49720<>burson), but is actually more detailed? and how about the soundstage against the 49720NA?

last question, how long is the burson that's on the external side of the card? looks like ±6cm bigger than the card? not sure it'd fit in my ATX case...

Lee, the THD measurment does not relate directly to sound quality. You cannot look at the number and guess how a part will sound.

yes, I can imagine...especially considering that depending on the FFT size you can make the THD/THD+N figures become totally meaningless

well, if it's easy as 1-2-3 I'll dive into discrete anytime soon....all these imperfect tiny IC's are getting on my nerves

Did I mention that I use discretes or a combination of chip and discrete?

Right now I am using twin OPA-Earths and a custom built dual LME49710HA for buffer.
I change them out quite a bit for testing though.

So the ST has a cleanup chip that makes the normal jittery XO cleaner and more precise. If you used this clock in a ST it would make the timing signal very precise.
I am unsure if it is needed on the ST.

No. But its recommended.

You have to solder it on adapters or on the board.

so the sound is not more distorted(as the specs seem to suggest when comparing LME49720<>burson), but is actually more detailed?
Its more detailed.

and how about the soundstage against the 49720NA?

I dont really remember it.. sorry its long time ago.

last question, how long is the burson that's on the external side of the card?

Yes, maybe 5-6cm.)

looks like ±6cm bigger than the card? not sure it'd fit in my ATX case...

You can find other solution, to put it on the other side, or .....
Not a big problem to install the bursons.

There would be a great one if one of you guys that has all two cards, will upgrade the STX whit a new clock like mine and compare it to the ST version!!!
I would love to hear the comments)

well, I've sold my STX...and I don't have the cojones to do anything like that anyway

ok thanks for the replies, I'll see if 6 cm would fit in front of my PCI cards in the case.

so where did you get the big white caps? so you had to solder the burson on adapters? they're also not given w/ the burson? ouh, that sounds like headaches...and I like the 49720NA anyway

they say that at some point you have to add a lot more money for a very little actual gain.

I'm not sure you'd agree, but it'd appear that if the 5532/2114 is 0%, then the 4562 is 70% and the burson 100%.....70% improvement costs $10, 100% costs $150

and I'm afraid the soundstage wouldn't be as wide...

OK.

so where did you get the big white caps?

THIS ARE M-CAPS (MUNDORF MKP) 1UF YOU CAN BUY THEM OVER THE NET.

so you had to solder the burson on adapters?

YES, BUT NOW I LOST MY GUARANTY SO I WILL IN FUTURE SOLDER IT TO THE BOARD. ITS BETTER CONTACT.

they're also not given w/ the burson?

NOT, THEY SAID ITS YOUR CHOICE WHICH OF THE CAPS YOU WANT TO USE

ouh, that sounds like headaches...and I like the 49720NA anyway

NO PROBLEM

they say that at some point you have to add a lot more money for a very little actual gain.

YES ITS TRUE, BUT MY COMBO I WOULD SAY CAN BE COMPARED TO A DAC FOR 500$ OR MAYBE MORE!

I'm not sure you'd agree, but it'd appear that if the 5532/2114 is 0%, then the 4562 is 70% and the burson 100%.....70% improvement costs $10, 100% costs $150

MAYBE...

THE SOUNDSTAGE IS WONDERFUL WHIT BURSONS ITS NATURAL

the soundstage is not natural at all on the 49720NA, it's surreal

is it super huge on the burson as well?

so where did you solder these big white caps to? between 2 pins on the DIP8 adapters?

you'd rather solder the burson on the board than solder the burson on adapters? the board is more expensive than the burson....and when Asus will release the Essence Supa Dupa ST Deluxe MKII in 3 months, it'll be a PNP story

I told you I really dont remember about the soundstage whit the LMEs.

The bursons opamps are delivering natural sound signature whit deep and wide soundstage.

The big caps are soldered true pin 4 and pin 8.


I will do it the best way!

ok thanks for the clarification....I was hoping to simply the plug the burson, and that's it.

apparently the Earth OPA can be installed as is w/o any adapters or caps...well the 49720NA soundstage is not natural at all!
