Sorry to barge in here but the AD797 chips your speaking of Purple Angel would be what model exactly and are they the ic dip-8 double type chip, and do you think they would work well with Denons d-5000 or any other chip for that matter like the LME 49860 NA you are using. Thanks.

After further testing, even enabling Front Panel audio adds interference to the Rear Panel out.

The 2nd letter at the end of the AD797XXX tells what mount the op-amps are.
N is for DIP-8, which is the socket used on the STX.
R is for SOIC, which can be soldered straight on to a PCB board or mounted on a SOIC to DIP-8 mount/adapter.
 
I picked the LME49860NA because it was only $15 for all three.
Also the LME49860NAs are the exactly the same chips as the LME49720NAs, which is the same as the LM4652.
The LME49860NA is the cherry pick (better voltage range) of the LME49720NAs
And lots of people use the LME49720NAs on the two I/V slots of the STX, so I thought it was a safe upgrade.
Would the AD797 be the best op-amp for the Denon D-5000, can't really say?
I would "guess" the AD797s would work great with the D-5000s.
 
I might try the AD797s myself,
and maybe the LME49990s also.

Sorry to bumping this thread, but what is the conclusion? not to use at all the front panel? : /
 
Its so hard to have the cable to the back of my case...knowing sometimes i can brake it because the placement of the jack it is placed in opposite direction of the direction th cable it self, its nailed (something like this >
 
It could easly be broken...especially because my case is close to the wall, and sometime i push it back in order to clean the fron part of it, so if i forogot i will totally destroy the jack/sound card input, same goes with standing from the chair with headphones on,please any help will be welcomed, nothing of this can happen if your using the front panel.

I think it may vary. I hear no difference between the front and the rear.

Don't you have other cables plugged into the back as well (monitor, mouse/keyboard, etc...)? Anyway, I believe it depends on your case. I notice no difference between the front and back on my case, but I know others who did notice a difference. You'll have to try it out for yourself to see how it is in your situation.

Thanks for the input guys, i guess ill have to roll out the whole lenght of the Headphone cable in order to avoid possible pressure/break on the jack/sound card.

Just remembered this thread existed. Anyway, on my system I did notice a difference between front and rear ports. Rear sounds significantly better. One easy way to test it was the song Superman by Five for Fighting. The first 2 seconds of the song I can hear "one, two, three, four" when I was hooked into the rear port easily at 50% volume. On the front port, even on max volume, I could not hear this. I've also noticed bass response is not as great from the front port.
 
Tested using Essence STX for sound card and my DT770 pro 80ohm edition.

I'm sure replacing the op-amps voids the warranty.
I bought my STX used.
 
 
 

asus advertises the opamp rolling as a feature. you dont need to do any soldering, just pull out the opamp from the socket and put the new one in. I dont think this should void the warranty, but just check in any case.
