Welcome to the forum Those are fine mods, even you change the tiny and almost-impossible-to-change SSIC opamp! But the adapter for discrete with MCap is a bit too long.

Where did you get those components, especially that discrete opamp DX2010?

Yup, abit long, but is intended, cos don't want to affect the resale value

The DX2010 are from DEXA Technologies, brought it from parts connex.

Planning to mod the clock by using audio-gd's Low Jitter Clock, but still figuring how to do that. Any ideas?

Just done some Op-Amp mods on the Onkyo SE-200PCI, using LME49720


Heres the materials

Before:




After:






There are a lots of improvement there...sounds really nice now

^Nice mods, since now its socketed, its roll time baby

Some of my recommendation are LT1364, LT1361, and AD8599 (but AD8599 only available in SOIC so you need another adapter)

I had LT1361 on my hand but didn't tested on the sound card yet but on pc speaker i had. LME49720 i found myself it sounds better to me compare to LT1361. LT1361 sound too harsh and lack of details and dynamic when i compare both of it without burning in yet.

Haven't tried LT1364 and AD8599, the adaptor i can't find it in farnell, what will be the SOIC adapter called?

It depends on application and the location, some might work great, some might not. You could mix the LT1361 and LME49720 on the card.

The adapter is called SOIC to DIP adapter. I don't know if they sell it or not here. Looks something like this:

Maybe LME49720 work great on my setups, if hand itchy will try find another one to swap it out

Thanks for the info, been searching around farnell, seems i can't find it there.
Mind to tell us where did you find that adapter?

You could try here

Thanks for the info....

I think i need to find myself a credit card or paypal now

Added on September 15, 2010, 2:39 amTry test again replace the sound card last 2 op-amp to LT1361, the overall details really blurred out, like cannot express the music, hardly listen to the details of every instruments, only the main played out, is that called the octave? Something like echoes of the sound when you pull the string of the guitar.

I only got that 2 models to test out so far, and LME49720 i had the best for in hand now.

Anyone tried AD797?

bro, how did you remove all the capacitors so neatly..not even scratching the PCB?

any tips or suggestion?

I have read about this fine OpAmp AD797BRZ, available locally at RS Online for less than RM80 each. It has received high regards from the Distortional Test report. (Operational Amplifier Distortion by Samuel Groner).

Perhaps it is a good Amp to mod to ?
