that was probably the so called 'burn-in' effect...

ROFL I don't believe burn in on transistor though. No the opamp is new one, I ditched the old one. I never use a used opamp unless its socketed

me as well...i just think that the sound better after 'burn-in' is just our ears more adapted to the 'new' sound over the time...

I guess so, makes me think its a waste to buy new opamp anyway. But at least I have some backup since my SOIC opamp has run out

yeah.. second tat

Very weird, when at night LME49720 sounds good, while at day it was too sparkly to my tastes

Hmm....this thread is dead again....still waiting for the opamp, but in the meantime I order yet another opamp This one is ultra secret opamp Some say....this one is perfectly balanced sound signature, some say its too veiled. All in all, they all agree it have bass, a big one

Ultra Secret...LOL'ed at Najmods...

Now my card acting weird, right channel all of the sudden go totally silent. I check for continuity but everything is fine but when I run it there is no sound at all from right channel

maybe too much 'burn-in' how about take the output directly from opamp?

No, still no sound

But I found the culprit, a small SMD resistor is loose, removed it and I directly connect to output without opamp with the wire. Surprisingly it sings well, and no sign of excessive DC offset. Very weird I hope it stays that way

Gosh, I though this card is a gonner for sure

you means now you bypass an opamp again?

Anyway congratulate to you for arrival of new sound card soon...

Yup, and this time it worked well. No sign of excessive DC offset, I measure it it exactly the same as with opamp, around 190mV

Actually without opamp how much the volume of sound decrease at same level?

Quite a lot actually, maybe up to -9 to -12dB from with opamp

Maybe you need to use another opamp place as front channel if you want to use opamp anymore...

Hmm, maybe....anyway I need to use the decoupling caps, the DC offset is too much. Found some good quality capacitor that is small enough I still waiting for my opamp to arrive so I leave the space bare first ready for new one

Can Elit Pro pair with passive speakers?

elite pro is jus a sound card, not an amp my fren

DAC can?
Elite Pro with Amp plus speaker.. very bulky.
Aego M have build in rite?

Was thingking to pair with Wharfedale Diamond 9.1

You still need an amp if you buy the Wharfedale, only the AegoM have internal amp
