This is something can be done with both 11.32 and 15.32 (my friend hav also try with other brand DAC)

** For the guy who did't used optical port **
1. Open up the case and just take out (unplug) optical connector plug !! U will see the different !!!
note that!! no special tools required just ur finger is enough or if u hav a big hand screw driver can help)

Short Conclusion
The Reason why sound change is because The optical port use the same 5V current as DACs chip as we know that even we didt use them but it will work all the time to dectect if the optical cable is connect or not. ____Skip long explanation ____ It disturb DAC chip .

For me after done this the sound is a lot more clear n smooth u can notice this different immediately !!!

In the case that u want to use optical cable or did't like new sound u can just plug it back whenever u want
** If anyone want the picture of what i hav done just PM me ur email ^^ **

Credit of this method to Thai Engineer that i know ^^

Interesting stuff, I'm itching to try this out but will wait for an official word on it first.

From the foobar menu:

File/Preferences/Tools/SACD

You select:

ASIO Driver Mode: PCM

PCM Volume: +0db

PCM Samplerate: 176400 (max)

DSD2PCM Mode: Direct Double Precision

Preferable Area: None

Ok, so Audio-GD doesn't accept DSD? Only PCM?

Correct

Alright wrt to the unplugging mod, I did try it. Didn't hear any difference...initially. Then I realized after a while that the details pop out more across the frequency. Its a little more forward. I can hear the background details in some songs more clearly, with a little more body and punch (for the songs that I demoed). It isn't a huge difference. Takes a while to notice. But ya I'd agree that its there. And I like it.

I think since the optical cable unplug mod is super simple, to avoid expectation bias, just pull the unit top off and get someone to plug the optical and unplug the optical out of sight and then you'd know for sure it is a detail/performance booster.

Also people talk about unit burn-in, but I think after reading the Audio-gd site the units are already burned in prior to shipping to customers.....so it must be "post-burn-in burn-in" then o2smile.gif

We'd really like Kingwa to address the idea of change when optical out is disconnected. I'd bet dollar to donuts he tested this already.

I have read that 100 hours are burned in when you purchase a new unit but another 200 hours needed to sound its best.

Got too itchy and ended up doing the optical unplug modification as well. Call me easily swayed by confirmation bias, but there does seem to be a boost to transparency. Also sine waves sound cleaner now, that I know for sure.

post #825 of 1363

Hmm.. just tried the unplug mod on my 15.1 and it does seem to sound cleaner. Pretty hard to get the plug out from the corner though but no damage done.
