@Tysun , which one are you referring is it powerdac v2 with issue?

The Powerdac v2, makes my earbuds sing. It transforms it from a baby to a grown man. :)

@cqtek , nice fr at 83% almost flat no roll off...at 84 and above the sine wave is distorted as seen its clipping symmetrically. I think that is audible did you try with headset at that level? Also, seems it will perform better with at 100 ohm and above for max power transfer.

I don't think so... We'll see after your evaluation.. :)

@cqtek, please publish your FR findings on T1. Looks promising but seems the chassis is a reused from the failed Walnut v3. Except for the internal ckt.

@CoiL what dap are you using to experiment with those opamps? Thanks

RS Components

@Themilkman46290, that's bad.. btw, where did you previously ordered you stuff's? Try Rs or mouser.

Guys, anybody measured the actual stock output impedance/resistance of the zishan dsd? thanks

Hi @Ivan TT , on item#5, you mentioned there are four capacitors around the lpf opamps... may we know the value of these capacitors and type? thanks

@Ivan TT , sounds very convincing now..the challenge of doing the mods is one of the things that influence DIY'ers like us :) :) Thanks

Guys, just asking I want to pull the trigger on zishan dsd and I have watching thread in the past days. Curious question.. what sound signature does the zishan dsd emits when compared with other good/best sounding daps? I have zishan z1 and I just plan to upgrade.. In my z1 I only did opamp...

@Spektykles , you have a genuine AD797SQ you see they have a plant in the Philippines. For that reason it's laser printed underneath. That ceramic package is for high temp environment.

Hi @cqtek , I hope you can provide FR for X3ii it would be interesting tohow see how it actually compares to QNGEE... :) :)

@oneula which one is your favorite?
