This thing feels weird on my speakers, might be because im used to the EQ settings for my HCS2330

but connect it to my AdagioII, Consonance and M2......the sound is just.......fuh DAMN

I bought another unit for my fren, not an audiophile......but a satisfied buyer

this is what he said:

Yes.

not only due potential loss of bits, but also highest SNR when you're at your max volume.

Then again, if you don't have line out, any amp = waste.

dun use the DAC with your previous EQ setting bro let it flat , if u really want tune the EQ, tune it precisely by start from flat after connect to this DAC , adjust according to what your speaker system cannot give u or to suit your listening preference.

UD100 next to ODAC.

Surprisingly UD100 measured very well in RMAA, even against ODAC. I think it is safe to say for now, at least for my ears, UD100 is 95% of an ODAC if not more. Really excellent USB DAC for the price.

What is your rmaa setup like?

Nothing fancy: PC - (USB DAC) - O2 - Behringer UHA222 for line-in. Didn't use any load for O2 because it doesn't matter in this case. I am just looking for the difference between USB DAC. I would have forgone the O2 if UD100's volume is adjustable on Windows.

For listening, it is PC - USB DAC - O2 - RE0.

Are you sourcing them with the same PC? Because if you are, you're having ground loops -> hence problematic results.

Fortunately, ground loop isn't a problem on my PC. I tried two PC setup before and it doesn't make much difference. Also played with USB isolator before as well.

Ground loops is not PC dependent. It's when you tie an "extra" ground with the sleeve of the jack when the ground is already shared within the same PC.



To be honest, RMAA is rarely a good gauge of absolute performance. It's very finnicky. I kinda side with nwaguy in RMAA's case.

I don't disagree that RMAA isn't the greatest of tools, but it is free. If I have that kind of setup like NvAvGuy, I'll learn how to use them. But till then, RMAA is here to stay. However, the key is to know RMAA limit and know what to look for (and what not to). Even with a bad tool, it can still work if you know how to use it right. Which is why I measure the UD100 against ODAC, which has been well documented. By looking at the difference between result instead of pure number, a lot of things can still be told.

Well, if that fail, I still have my ears and a digital SPL meter to match the volume.

Tried ARTA yet?

Heard of it but never try. I thought it is a shareware, no?

naw mate.

My senior used it for his FYP.

Ok, will try it sometime.

FUH...This is fit perfectly nice

UD100 -> cMoyBB v2.03 (with OPA637BP) -> Recabled Koss KSC-75

the sound stage, detail really nice
definitely better than FiiO E7 DAC alone.

why didnt i think of this?! i also have a few card readers lying around

like tailor-made housing/casing

use FiiO E02i Rocky + UD100 good ah?
I know the mic doesn't work here

E02i is okay with UD100. But if you are just looking for minimalist setup, E6 would be better choice than E02i.
