Aside from the max output of 1.7V for the plus vs 1.4V for non-plus, everything looks the same as far as the chips used on both products. I don't read Chinese but from this table it shows the Plus just have a higher output.

I ordered the MU2Plus for $130 before it got a link, I think they are charging $10 more because they are the only seller offering it right now. Once a few more pop up the price will stabilize but yes, it is in the $110+ range in China and the resellers take their cut...
prices stabilised a bit: https://www.aliexpress.com/wholesale?SearchText=musiland+mu2+plus&opensearch=true

sale price $124.24 in 5 days

0.5V 1k thd measurement No 900hz weirdness from here. Using hf player on android playing my test tone file.

THD of MU2, 0.0004% at 44.1kHz
However, I don't think the ADC of Soomal is good enough to measure DAC.
Both look great to me

Just received mine. Lord this thing goes LOUD lol, seemingly quite a bit louder than smsl idea.

I don't like that it seems so flimsy. The cable really just dangles. I can see this break. Other than that I like it!

Shame MU2 has been discontinued. I'm expecting MU2 Plus any day now as I've been very impressed with MU2 (non-plus) but at the price the plus version is selling, it's a bit of a tough sell for impulse buyers. Really nice for those who need a tiny USB-C dongle without the hassle of the need to charge battery for (another) extra device. Don't have to deal with android-based DAPs which can be quirky/slow/limited (and expensive) either.

And yeah, the cable is kind of flimsy for the price, gotta remember to get those spiral cable protector.

I wanted to get an MU2 Plus for use with an rpi running Ropieee. Unfortunately I didn't pay attention when ordering and I got the regular MU2 instead. It sounds just fine with good functionality and compatibility with my phone and the rpi. Right now I'm trying to use it with my computer at work (Windows 7 Professional) and I can't get it to work. I expect that a driver is necessary but I haven't found one so far. If anyone can point me in the right direction that would be appreciated.

I'm not using it with the rpi yet since plans have changed so right now it's going mostly unused. @amirm would you be interesed in measuring this?

Yes, would be good to characterize it since the plus version is so hard to find. You have my address if you want to mail it to me.

Have you tried both USB2.0 and 3.0 ports?

I mainly use mine with android devices that have USB-C ports, but it works right out of the box without additional drivers on my main PC that has the latest version of W10 installed, even recognized Musiland name... Don't have a W7 machine to test and I don't think Musiland offer drivers for MU series, sorry

Sure be gentle with the cable, better to get some heat shrink tubes. Mine got unstable connection just after I post my measurements and I had about 3 months at the time.
