Of course. It won't be scientific, but I can compare it against the TPA3250D2EVM, various TDA7498s and a plethora of TPA3116's.
Thanks for your patience since this is a economy shipping and it will take 7~14 days normally.
any questions and compare are also welcome to discuss here to all of the DIY guys.
It arrived on Wednesday, but I was only able to collect it from the Post Office yesterday. Fast delivery, the best packaging I've seen on a China shipped parcel. Good after sales communication on how to connect etc
Quickly connected it up to a 36v SMPS, Q Acoustics 2050i speakers, driven by an RPi, Mamboberry LS DAC & Kali, running Rune. listening to Nicolas Jaar Space Is Only Noise.
First impressions are of a very quiet amp without a source, and I had to turn my ALPS pot down compared to how I had it using the TPA3250D2EVM.
I am so far very impressed, need to do some more listening...
I look forward to reading your comments when you have it up and running. From memory, I think you already have a TPA3116 board?
So does this design use the post feedback circuit discussed in the main thread that's supposed to reduce noise even further?
not used but had combined the option same with Demo,
btw,you need to be very careful with the post filter feedback especially without loading.

I've just discovered your project. This is pretty exciting really, you've got a 36v smps designed for this thing. This new TPA3251 really looks sweet. Have you considered making a DAC board using the PCM5242? That would be pretty amazing. It's designed to work perfectly with the 3251 and if I'm not mistaken it features minidsp functionality.
I may try this board with the Behringer U-Phoria UMC404HD as a source. I've heard it sounds quit good and has XLR outputs.
It looks like it could even function as a stand alone DAC since it has digital inputs and external power. Not sure though. Apparently has SNR of 120db.
What are you guys using as a source for 3eAudio board?

I use it in SE mode, fed from my Raspberry Pi, Kali and Mamboberry LS+ DAC. The following may help:
