The board layout is noticably different and, most importantly, the main capacitors are rated for 25V and the provided power supply is 19V 5A.
You can't use a beefier power supply with this one.
Even though it is cheaper, I'll return the Douk and get a Fosi.

I guess the weather has been a factor as I still haven't received the Nobsound from Amazon. I see that the Aiyama is available at Ali Express for about $54 (including shipping) with the 32 volt PS.
I got my Nobsound yesterday and the only differences among the 3 that I can see are the gain switches which are very accessible at the bottom of the unit and (from the manual) low pass ranges from 40-300 Hz. Also, the bass frequency and volume control knobs are click-type making it easier to regain your setting if accidentally changed. I'm using the unit to replace the subwoofer amp (which failed) in my Def Tech STS loudspeaker. I re-wired the STS making it a fully passive speaker and am using REW to finesse the Nobsound settings.
Following your advice, I bought the Aiyima which was significantly cheaper on AE with the 36V PSU than the Nobsound one (~50 vs 75€). Actually, I may just use the board in my velodyne CHTR sub, since the high-pass line output still seems to work (the power amp of the board is dead). My only problem will be to find a way to put the Aiyima board on the heatsink of the sub.
