Default Recommendations for a finished TPA3116/TPA3118 unit

Hi, I'm looking for advice on which completed (enclosure, jacks, and all) TPA3118 or TPA3116 unit would be best, preferably for under $100.

I've never used a soldering gun, and I'd rather not mess around with getting a proper enclosure, volume pot, etc., if I don't really have to. Sorry that I'm not taking the DIY route on a place called diyaudio, but I don't have the time right now (maybe some other time?)!

This would be to power a set of Micca MB42X speakers, currently being powered by an Indeed TA2021 Tripath amp. The 3116/3118 units I've found that would seem to fit the bill are as follows

SMSL SA-36 Pro
Yuan Jing TPA3116 2.1 [red board]

I also found this other Yuan Jing unit (with the blue and black board), but I really don't want to pay $115 plus $48 shipping for it.

Any ideas how these finished units compare, sound-wise, or if there are any major problems with them? I couldn't find a whole lot of info on the finished units in particular from the big 3116 thread or on Google. I'm currently leaning toward the SMSL unit because I don't need external tone controls.

Thanks everyone.

EDIT: It looks like the blue board might be able to be gotten to a usable state without soldering: just the DC, RCA, and audio jacks would be needed.
The enclosure and volume pot/knob might be a little more complicated. Hmm..

Indeed the YJ Blue/Black can be used without any soldering. If you don't require a case it works as is out of the box as it has all screw wire terminals. Just make sure you order the RCA to micro 3pin connector from YJ at the same time for additional $1.50. If you have a 19 volt SMPS brick just cut the round jack off the end and strip the wire and connect to the power in screw terminals observing polarity. I have 5 variants I the TPA3116 and have yet to case one. Works just fine but doesn't have the finished look. Of course there is no difference in sound.

They don't seem to make cased 2.0 amps so maybe the best thing is to get a 2.1 amp and not use the sub outputs. Turn sub volume down so it doesn't need a load.

Here is one for $50. Free shipping but beware Aliexpress takes a month to send stuff.

OK thanks! Searching around on the YJ red 2.1, it seems that the treble control is subtractive and I would need to have it turned up to be flat. Is the bass control similar in 2.0 mode, or is it just a subwoofer volume control for 2.1?

Alternatively, I wonder if I could easily bypass these tone controls somehow (I've never really liked tone controls to begin with)?

More searching I must do, it seems.

I found the same red 2.1 on eBay for a similar price. Would I be better off with Aliexpress or with eBay in terms of reliability of sellers, etc.?

I've pulled the trigger on a YJ 2.1 unit. Does anyone know what sort of DC connector it takes? I can't really tell from the pics on YJ's site (it seems to be 5.5mm/2.5mm), and I'd like to get a 19v psu for this.

It's the standard 5.5 mm jack that is on most laptop bricks. Aliexpress is slow but reliable. They refund no questions asked if arrives damaged or late beyond date of stated delivery. You get to keep for free if it show up after date. But slow.
