Curiously the photos show two different backplates, one where the RCA right channel in is shared with the coaxial input and one without coax input!
(And it's the Loxjie official store)
Besides, other than your link above I can not find the A30 from AliExpress search function, neither from Loxjie official store homepage!

Thanks @Zek. What I meant is that @sweetchaos post a link to A30 on Loxjie's official store on AliExpress that I can not find it in the ways I posted.
Plus that webpage linked showed two different (though similar) products, each one with different options: with and without coax in.

My A30 will arrive on friday
Does your A30's standby feature mean auto Sleep & auto Wake?Can you guys please try feeding it with USB? I will use Raspberry and Im a bit afraid that standby wont work while connected. Thank you
Unfortunately, the A30 doesn't have such a feature.
There is a function to automatically turn off and turn on the display.
Yea I meant that it will go to standby mode on no signal input after some time and turns back on when it receives signal. Cant believe it doesnt have it
Edit: I checked the manual and it says its consumption si <0,5W in standby and that It has a low-power standby function that meets the latest EU ErP2 standard. Not sure how it works though.

Been using my A30 for a few hours and really digging it. Much prefer it over the AD18.
What are some of the reasons that make it better than AD18?

The screen is nicer, it is much higher resolution
I like the auto screen off feature.
There are no pops when the amp is turned on
The EQ options are more usable to me, I don't know what the "tone" EQ setting is doing but it sounds a bit like a "loudness" EQ which is great to have. I didn't like any of the EQ presets on the AD18.
I THINK it sounds smoother to my ears, unfortunately I cannot directly compare to the AD18 as I no longer have it.
I prefer the remote control, feels much nicer in the hand.
I prefer the volume knob on the unit itself. My AD18 had a horrible volume knob that wasnt accurate at all, it would skip and jump between each notch. The A30 knob feels great to use.
I prefer the volume increments, the A30 goes much quieter than the AD18. Also Volume level 1 actually works!
Some negative points are:
There are some buttons on the remote that have no function. (like the AD18 too)
When you power off the amp, if using USB audio the USB device will completely disconnect, unlike the AD18 which remained as a connected device.
I noticed some oddities like for some reason the bass was set to default +10 and treble +8, although they weren't actually in effect until I nudged the settings. (So it seems the Preset EQ's are literally just that, they adjust the treble and bass, but if you set a preset EQ, and then open up the option for treble and bass, it will revert back to whatever bass or treble setting was manually set to last. For example, if I manually set my bass to -10, and then turn on the "super bass" preset, it will behind the scenes turn up the bass amount, but then if I navigate to the bass option and open it, it will show -10 AND set it to -10, rather than just show the preset value. I think the AD18 EQ presets were independent of the bass and treble settings but I could be wrong.)
Some weirdness with the windows driver detecting it as "Headphones"
I havent tested any other input source than USB so far.
Really enjoying it though, just feels more premium to me than the SMSL.

How about the standby mode? Stays asleep until signal on?

Not quite sure how I can test that. I haven't noticed it turn off by itself although it's hard to tell when the screen is off..

Maybe I am going insane or have some serious placebo going on, but right now this amp sounds so much nicer than the AD18. I am wondering if my AD18 was faulty or something because this is way fuller and rounder and just way more satisfying.
inb4 it measures terribly xD

Maybe because the ad18 was insanely underpowered?
