Funfact: On the box of the SMSL AS300 it says "High resolution USB DAC". No word about it being an amplifier in the first place. I find that to be quite funny since the DAC of the AS300 is by far the cheapest/most incapable piece of hardware on it and is literally screaming to be replaced by another device. That's like a wolf advertising himself as a chicken.

SMSL SA300 / Infineon Class D

There are other strange things.
SMSL displays the Hi-Res AUDIO logo, but the product is not listed in the Hi-Res Association registration list. Other manufacturers such as Topping are listed in the registration list including new products, but the SMSL Group has no products listed after December 2017. It's strange.

I bought Loxjie A30, and I use Logitech Harmony with it, and IR receiver is great, I can point my remote almost anywhere for examplr in ceiling and it works. So only bad is probably only remote inclued that have to be point directly to unit not built in IR receiver which is great.
I just tried switching to my 2nd remote I got with my SMSL Sanskrit 10th MKII, it's much better. I guess the quality control is very poor - no longer need to be directly in line of sight...
One possibility is that they did not renew their certification after 2017. I only see the certification dated back in 2017 on their official website:
SMSL Audio Official -English (smsl-audio.com)
Yes, I think that's right. SMSL has not submitted any applications for subsequent products. Therefore, I think that a fake Hi-Res display and a sticker are attached. On the other hand, Toppinng has registered everything including the latest products.
The SA300 does not support PCM 88.2kHz, 176,4kHz, 352,8kHz. I have previously reported this. This is a limitation from the hardware you are using.
The spec table says that it supports from PCM 44.1kHz to 384kHz, but in reality it is like this. Therefore, it can be said that it is a dubious expression.
The sound quality of the SA300's USB input is quite poor and I don't recommend using it.
Toku - thank you, exactly same happen with my Loxjie A30, same limitation via USB. But I heard via Optical/Coaxial it support that samples 88,2, 176 etc. How do you thnik, which connection will be better Optical or analog RCA ? (I have good soundcard Xonar STX II)
If connection will be analog, does it still will work EQ ?

The circuit of the amplifier part of SA300 and A30 is the same. The difference is the type of input signal.
The SA300's digital input is USB only, but the A30 also adds OPT/COAX.
All digital inputs are converted to analog and input to the JRC NJM1194 electronic volume chip. This NJM1194 is also in charge of the EQ function. So EQ works for both digital and analog inputs.
We have not confirmed that the A30's OPT/COAX input supports PCM 88.2kHz, 176,4kHz. I have 3 SA300s but not an A30. The chip used in the digital input section differs between the SA300 and A30. Therefore, PCM 88.2kHz, 176,4kHz, 352,8kHz may work on the A30. Also, the USB input, which does not have good sound quality on the SA300, may have high sound quality on the A30. These can only be confirmed with actual equipment.
I just posted some information about the A30's USB input and DAC section, here -
https://www.audiosciencereview.com/...30-amplifier-review.17547/page-29#post-892605
The A30 uses a Realtek ALC4050 USB interface chip, but with only generic Windows driver support.
The A30's DAC chip is ESS ES9023, which is OK, but nothing great.
Well possibly, but the STX II is not particularly well regarded -

By all means, get a separate DAC, but something known-good by hifi people - SMSL Sanskrit 10th edition, or Topping E30.

Hi
After almost one year of use, I'm really satisfied with my SA300, but it stopped responding to the remote.
I know the remote is not broken, because I also have an M300, so I have two remotes, both of them work with the M300, but the SA300 doesn't react, no matter what button I press (I switch from C to A of course). So I'm almost sure the problem in the IR receiver.
Someone else faced the same issue? Any suggestion?

The remote on mine stopped working really quickly. I just tried some new batteries in it and it worked. Tested the old batteries and they've plenty of power. Maybe it was taking the batteries out and putting them back in.
