I am testing the A30 right now and it does support Apt-X HD:And I'm curious, it has bluetooth 5.0 & AptX "only". Is the support for AptX HD "FW upgradeable" or is it rather HW limited?
I just got mine today. I have noticed an issue with the AUX IN when connected to a DAC. All sorts of high pitched digital noises can be heard through the speakers when I turned the volume up to 25 and higher. When paired with my old amplifier I can't hear any of these noises. When I used the A30's internal DAC via USB it doesn't make these sounds either. I'm really not sure what's going on. Has anyone else experienced these noises when using the RCA inputs?
I am using the AUX input on my A30 which is connected to a miniDSP 2x4HD that is then connected via USB to my MacMini as a source. I don't have any digital noise issues so I can't help you on this. Hope you can figure this out and correct this.I just got this in with the recent restock and I have the same issue with the analog inputs, lots of high pitched digital noise. This noise was not present when using my Emotiva A-100 and the same cables.
I contacted the seller and they sent a replacement power supply from China, but there was no change. Short of replacing the whole unit not sure what else to do. It doesn't sound like this should be the norm based on Amir's measurements.
Did you ever figure this out?

Just got one of these for my office setup. With my Grado SR60 headphones (99.8db@1mw, 32 ohm impedance) there is no problem with the headphone output level and feeds from my Mac mini through the Toslink output sound great. Now I need to upgrade the rest of my office setup.
Sorry for taking so long to make this video. Now it is posted on Youtube. A disassembly video of Loxjie A30.
I am interested in the symptom.
The noise starts to appear when the volume is raised to 25, and the noise increases as the volume is raised further, but isn't it a symptomatology that the noise decreases after passing a certain point?
EDIT: Using the same volume level as digital and turning down the input way up, we get the same results as digital input:
DA9 has serious issues as well. Many people including me returned their units due to freezing at smsl logo during boot up.Also other common problem is high DC on speaker outputs causing pop noise on L or R channel.Hello!
Have anyone compared loxjie a30 against smsl da-9 or yamaha wxa-50? I have the loxjie a30 but it would be interesting to know any comparision against them. Main source would be via bluetooth for me.
Thanks in advance!
Yeah ive heard of it. Probably the loxije a30 was the better choice here, because of that.DA9 has serious issues as well.

Nope. Sounds fine to me.anyone of you think it lacks abit in the vocal area? It seems some songs lack vocals and highs/lows taking over abit. Your thoughts on this?
Thank you for your helpfull reply! I havnt access to it. It might be the source, due to its not all songs. Streaming bluetooth from spotify is probably not optimal. Maybe ill try with cables/Another amp to see any differents.Nope. Sounds fine to me.
If you’re noticing audible midrange deficiency, I would imagine either the source component, speakers/speaker placement, room treatment etc… are the culprit, or you have a broken Loxjie A30.
Do you have access to REW and a Umik-1 to see if the measurements corroborate your impressions?
