LOXJIE A30 Desktop Stereo HiFi Audio Power Amplifier & Headphone Amplifier, Infineon's MA12070 Chip Class D Amp, ES9023 DAC Chip, USB/Optical/Coaxial/RCA/Bluetooth 5.0 Input (with Remote Control)

This is the David in the Goliath world of Dac amp combos. It’s so good! The feature set is incredible. I have it hooked up via usb to my tv and it works like a charm. The itty bitty total package for a soundbar destroyer!

I bought both a Loxjie A30 and SMSL A100 as they both featured the Infineon chip and had usb audio. There's not many amps that have both these features.The Loxjie A30 despite having the same chip and numerous more features is more efficient. It uses 1.5 watts idle and 2 watts during desktop listening. The a100 uses 2 watts idle, and 5 watts during use.The A100 has a blue light that never turns off. The loxjie can go completely dark.The A100 does have a a few pros over the Loxjie.- buit in power supply (Loxjie's external supply is surpringly large for the wattage)- easier to change inputs on the device- easier (when placed below your desk) to see/change volume on the device- When unplugging/switching usbs the Loxjie will slightly buzz the speakers. The A100 is silentBesides that the Loxjie has more advertised features that you pay for. Remote, color screen, optical in, equalizer, metal body, higher quality bluetooth, & higher quality DAC (though my ears couldn't tell the difference).The Loxjie also has a headphone jack- though from my research audiophiles say is almost useless. I tested it and it worked fine with my HD6XXs, though I didn't notice any sound improvement over plugging in my headphones into the computer, and I prefer the direct connection.I don't love the usability of the Loxjie and its wheel controls. I think it's mostly designed around the remote which for me is another thing to keep track of and uncessary for desktop use.On the A100 when using USB audio, if you software mute your computer or accidently turn your volume down to 0, it triggers the physical mute on the device. If you turn your volume back up on your computer, it doesn't un-mute. In order to get back sound you have to press the mute button on the device TWICE, and it takes a few seconds. Very annoying and finicky. The loxjie does not have this issue, it just works as you would expect.If it weren't the the mute issue I would have kept the A100 for half the price.

Wanted something I could replace my sound bar and headphone amp for my PC desk setup. Fedora Linux detected the device out of the box. Have a pair of bookshelf speakers and my hd 556s running off this

Horrible quality; I highly do NOT recommend this product. The build quality is EXTREMELY LOW, and while the audio quality may be DECENT at best, you should put your money elsewhere. I have had this amp for only 3/4 months, and as I was taking the micro USB out, it pulled the whole port out of the amp. Yup, no more micro USB ports, just a hole. Might I add, this was the FIRST TIME I EVER unplugged this amp from my PC. If you want to buy a temporary, go for it but certainly don't keep this thing around for long, if it even lets you.

Simple and purely functional for my needs.I'm using this for my TV setup, and occasional music streaming. I have some vintage speakers and sub connected to it and was able to dial the sub way down from my previous amp. I feed the audio from my Samsung TV to the A30 via an optical connection. I did adjust the delay on the TV as my Fire TV needed a bit to line up the audio with the video. Probably something to do with the optical connection as I had not run into this before.I found this little remote:https://www.amazon.com/gp/product/B08W2GY92D/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1to use with my Fire TV and turn the power on and off for my TV, and adjust the volume on the A30. This makes the setup pretty much ideal for me. Yes, I leave the A30 on at all times, it draws almost no power.Sound quality is great, my old Klipsch speakers and sub really sing with this amp and I have PLENTY of volume!! The speakers I am using are VERY efficient and this amp loves them.Update - 3-17-2023 : Still use this little guy pretty much every day. Has not given me any troubles at all. It outlasted my subwoofer that I'm now hunting for a replacement. Thought I'd look around and see if there was any neat new units that I might replace this unit with. But in a quick search I'm happy to see this is a still a very solid choice for this application. There are some interesting options out there, but sadly many lack a remote control.Funny thing is when I first got this unit it I simply sat it out on the top of the TV cabinet. I had plans to place it inside the cabinet, but I actually like the little guys looks so I keep him right there on the top of the cabinet. It never gets hot, I never turn it off, and never have run out of volume. It still blows me away that I can have such a little amp for all of my needs. One of these days I'll grab another for the garage.

Works great, sounds good, sips electricity compared to my old amplifier. I use it on my desktop PC for stereo speakers.A HUGE gripe though, is it emits massive ammounts of RF interference accross ALL HF frequencies. It's so strong I don't even need an antenna connected to my SDR radio and it looks like broadcast AM stations evenly spread occross the HF frequencies.I'm probably going to keep using it and will try to reduce the interference with ferrite chokes. But, its still not a good thing that it's emitting this much RF signal. If you have any sort of a privacy/opsec concern, you could likely pick up and listen to exactly what you're listening on your speakers if you're using this amplifier.

Powers Klipsh 600m.Purchased August 2022 for $170Plenty of power for Klipsch 600m.Plug and playDecent knob.Remote doesn't last long. (Lasted a year)1/4" headphone Out (Terrible sound quality, but it's there).Bluetooth receiver (It works. can't tell much about quality, barely used it)Overall solid buy. There might be better deal out there since it's 2025 now.
