Thank you for this. I can see connecting to the A30 via USB/Bluetooth is not ideal.This is the last time

You are better off with the digital inputs on the A30 because the weakest potential point in the system is the A30's analog input.Hi everyone
I recently got this Loxje A30 amp, running from my macbook via USB, then hooked up to a pair of KEF LF50 Metas.
I've read a few times in this thread that the A30's built in USB DAC leaves a little to be desired.
I also own a Focusrite Scarlett 2i4 v2. Would the DAC in the Focusrite be better than the one build into the Loxje A30?
I found this review of the Scarlett:
This is a review and detailed measurements of the Focusrite Scarlett 2i2 Audio Interface (DAC/ADC). I was talked into buying it recently. The 2i2 costs US $140 including free Prime shipping so very reasonable for amount of functionality. For a budge device, the Scarlett 2i2 looks pretty good...www.audiosciencereview.com
I also own an apple usb dongle:
This is a review, detailed measurements and comparison of Apple's USB-C adapter to the current and last version of Google Pixel headphone adapters. The Apple adapter costs just $9 including one day shipping for free. The Google dongle costs $12. Not that any of these are large by any stretch...www.audiosciencereview.com
Unfortunately, I don't know enough to interpret the graphs/review of the A30 vs Scarlett DACs to work out which is better. Help!?
Ahhh that's really interesting. I think I understand what you're saying here, thank you.You are better off with the digital inputs on the A30 because the weakest potential point in the system is the A30's analog input.
That said, everything is competently done on both devices, so if you want to use the other features of the 2i2, the A30's analog inputs aren't bad, they just aren't as good as its digital inputs.
You don’t need a new DAC, just a usb to optical/coaxial adapter such as Doug Audio U2 USB converterAhhh that's really interesting. I think I understand what you're saying here, thank you.
So basically, my next best bet as an upgrade to my setup is a new USB DAC, then from that use the optical input on the A30?
So much to learn here. Thanks for all the help for a newbie.
The A30 unfortunately didn't work with my C-Notes. I had the exact same issue as these folks: hooking them up normally, I get nothing but a periodic popping sound from the speakers about 1 second apart - some sort of "protection mode" I'm guessing. Placing a resistor inline with the speaker wire makes them work, but there's a constant static/hissing sound coming out of the A30.
So I've seen this issue reported with the Polk XT20s twice, the Overnight Sensations once, and the C-Notes once. Maybe the MA12070 (or Loxjie's implementation of it) doesn't like something about the crossover design with these speakers. Or, seeing as half of the reports are DIY, it could be faulty assembly of the crossover.
Now to decide if I want to try another amp with the same chip, or just give up on the MA12070 entirely and get an Aiyima A07 or something. It sucks, there are so few options with remote volume control
I believe this is wrong - the Loxjie A30 has the Merus MA12070 amplifier chip, not the MA12070P. Refer to the text and image on the official Loxjie product page -The A30 is based on Infineon MERUS™ MA12070P
That would be wrong, then.You are better off with the digital inputs on the A30 because the weakest potential point in the system is the A30's analog input.
Yes, I suspect the 2i2 would get you better sound quality than using the A30's USB input.I've read a few times in this thread that the A30's built in USB DAC leaves a little to be desired.
I also own a Focusrite Scarlett 2i4 v2. Would the DAC in the Focusrite be better than the one build into the Loxjie A30?
But have you looked at this topic carefully?The DAC discussion here for USB input versus optical is dizzying. I wonder if some people are confusing louder (via optical input) as better. A common misconception in audio.
Where in the specs or schematic does it actually specify that USB bypasses the saber DAC chip? Has Loxjie confirmed that?
I am open to buying the Douk Audio U2 converter if that will make a difference in audio quality (not volume). At $55 on Amazon and considering the very low price I paid for the A30, it would not be a hard pill to swallow. I absolutely don’t need louder — my setup is for desktop audio and my head is 3 feet from my speakers. I’m running the A30 at around 20 on the volume control. But I do want high quality audio.
I will add that it sucks the display does not show the sample rate when using USB input, but it does for optical. Why the hell...
You don’t need a new DAC, just a usb to optical/coaxial adapter
This notion of adding a USB-to-s/pdif converter to the A30 seems popular, but in my opinion this is a convoluted configuration, and not good value overall.I am open to buying the Douk Audio U2 converter
Hello, I bought the Loxjie A30 and I have a problem with it.
Before buying, I made 1.5mm2 (16awg) pure copper wires with a length of 1m (40in) to connect the columns (8ohm) with new amp. After connecting, the loudspeakers didn’t work, they made a clicking sound about every 1s. Heaving in mind that wires are hand-made, I connected to amp the first wires I could find – short wires of standart quality (img below).
Everything is still alright with the A30 and Wharfedale 11.1? Is the A30 getting hot? Do you listen loud sometimes? What's your max. volume you turn the A30 up to?Have the bedroom setup complete now.
Wiim Mini > Loxjie A30 running a pair of Wharfedale 11.1.
Fed exlusively via Tidal Connect directly from the Tidal App. That just works. Havent opened the Wiim App since setup.
Quite happy with that. The A30 has absolutely no problem driving the 11.1.
And while it obviously sounds different than my living room setup (X4700h + Triangle Borea 5.0 surround setup) i would have a hard time right now to argue that the living room setup is worth so much more when just listening to music ^^
Welcome Aboard @almosely , we are glad you have rejected the Lurking “Dark Side”.Hi everyone,
I've been reading here for years and I love the forum very much!
But now I actually have a specific question that I can't really find an answer to in the vastness of the internet.
I just ordered a Loxjie A30 for my TV and a pair of Wharfedale 11.1 speakers and an Elac Sub 3010. My TV has an optical output. I got the 11.1 for 200 EUR (pair price).
The Wharfedale 11.1 should have an impedance of 8 ohms and a minimum of 4 ohms. In fact, this was tested differently there, namely with two impedance dips that go down to 1.9 and 2 ohms.
There are various ways to bend the rule of loudspeaker physics which says that small speakers are insensitive. You can increase cabinet internal volume, lower impedance or curtail bass extension. With the Diamond 11.1, which has a high sensitivity for its size of 87dB (the specified figure and...www.hifinews.com
I don't listen at disco volume anymore, but usually very quietly. But every now and then there could be a higher room volume if I feel like listening to music.
Can the A30 drive the Wharfedale 11.1 with ease, or are the two low impedances potentially detrimental to the A30 and/or the Wharfedale 11.1?
Alternatively, I could get the Wharfedale 12.1 and send back the 11.1 untested, but they would cost EUR 340 (pair price). However, these were tested here with higher ohms.
This is a review and detailed measurements of the Wharfedale Diamond 12.1 bookshelf speaker. It was kindly purchased by a member and drop shipped to me. It costs US $399 for a pair. The look and feel of the 12.1 is definitely above the budget category: The back is rather pedestrian but...www.audiosciencereview.com
Many thanks for your information in advance!
For people who want to go the optical way and save some bucks (well who doesn't ? ) I have a cheaper way to do it : instead of converting USB -> Optical I'm using an HDMI audio extractor -> optical instead. It's cheaper, 70€ for doug converter vs 26€ for this audio extractor.
