Do you have Loxjie d30 DAC ? I need to know how it looks inside.

[@xqr2911]

Is the BT chip QCC3034? It's not quite legible in the video.

[@AudioElectronicsChicago]

good to see inside

[@StragaSevera-ArLeg]

Молодец 👍😀

[@andrefjoao1]

Thanks for sharing

[@chinlin1050]

A30 is a multi-functional mini dac/amplifier, which saves power, saves space, is easy to use, has good sound quality and good adjustability (EQ), and is very practical to match with bookshelf speakers.

[@dfx62]

awesome! but a detailed commentary of the components when you do the closeup would be even better !

[@Techscrews]

Good idea!

awesome video, what i was looking for a long time. thanks.

[@GILSON300LBM]

Do you think that amplifier is a good option?

[@melvinng2000]

電板設計和用料看起來很用心，就是不知道耐用或音質好用嗎？

[@Techscrews]

please eng.

[@petya-bezzvuka]

I wanted to look at the Infineon chip, but you didn't show it)

[@Techscrews]

Sorry, that is Infineon's MA12070

[@MikeleKonstantyFiedorowiczIV]

what is thar cancer, realtek processor?

[@Steve-kx4yz]

From your teardown, can you tell if the USB Realtek chip routes to the ESS Dac?

[@GeorgeWPush]

Did you ever find out of it does?

[@marceloc.morais5092]

The ess dac is only for The headphone out, It’s a DAC with a op-amp.. The ma12070p only accepts PCM in, so The dac is internal in The chip

[@sc0or]

@@marceloc.morais5092 what? 12070 accepts analog signal only. It has a I2C buss to read/write internal parameters like PMA scheme, reaction on a clipping or DC on an output, etc.

[@marceloc.morais5092]

@@sc0orloxjie uses the 12070P, not the 12070

[@sc0or]

@@marceloc.morais5092 What (to me)? Didn't know that -) Thank you for the info. That DAC doesn't make a sound worse. Infineon made everything great.

[@hanslim7]

any idea how to fix this when the IR remote stops working?

[@BronsonTheCat]

I’d like to know the same thing. Mine has just stopped working. Maybe a loose connection inside ?

[@jhayd11]

is it possible to remove/replace the volume knob?

[@Techscrews]

Yes, volume knob is replaceable very easily

[@RustProjectAntminerRepair]

What camera you use for filming?

[@Techscrews]

Samsung galaxy s20 and DJI osmo 3

[@tenettttt]

Is the case in metal/aluminum or plastic?

[@Techscrews]

Case is made from aluminium.

[@Gajendraverma115]

no tubes, only solid

[@errorsofmodernism9715]

very poor quality soldering making it easy for the soldering joints to fail under mild stresses in a few months time

[@vicentcarro]

U mean the whole pcb?

[@joenovak6393]

Yep...Very Sloppy soldering and wiring.

[@discy12345]

Make sure to be covered by warranty

[@tomkocur]

Soldering is fine, they just didn't clean flux residues left after hand soldering, that's all. BTW why would there be mild stresses inside an amp?

[@noahandky3019]

2 year of ownership, more daily use than not, no problems to report. Everything works as it should, including the remote!

[@LTUGang]

It has so little components and the price is too high.

[@Techscrews]

What would be a decent price for this amplifier?

[@LTUGang]

@@Techscrews 90USD

[@Orion-redx7]

Way too overpriced. They jacked the price up because audio science review said it had good results.

[@Techscrews]

@@Orion-redx7 What are better alternatives at this price point?

[@tomkocur]

Analog, SPDIF and BT inputs, pretty good amplifier IC, capable DAC from ESS, all housed in a metal chassis with an LCD screen. I also see Nichicon and WIMA caps used. Price seems pretty good to me. Show me a better built and better equipped dac amp at this price, or a similar one at 90USD that you mentioned.

[@stephencharlton2024]

Unfortunately not very useful or informative

[@Techscrews]

Why, what you want more ?

[@cezaro2336]

Ale gówno i za jaka kasę 😂

[@Techscrews]

Eng please

[@PossessedTricks]

please note do not buy from Hifi express

[@Techscrews]

why ?

[@user-qw6fl2vb6g]

A30 is an expensive and completely useless toy. Low power and high distortion, old DAC and low-quality bluetooth. The coaxial inlet is combined with the RCA inlet. The choice of the indicator color is, of course, touching, but this once again says that the amplifier is a toy.

[@Techscrews]

Thanks for comment, but what are better alternatives at this price point?

[@user-qw6fl2vb6g]

@@Techscrews Ali's website has many suggestions for amplifiers with DACs and bluetooth. The price is two times lower than the A30, and the basic parameters are better. Yes, not such a beautiful case, no indicator, simple packaging, but a high-quality DAC and bluetooth, less distortion and more power. A30 is a beautiful, useless toy.

[@xqr2911]

@@user-qw6fl2vb6g So basically not a single option, right? I see no link posted by you, not even single name.

Do you have any suggestions or recommendations? I'm looking for an low budget DAC preamp.
