The other way to interact with the A30 is using the remote control that’s also provided. Controls using the remote control are intuitive and allow for full control over all the options that are available with the A30. While it maintains control over most headphones and speakers even when it’s run using Bluetooth, there is a surprising amount of bass bloom when it’s connected to Bluetooth. Although this doesn’t make the bass bleed into the midrange, it makes it a bit overpowering for already warmer speakers or headphones. The sound impressions done with the A30 were completed using the analog inputs and output combined with the D30 DAC using either speakers or headphones. All impressions are with the A30 set in direct EQ mode. Summary As a speaker amplifier, the A30 plays substantially loud, with the 2 speakers that I tested, the A30 easily drove them to ear-splitting levels. Connected to my Wharfedale Diamond 9.4, the D30 only needed to be cranked up to 25 to reach my comfortable listening levels. With my Monitor Audio Monitor 100 speaker, I needed around 30 to reach my comfortable listening levels.

The A30 has a subwoofer output on RCA connector. It is thus possible to use the amplifier to power a 2.1 system and enjoy a rich reproduction with deep bass. Bluetooth After successfully implementing the tube-hybrid mini amplifiers Aiyima T9 and T9 Pro (and an unsuccessful test with the Nobsound B100), I was curious to give a tube-less mini amplifier a try, and my choice is the Loxjie A30, which qualifies as an all-in-one budget solution with enough inputs (5x) for my setup and a headphone amplifier on top (which I don't really need). It's a 2.1 integrated amp that you can connect to an active subwoofer, like the other two. To suit your listening style and your audio system, the A30 offers no less than 7 preset equalizers as well as a customizable equalizer. The bass and treble levels can be adjusted in 1dB steps from -10dB to +10dB. Complete connection system The A30 is powered by an Infineon "Merus" MA 1270 chip (unlike the Texas Instruments chip used in the Aiyimas) which can deliver up to 80 watts per channel into 4 ohm speakers, or it could if the power supply were as strong as advertised. My setup includes a pair of efficient Klipsch Reference RB-75 large bookshelves (97db sensitivity or thereabouts). The A30 is advertised mainly as a desktop amplifier, but I'm using it in my 20 sqm bedroom as a hifi amp. The volume ranges from 0 to 60, and at 25 the A30 already delivers a sound level that more than fills the room ("Zimmerlautstärke") from my TV via Toslink. I expect I have to dial it up quite a bit for my DVDs/BDs.Built as an integrated amplifier, the A30 has speaker outputs at the rear. Despite having 5-way binding posts, the more crowded arrangement of the speaker terminals will make using bare wires very difficult. So I suggest having at least spades or banana plugs to make termination less cumbersome. I'm building up a budget HiFi setup and I've spent a fair bit of effort trying to find the best budget integrated amps on the market right now. I was a complete noob one week ago and while this subreddit has been amazing, I'm still a bit lost in all the info. As far as I can tell, the main budget Chinese amps with competitive audiophile sound quality (for the price) are: Loxjie A30, Topping MX3, SMSL AD18, and SMSL SA300. The disparity in power numbers between the 2 amplifiers may make any meaningful comparison unfair. However, when powering most of my headphones, both amplifiers can easily drive most of my headphones, including planar magnetic headphones like the Hifiman Ananda. Sound (headphone-out)​Talking about the tonality, everything mentioned in the previous section still stands. It’s a lush-sounding device with a warmer bassline and lively treble. The notes about wide and modestly deep soundstage are also true with headphones. The only difference worth mentioning is that the integrated headphone amplifier can’t fully repeat the dynamic presentation of the DAC section. Now, don’t get me wrong here, the head-amp in D30 is no slouch and it is driving my Hifiman HE4XX without any troubles. It’s just that a high-powered external amplification such as Topping L30 will produce even more slam and bass authority with power-hungry headphones. This is to be fully expected off-course and it’s not something that should bother you in any way. The in-built headphone amp is very good and more than suitable for most headphones out there.

the da-9 on the other hand sounds pretty analytical with more "air" or "definition" as if it has more reverb. I only play (well mastered?) electronic music, so this is not a huge issue... But listening to old songs, for example Linkin Park, showed that these (class d?) amps are too analytic for "last gen" recordings.

Long winded, but the point is that the answer is all of the above of what you've stated and others have stated is important. Measuring 15.1 x 17.0 x 3.8 centimeters, the D30 is compact. It features a similar build to SMSL’s M400, only smaller. The D30 has an all-aluminum chassis and it feels quite durable in hand. Thanks to its compact body and the fact that it is an AIO solution, it doesn’t take a lot of space on your desk. The has a smooth to touch grey finish and it resists scratches up to a degree. The unit comes with a good resolution IPS screen and a multifunctional volume wheel that also acts as a navigation button. Although the A30 is a fully capable integrated amplifier, the most striking feature of the A30 is the amplifier section for both speakers and headphones. With speakers, the A30 may be a bit warmer than most class-D amplifiers, but creates a truly engaging experience with more neutral speakers. The medium-grey matte finish is flawless, and the manufacturing quality excellent considering the modest asking price. Overall, there are some smart choices, and some compromises to ensure that there is enough space in the rear to accommodate the available inputs and outputs on the A30.

Layering within the soundstage isn’t the A30’s strong suit, so some images will not go deep into the soundstage. While there is some layering within the soundstage, the images don’t venture too deep into the soundstage creating a more compressed imaging presentation. DAC Input Your speakers are the voice or instrument, an amplifier is a relatively dumb device in that it only has one task which is to Amplify the input signal. Speakers are obviously going to make a huge difference because they are what is actually making the sound. Loxjie D30 is a budget-oriented, all-in-one device that can decode PCM up to 32bit-768kHz and DSD up to DSD512, natively, via USB. The highlights of the audio stage include ESS Technology’s ES9068AS premium-tier DAC, Texas Instruments’ OPA1612, and two low-phase crystal oscillators. I am including a list of specs and features below. I guess you could say that this old (class ab i guess?) amp sounds "warm", but seriously... it's just muddy (!) compared to the DA-9... The textures of the instruments are generally accurate, however, the timbre of percussion instruments tends to have a more dispersed quality.Convenient, the Loxjie A30 allows you to receive your audio files remotely, in Bluetooth, directly from your smartphone. The Bluetooth 5.0 standard combined with the aptX protocol allows for a stable and high quality transmission. EQ Mode Like most DACs, the D30 strives to be generally neutral, and to some extent, the D30 achieves that except for a slight dip in the upper midrange and lower treble. This leads to the D30 having a more relaxed presentation, ensuring that even the more treble sensitive out there won’t have any sibilance issues due to the D30. Timbre Both amplifiers also have internal DAC chips, but the one on the DA-9 is strictly used for Bluetooth, as there are no other input options for the DAC. Furthermore, the DA-9 also doesn’t have a headphone output section, so the DA-9 is strictly a balanced integrated amplifier with Bluetooth functionality. Design Listening to the headphone amplifier section on the D30, it takes on a similar tonal balance as the single-ended RCA output section. This means that the headphone output section has a similarly energetic tonal balance injecting more engagement in the music despite being limited to just 110mW into 32Ω. Although both amplifiers have a slightly V-shaped presentation, the softer quality of the L30 ends up making the vocalists less distinct. Although the nuance in the vocals can still be heard with both amplifiers, the L30 smooths over the leading edges of notes making them more blunted comparatively.

the loxjie arrived a few days ago and i had the chance to intensively compare those two, here are my impressions: The performance of desktop power amplifiers has been disappointing. Often the power is very low and distortion and noise quite high. Until now, I have not had any that I would recommend strongly. Well all that changed with the Loxjie A30. This is an attractive, solid performance with excellent measured and subjective sound quality. Inclusion of a USB DAC and Coax/Toslink input eliminates the need for a DAC for less clutter. It can easily replace a sound bar (using Toslink input from TV) and make for a great secondary system. 40 watts into 4 ohm with very low distortion and noise is plenty good for desktop use. Unlike most DACs we have reviewed thus far, the MQA decoding capabilities on the D30 are not just limited to USB. It can also extend to both the coaxial and optical connections which means that the D30 can even decode MQA-CD formats. If you stream TIDAL, the Loxjie D30 is one of a few Full MQA decoders. That means you can play MQA CDs or MQA files via digital SPDIF or coaxial input without the need of any software like Roon or Tidal. Very poor. If you need to hear sound you can use it otherwise, you should get a proper high performance headphone amplifier.

Speakers can only play what the amplifier feeds it, so if they are of sufficient quality, and not so old that they have started to literally start to fail (crossover parts on the majority of consumer speakers have a built-in countdown timer as a consequence of costs saving, they use electrolytic capacitors instead of film capacitors which last longer and have a higher tolerance of variation than any electrolytic capacitor). Despite having a larger footprint while having fewer input options, the DA-9 still ends having an equally crowded speaker terminal section. With the DA-9, there is a notably flatter tonal balance, making music sound a bit colder and overall less energetic. This can make the DA-9 pair well with some of the warmer speakers like the Wharfedale Diamond 9.4. From what I hear, the SA300 is basically a A30 without an optical input. Does anyone know if it has the same issue with noise when not playing? My Q5 Pro was basically silent when not playing so I got in the habit of leaving it on all the time. The A30 has so much noise I have to power it down when music isn't playing. The IR remote included is nicely laid-out and feels decent. I don't think the "Level"-buttons on the bottom right have any function at all though. The range of the IR is vedry good indeed, and its frequency doesn't overlap with my other devices, including my Samsung TV.
