Review: Small but powerful in an elegant package - This is my review of AIYIMA A07 Max as comparing with AIYIMA A07 Pro and A08 Pro. I have had this unit for almost a month and I have been using it to test and listen to various audio tracks. My overall experience is that it offers very much the same sound quality, expansive sound stage, dynamic tones, and clear instruments; pretty much what the other latest AIYIMA amps offer based on the same TPA3255 and NE5532 amps. However, what sets this apart from others is probably its use case which is that it offers a mono-mode meaning, you can drive the left and right channel audio into two individual A07 Max and have the ability to push more power into the speakers (given you use the right power supply). Another distinction is that AIYIMA A07 Max does not have any Bluetooth support unlike the A07 Pro or the A08 Pro which maybe what might be preferred in certain cases. It not only simplifies the circuit and internal components but also keeps the cost down. Speaking of internal circuits, we can see from the images that AIYIMA has improved on the internal capacitors used. The two main capacitors have now be upgrades to Nichicon 63v as opposed to 50v used in a previous version. This gives it plenty of headroom to provide enough power during certain spikes in load. The TPA3255 chip is cooled with a massive heatsink that makes contact with the aluminum unibody, allowing it to dissipate the heat relatively quickly. There are plenty of vents on the sides and the bottom to circulate enough air to keep the amp at normal operating temperatures. The binding posts in the back are now much sturdier and feel premium compared to the other two amps. The posts are also staggered so there is more than plenty of room to plug in the speaker cables. I want to also quickly highlight the volume knob which also serves as the power switch similar to the A08 Pro and unlike the A07 Pro. However, the volume knob does not have physical indentations so you have to use visual markings to gauge the volume level. One thing to note is that in my experience, the volume knob had to be turned to at least 12 o'clock position to hear decent volume which I assume is because the potentiometer is a logarithmic and not linear. The NE5532 Op Amps are replaceable just like the case with A07 Pro and A08 Pro. Various other components are also upgraded over the previous two amplifiers so on paper, this amp should perform better which was evident when for example changing the volume while listening. The A08 Pro had a clear audible hiss when changing volume but A07 Max displayed no such behavior. It also suppressed any loud pops or noises when turning on. One thing that I did notice was that there was some cross-talk between the right and the left channel when using the mono-mode. I was able to hear the right channel audio coming into the left channel at quite high volumes but not so much as lower volumes. Overall, I believe this is a very decent and capable amplifier and even outperforms some other recent releases from AIYIMA in certain cases. The value for money is quite good and I definitely recommend this amp if you do not need the Bluetooth connectivity.
Review: Sterling sound for such a low price - in particular, with select Op-Amp upgrades - I never thought I'd be writing about this, but some of these newly released class D amps (that allow for Op-Amp interchangeability), are now approaching audiophile level, class-AB amp sound reproduction. I've been giving many of these Asian-made class-D amps a try over the past few years. With the likes of the Aiyima A07 (the original), the A07 Pro, and now the A07 Max - along with the Fosi Audio BT20A Pro, V3, and most recently, the ZA3 - audio performance quality levels have risen dramatically among compact budget amplifiers - at a pace much faster than I could have previously anticipated. Before I get into the meat of the matter (for those of you interested in this comparison), in my opinion, the A07 Max begins life out of the box with a slightly overall warmer audio tonality to my ears than Fosi's recent ZA3 release. I find that with or without Op-Amp upgrades, the A07 Max has that slightly warmer sound signature (which tends to inch a bit closer to that much desired class AB tonality). As an aside, even the Fosi V3 has a slightly warmer overall sound signature as compared to the ZA3. I found that the A07 Max's sound-staging is pushed more to the rear (behind the speakers), whereas the ZA3's sound-staging is brought much closer to the listener and extends beyond the periphery of the speakers if it's a great recording (at least on my system). A tidbit of note is that with the A07 Max, one can use a variety of different speakers without noticing much of a tonal personality change. However, what I surprisingly discovered was that the Fosi ZA3's tonal personality changed, dependent on the speakers being used. For example, with the KEF Q150's and Q350 bookshelf models, the ZA3 sounded absolutely superb and and I could listen for hours on end! Yet with others - i.e. my Wharfedale, Mission, and Polk bookshelf speakers that I also have on hand - the ZA3 had a tad more of a coolish sound quality to it. The key to remember here is not to use speakers with the ZA3 that have pronounced treble capabilities (or are considered overly bright). With the A07 Max, that is not much of an issue from what I could discern. As to personal preferences for design appearance, I find that the A07 Max's design does not (subjective I know) look as appealing as the Fosi variants. I don't particularly care for the light gray (silver?) front panel which has a tinny and cheap feel to it - but that is just my interpretation because sonically, it far surpasses what one might think about its looks. In my opinion, the A07 Max punches far above it's price-point. This has brought me to say something that I never envisioned saying - and that is, between the Aiyima A07 Max and the Fosi Audio ZA3, they both are now what I would consider to be my standard desktop reference integrated amplifiers. In fact, they have supplanted my Cambridge Audio AXA25 and AXA35 integrated amps as my main reference units. With the Cambridge amplifiers, their size alone are some 8-10 times the size of the Aiyima A07 Max or the Fosi Audio ZA3. I've placed the Cambridge amps back in their respective boxes and will be selling them soon. I guess you could say that's high praise enough. The A07 Max music is a tad less "airy" than the Fosi V3 or ZA3 (where the latest Fosi amps tend to shine), however, its bass capabilities are about on par with the ZA3. However, in some cases, the A07 Max can project a bit too much bass. Highs such as can be found with stringed instruments in a full symphony orchestra, come through with a silky sheen in good recordings. I virtually get lost in the music from good quality recordings - those performances being characterized as highly immersive and musical. Every once in awhile, I have to remind myself that I'm listening to this diminutive box of an amp. More so, I can listen for hours to the A07 Max without experiencing listening fatigue - and yes, the same holds true for the Foxi Audio ZA3. Now here's the one variable to remember - and you have to determine if it's worth it to you to upgrade. I tend to change out the Op-Amps in most of the class D amps that have that feature. I changed out the 2 Op-Amps in the A07 Max, removing their generic cheap NE5532 versions (often used as the stock Op-Amp in most class D amps), with the more expensive discrete Sparkos Labs SS3602 versions. I've also used (and tested) the MUSES02 IC-based Op-Amps - and all sounded absolutely superb, and my comments in this review are based on my trying and using all of these Op-Amps. The upgraded Op-Amps elevated the audio qualities on the A07 Max quite noticeably - read "expanded sound-staging, smoother transients, warmer sound, increased depth and dynamics." More so, in my opinion, changing out the Op Amps to versions from either Sparkos Labs, Burson, or MUSES, brought the A07 Max more in tune with what a class AB amp would sound like. So do I recommend the A07 Max? A big time "hell-yes," I do - with a full 5 stars! Times are a changin' as they say. No longer does one have to spend $500 - $1000+ or so to get a decent audiophile level of amplifier. The likes of Aiyima and Fosi Audio (and a few other brands) are turning heads for less than $100 USD, and that's a good thing - actually, more so, that's a remarkable achievement! If there is one area that I would change, it would be with the appearance of the A07 Max. The Fosi units - in particular the V3 and ZA3, have a more refined (and higher quality) look to them, whereas the A07 max - for some odd reason - still feels a bit cheaper in both appearance and touch (particularly the front panel area). Of course, this is subjective on my part. I would also hope that Aiyima adds balanced inputs in one or more of their future releases if they want to remain competitive, and I bet they will in their next release of this particular style of amp. It is obvious that Fosi Audio and Aiyima are in competition with each other, trying to play leap-frog with their similar releases. It would be nice to now see Nobsound/Douk (really the same company) do the same thing. Choices are nice to have - but in the end, it is the sonic performance of a given amp that will determine a winner. Equipment-wise, I listened to this amp through the likes of the KEF Q150/Q350 bookshelf speakers, along with the Wharfedale D320 and Mission LX2 models. DAC's used were the iFi ZenDac V2, various Schiit DAC's and Head amps, Topping D10S, and the JDS Labs Atom DAC X. Cables used included Audio Quest interconnects, along with 10 gauge banana terminated speaker cable from Blue Jeans Cables. All music came through with a pleasant sense of musicality, great definition, and separation of instruments (and delineating the sound-stage properly). In the end, your mileage may vary of course, and who would I be to argue.

### ⭐⭐⭐⭐⭐ Build Quality. Impressive Performance.
*by M***A on September 15, 2024*

I have always appreciated/enjoyed high quality sound systems. First time considering using mini Class D power amps; did not know they existed. Chose the Aiyima A07 Max because of upgraded quality parts and design, along with good reviews. Using the A07 with Dell PC and Realtek High Definition Audio. I was using an aging Klipsch ProMedia 4.1 system; problems with it's amplifier and bass speakers. So I thought I would try and reuse the perfectly good four Klipsch satellites; 2 each channel. Was not expecting much low end response. If needed, might get an Aiyima DAC-A2 Headphone Amplifier DAC with Bass Treble Controls. Started off with just the A07 Max and the 4 satellites. Very clear/clean but not much bass, as expected. New idea; dusted off some vintage Acoustic Research AR 206HO bookshelf speakers (6" bass/midrange with tweeter). Made the world of difference. It was the quality of the speakers, not the A07 Max lack of performance. Great at all listening levels; full response solid sound. I am not saying it's in audiophile class, but for the cost, build quality, performance and value, it's impressive. This is not the ultimate setup for a computer, but starting to think I prefer this flexible type of configuration over the "all in one" choices, e.g., Klipsch ProMedia's 4.1. For reference: Computer music library in WAV format. Streaming movies; full sound effects and very clear dialogue. Using triangle speaker placement; speakers angled to center. Great separation and definition; listening to studio mix moving from channel to channel (audio panning). No amplifier noise in stand by mode. When pushed, stays cool. I definitely will not need DAC or different Op-amp. Aiyima A07 Max is perfect for my application.
