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.

A Class D mono/stereo amplifier with an upgrade path for delivering maximum power

I purchased a pair of the Aiyima A07 Max amplifiers for use with a WiiM Ultra control preamplifier. The A07 Max amplifiers performed well with the WiiM Ultra control preamplifier using the line out from the WiiM Ultra. I compared this combination with the WiiM Amp Pro. The WiiM Amp, WiiM Amp Pro and WIIM Vibelink Amp each support digital optical input, that is how I prefer to listen to music via the WiiM Ultra to the WiiM Amp Pro versus the line out/line in (RCA) connection. The Aiyima A07 Max does not provide an optical input, only one pair of L/R RCA connections.The Aiyima A07 Max can be set to stereo mode or mono mode. You can start out with a single A07 Max amplifier set for stereo mode. You later can add a second A07 Max amplifier, set both A07 Max amplifiers for mono mode in a two channel system.Mono mode can provide increased channel separation. Using two amplifiers in mono mode unburdens a single power supply from having to supply power to both channels while maximizing dynamic headroom. As excerpted from the A07 Max owner's manual maximum rated power with the included 36V/6A power supply (in stereo mode) is: 107 Watts x 2 channels @ 4ohms, 100Wx2@6ohms, 94Wx2@8ohms. (In mono mode) the maximum power rises to 190 Watts x 1 channel @ 4 ohms, 150Wx1@6ohms, 118Wx1@8ohms.A single Aiyima A07 Max amplifier in stereo mode provides very engaging, dynamic sound. I actually prefer the sound of a single A07 Max amplifier versus a pair of A07 Max amplifiers set to mono mode for some music. In stereo mode the input sensitivity of the A07 Max is ~3dB higher than in mono mode. The damping factor, not stated, will be reduced by half in mono mode. To be sure, in mono mode, the channel separation is improved, the midrange frequencies come through with better instrument and vocal definition than in stereo mode. Still, in stereo mode the A07 Max draws me in with its very punchy, musical bass performance; The Allman Brothers Band sounds great when using a single A07 Max amplifier in stereo mode. In comparison , a pair of A07 Max amplifiers in mono mode sound more refined but not as ready to rock. A single A07 Max amplifier is a great way to start listening. You can always add a second A07 Max amplifier.The A07 Max amplifier has no tone controls. I prefer to use the WiiM Home app's equalizer functions (both graphic and parametric equalizers are included) rather than conventional bass and treble tone controls. The volume knob on the front of the A07 Max is also the power switch. There are two blue LEDs on the front of the A07 Max. One LED is on the left and the other LED is on the right side of the volume control. These LEDs indicate whether the amplifier is set for stereo mode or mono mode. There is a recessed Stereo/Mono mode switch on the bottom of the A07 Max. Among the small, inexpensive Class D amplifiers the Aiyima A07 Max is noteworthy for being able to be switched between stereo mode (BTL) and mono mode (PBTL).I found the A07 Max sounded better when set to mono mode, including bass extension and tightness of the bass notes. In mono mode, in addition to having to connect one pair of speaker wires to the binding posts labeled "+ Mono Mode -" you need to connect one channel of a typical dual RCA cable to the A07 Max's RCA white colored connector that is labeled "L". If you accidently connect the RCA cable connector to the red RCA connector that is labeled "R" you won't get any audio output from the A07 Max amplifier.Compared to some other small amplifiers, the speaker binding posts on the A07 Max are a bit larger (but still made of plastic and metal, not all metal) and are staggered with the lower connectors shifted slightly to the right for easier access. I recommend using banana plugs to connect the speaker wires. I use the Sewell deadbolt banana plugs (sold on Amazon.)There is a 3.5mm Aux Out connection next to the RCA connectors that is a pass through from the RCA inputs terminals The Aux Out level is not controlled by the volume control on the A07 Max. For connecting to a powered subwoofer I use the WiiM Ultra's single RCA subwoofer output connection.A key differentiator between a two channel audio system based around the WiiM Ultra with a one or a pair of Class D amplifiers (such as the A07 Max) versus using just the WiiM Amp or WiiM Amp Pro is that there is no upgrade path with the WiiM Amp/WiiM Amp Pro that does not involve replacing the WiiM amplifier unit with another amplifier unit. [Update: WiiM has introduced the WiiM Vibelink Amp as the matching amplifier for the WiiM Ultra. You could start out with or upgrade to the WiiM Vibelink Amp from the WiiM Amp/WiiM Amp Pro for ~3db more headroom and maximum power (100WX2@8ohms/200WX2@4ohms) when using the optical connection.] From a cost/value perspective a single Aiyima A07 Max amplifier (or a pair of A07 Max amplifiers used in Mono mode) are a viable alternative to one of the WiiM amplifiers. The maximum available power from the WiiM Ultra/A07 Max combination can be increased by adding a second A07 Max unit (while retaining the original A07 Max), in mono mode. You can maximize available amplifier power of the A07 Max by upgrading the power supply.Should you require maximum power from the A07 Max amplifier you can substitute a 48V/10A power supply for the standard 36V/6A power supply. In dual mono mode, a pair of A07 Max amplifiers set to mono mode and a pair of Aiyima brand GaN 48V/10A power supply units (sold on Amazon), each A07 Max amplifier unit can then provide (315Wx1@4ohms, 240Wx1@6ohms, 190Wx1@8ohms). This is significantly more power, (3dB or more headroom and available power @ 4 and 6 ohms) than the advertised maximum rated power of the WiiM Amp or WiiM Amp Pro (60Wx2@8ohms, 120Wx2@4ohms).I measured the temperature of the case of the A07 Max amplifier when using the stock 36V/6A power supply while powered on, while in use. The case temperature was 82F in standby. [It is now July. The room temperature is ~78/79F. The case temperatures of the two A07 Max amplifiers (stacked with the stock power supplies) while actively powering speakers are running ~98 to 100F, warmer than in previous months but not a concern. The WiiM Vibelink Amp, sitting beneath the two A07 Max amplifiers, is in standby with a case temperature of ~95F.] In comparison the earlier temperature readings this spring of the case of the WiiM Amp: 76F, WiiM Amp Pro: 79F, WiiM Ultra: 76F, WiiM Mini: 79F. In comparison the temperature of the case of the Fosi Audio TB10D amplifier with the stock 32V/5A power supply measured 72F. The cooler the better, for longevity. [Update: I measured the standby power consumption of the A07 Max amplifier. Plugged in, switched off, the power consumption measured 0.1 Watt. Powered on, no input signal, the power consumption measured 4.3 Watts. This measurement was for one A07 Max amplifier in either stereo mode or mono mode. A pair of A07 Max amplifiers switched on, with no signal, consume 8.6 Watts.I enjoy listening to the Aiyima A07 Max amplifier powering a pair of Saiyin DS6700M Passive Bookshelf Speakers. The Saiyin DS6700M is a small 2-way passive speaker with a 3.5" woofer & silk Horn tweeter, sold on Amazon. See my separate review of the Saiyin DS6700 speakers.]

Build Quality. Impressive Performance.

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.
