AIYIMAA07 MAX 2 Channel Stereo Amplifier Home Audio 300 Watts x2 Power TPA3255 Class D Mini Speaker Amp Bridgeable Mono Stereo Desktop Amplifier 600Watt With 3.5mm Output Integrated HiFi AmpClimatePartner certified

At this price point I want expecting much and I was very pleasantly surprised. I'm using a Wiim Mini streaming Tidal paired with Wharfdale diamond 9.1 speakers. The sound is accurate and clear. Bass is decent and it can fill a small room. It's a smart uncomplicated little box with solid banana connections for the speakers and a simple on off volume. Love it.

Bought this largely on the strength of the recent Audiosciencereview. I'm driving mine from a pre amp and can control the balance remotely . I believe Amir was less happy with the integrated balance due to the on board pot'. I've not got 'Golden Ears' but to me the sound quality is very good considering the price point. Be aware there's no trigger in remote feature which for some (myself included) might be an issue. Still great value for money, my recommendation.

Lots of positive reviews of the A07Max here and I concur but one feature that I must have is headphone connection. The amp does not have this. I am glad that it is possible to connect a Bluetooth transmitter plugged into the Aux output at the back. Turn down the main Volume knob as this has no effect on the Aux. Actually there is no need to turn the amplifier on at all! Any source (tuner, cd, turntable not needing phono stage, etc) plugged into the amp can be heard through Bluetooth headphone without turning on the amp.Now I am happy (and my good lady too) enjoying the amp using my headphone.

Compact, but gets slightly warm even with delivering circa 100W into 8 ohm.Currently using a 48V PSU, as the 32V is too quiet.I was expecting a louder volume with the amp bridged, but as the supply is on +48V and not +/- 48V, the only advantage bridged is when driving more speakers in parallel.Would recommend trying the amp with a pre-amp, as no clipping even on max volume.For price, size and sound, well worth it.Just a note for others, by going from a 36V supply to a 48V supply you can double the available power as power equals (V*V)/R. Just make sure your 48V supply can deliver at least 7-8 amps, otherwise it will cut out if only rated at 5 Amps as you get close to limit. If driving into 4 Ohm speaker then a 36V 10 amp supply should be fine.

I desperately want to get a second one to bi-amp my small hifi system but can't afford to at the moment, so much has been written about the sonic abilities of this amp but I can confirm everything positive written.I use it as a power amp as volume is controlled via my preamplifier, absolutely faultless can't wait to get my second one real soon hopefully, highly recommended.

Plenty of power on hand here with the AO7 Max. Very well made Class D. Straight out of the box the amp sounds great, fairly balanced with good vocal presence and will probably .satisfy most people’s expectations.

Compact and easy to use. Just the stereo input and output with simple speaker outputs and a single volume control. Presently have this connected to a pair of Kef Egg speakers for “quiet” listening and the sound is very good, however, there is no way this amp produces 300 watts. The output is closer to 7.5 watts. As an experiment I have tried this with 3 other pairs of speakers, Monitor Audio, Yamaha and Wharfedale and this amplifier struggled. Either I have a faulty unit or the way the wattage is measured is in error. In my youth I was a singer and used a 100 watt PA system and was often asked to “turn it down a bit”. Back then in the 1970s 100 watts into a pair of 200 watt PA speakers was loud and rarely needed more than half volume. This nebulous modern manner of describing amplifier output is in my opinion dishonest and should be discouraged. What is wrong with stating the actual output in actual watts. Perhaps decades of listening to very loud music has caused very damaged hearing requiring hugely inflated output figures.If this amplifier had been accurately described with regard to its output it would be incredibly useful in my system as all I want is a simple power amplifier that takes sound from my mixer and amplifies it.In other words “Keep It Simple”.Update, 30 Oct 2024:Despite earlier misgivings, I now have 2 of these amplifiers and am about to buy a third one. I have been rearranging and further rearranging my study for some weeks and have made discoveries galore about these little amps. I still don't know how the makers come up with their 300/600watt power output, they did try to explain it to me but it was beyond my understanding, however, my very clever younger electronical engineer graduate brother told me that on this type of amp it has to do with the amount of power you put into it and the resistance of the loudspeakers. So I gave it more power and used lower resistance speakers and wham bam thank you mam, I have the sound I want. No bleurgh-tooth on these which is great because I have never got it to work, ever. Then there is the daisy chain facility, these have a stereo RCA input and a mini stereo jack Aux output...so, I plug an output lead into the RCA input into an second amp, then I can go from the second to a third and so on...each amp will pun a pair of speakers, so three amps give me 6 (3 pairs of) speakers...so I can combine the dynamics of my Wharfedale 10.1, Yamaha and Kef speakers into quite a pleasurable (well, to me it is) sound. The Wharfedales have an amazing bass sound so no subs needed here...I don't like wooly woofy bass, so the hard Kevlar cones on the Wharfedales are spot on for me, with the addition of 'bungs' in these speakers. All controlled via an Omnitronic PM444 usb mixer. It has taken a while to get there and a lot of tweaking plus the addition of good quality cables to get it sounding right and a fair bit of cartridge experimentation as well.

Firstly let me say I didn't buy from here. I've had it for over a week now and I'm impressed. If you've read about channel imbalance forget it. I ran a channel test video thro it and both channels are at the same level. 36volt power supply is ample for my living room and will drive it louder than I can stand. Using a power breaker to turn on and off and no thump now I'm not killing my dac at the same time. Won't bash on about sound but it's clean and detailed and very pleasant to listen to. Audio out thro the 3.5mm jack stays on when power is off so it's ideal for running into another amp for music in another room (in my case cooking in the kitchen).
