A08 PRO TPA3255 Power Amplifier Bluetooth 5.1 with VU Meter 300W+300W HiFi Class D Stereo Digital Audio Amp 2.0 Channel Amplifier for Passive Speaker Home Audio

Using this to run some outdoor speakers on our boathouse, seems to have some decent power and with good speakers, sounds great. Like this amp enough to buy a second one!

I want to play music in my bed room so I need 2 speakers and 1 power amplifier. My friend bought Aiyima A08 some time ago so I listened to his equipment and I am quite satisfied with A08’s sound quality. Now Aiyima 08’s price has increased a lot so I want to find a cheap alternative. I know Aiyima A07 is good but it doesn’t have any DAC interface or Bluetooth receiver and I have to buy a pre-amp or a DAC to use with it. Therefore, I want to try A08 Pro, which has a reasonable price and a Bluetooth receiver. I am not sure whether I need a DAC so I borrowed my friend’s DAC that costs about $190 to have a test. The build of the A08 Pro looks nice and although it is small, it feels solid and its weight is not very light. The sound volume level meter looks pretty cool. I use Sony SSCS5 speakers and an Android cellphone to work with A08 Pro. To my surprise, A08 Pro supports LDAC codec for Bluetooth, which is the highest quality audio codec for Bluetooth. The pairing is simple and the sound quality is awesome! The sound has a lot of clarity and details. The bass is pretty powerful and treble is also nice. I feel the bass from my friend’s A08 system is a little bit stronger in bass but I don’t think it is because A08 Pro is worse but because my friend’s speakers have 6.5 inch woofers, which are larger than Sony SSCS5’s. Actually I even feel A08 Pro has louder volume than A08 so it can play high dynamic range music easily without much effort. The tone controls are pretty effective. Frankly speaking, although A08 and A08 Pro have the price difference of $60, I don’t think A08 Pro’s sound quality is any worse. When I turned the volume of the cellphone to 0 and turned the volume of A08 Pro to maximum, I could hardly hear the noise from the speakers. Then I compared the sound quality of Bluetooth LDAC input and the sound quality using USB through my friend’s DAC and A08 Pro’s Aux input. I used the same lossless music file from the same Android cellphone. Maybe my ears are not sensitive enough but I cannot tell the difference of the sound quality through A08 Pro’s Bluetooth receiver (using LDAC) and through A08 Pro’s Aux input from a $190 DAC (using USB). Since I don’t need to connect this A08 Pro to optical or coaxial digital input, I believe I don’t need a DAC at all! Summary: A08 Pro is a great amplifier that has great sound quality at a very attractive price. If you don’t need optical or coaxial digital input, you can use this without a DAC but still get awesome sound quality through Bluetooth LDAC codec. Pros: Good sound quality LDAC codec for Bluetooth (actually I haven’t found any other similar priced amplifier that has a Bluetooth LDAC codec) which is the highest quality audio codec for Bluetooth Extremely low noise. Easily upgradable through replacing the AC adapter with a higher voltage and higher current rating power supply Cons: At this price level, I almost cannot find any issue with it. Maybe in future Aiyima can set a passcode for Bluetooth so that no one nearby can “rob” my Bluetooth connection?

Excelente potencia y calidad de construcción este pequeño monstruo es el que levanta dos bocinas Micca MB42X G2 y lo hace de manera excepcional. Yo lo utilizo básicamente para escuchar música por medio de bluetooth en formato LDAC. Por este precio dudo que encuentres algo mejor lástima que no tiene control remoto eso es lo único que le falta pero bueno por el precio está más que perfecto.

The only improvement would be a remote, or perhaps one that controlled both the pre amp and this excellent value for money and very good looking little power amp. Works extremely well with a pair of FAQ car speakers, to much improve the sound of TV and also with a pair of Polk indoor/outdoor speakers. An AUS made Whatmough sub-woofer adds excellent bottom end to both applications.

Very good and high quality
