AIYIMA A07 TPA3255 Power Amplifier: 300Wx2 HiFi Class D Stereo Digital Audio Amp for Passive Speaker Home Audio (A07+DC 32V Power Adapter) Review

Flaws It is well known among Audiophilia fans that Aiyima did a fantastic job integrating Texas Instruments' TPA3255 into their A07 amplifier. As the big brother of the A04, to which the TPA3251 belongs, the additional functions are no longer required, which not only lowers costs but also reduces unnecessary and unwanted internal electrosmog. For example, Bluetooth, which is NOT offered on this model or the A04, has been known to degrade sound quality even when not actively used. Don't take my…

This is my first experience with inexpensive Class D amps. My last full range Class D amp was with a more expensive amp (about 10 times the price of this one) about 15 years ago, and still is. That's what kept me from Class D for so long. It has none of the flaws of my previous attempt. I don't yet know what its longevity will be, but this amp runs silently with no inputs and seems to play my music the way I expected it to. I can't find any compromises in the sound quality compared to my much…

Totally exceeded my expectations. The Aiyima device uses Texas Instruments' TPA3255 chipset, which is really at the heart of what makes these little devices so good. This magic allows for respectable performance from a truly tiny and portable device. In my testing, I paired it with an upgraded Tube-M1 Bluetooth amp with upgraded op amps, power supply, and upgraded tubes. This was paired with an Iphone 11 running Tidal Masters and the results were really impressive. For testing I first used an…

This is the best sounding mini hi-fi amp I have ever heard and it doesn't even come close. The level of detail and distortion-free articulation you hear at the top end of the volume simply doesn't exist in other Class D amps. I expect the TPA3255 will become the industry standard over the next few years, displacing the TPA3116 as the benchmark for mini amps. After listening to this amp I started looking for other information and reviews about it. Suffice it to say that a big hit on YouTube is a

All reviewers can only reflect their subjective opinion. So please take my opinion of this little amp with a grain of salt. Bought this amp based on the many positive reviews. I've tried many Class D amps over the past decade, including some expensive ones. All previous disappointments. Most of the time they were too bright for my liking. After hooking up this Aiyima amp to my living room system, paired with an efficient set of Klipsch kg4 speakers, I tested the amp across many genres of music.

Test device • Sound source: PC with Asus Essence STX II audio card with stereo cinch pre-out • Speakers: PSB Image 25, stereo pair. This amp is known to not deliver 300 watts per channel. It is not uncommon for an audio electronics manufacturer to list specifications that come from a particular component rather than the ratings of the entire circuit designed and built. The TPA3255 amplifier chip has a peak power of 300W for a very short period of time, but under the best circuit design…

A few days ago I received the AIYIMA A07 TPA3255 power amp. I hooked it up to my usual gear which looks like this: - Dento BLT-HD bluetooth receiver - Denafrips Ares ll DAC - Linn Audio LP12 turntable - Toshiba SD9200 CD player only used as CD transport - Aiyima T5 preamp (great combo) - LUMIERE Vaccum tube preamp and phono stage - LAMM hybrid preamp L1 - Woo Audio headphone amp/preamp - Denafrips Hestia preamp - Musical Fidelity 3A preamp. Compared to the following power amplifiers: - Denon…

A pair of *genuine* OPA1656s are an unbeatable and must-have upgrade for the stock NE5532 op amps. I have no regrets after rolling this amp. Now A07 gives a very pleasant, relaxed and analogue, almost vinyl-like music sound! The bass performance is also noticeably improved. The budget class D buff is now improved and redefined by Ladies and Germs! Unfortunately, most if not all of the reviewers who criticize the amp's lack of tonality, lack of soundstage, etc. have not updated the A07 op amps…

Short and simple - Amazing little amp for the money, don't think twice and try it! + Watts per channel in stereo. If you are interested, you can find all the details in the TI data sheet. - The volume control is very useful, I usually keep mine about halfway and control the power through the TV or preamp. - I use heavy RCA cables but the amp remains stable, small but well made and good looking too. The 4mm banana plug is ideal for mounting the speaker. Small in size but still enough power to…

I rarely post reviews on anything on Revain or anywhere else but I absolutely loved this purchase. A few days ago I received the AIYIMA A07 TPA3255 power amplifier. I hooked it up to my usual gear which looks like this: - Dento BLT-HD bluetooth receiver - Denafrips Ares ll DAC - Linn Audio LP12 turntable - Toshiba SD9200 CD player used only as a CD transport - Aiyima T5 preamplifier (excellent combination) - LUMIERE vacuum tube preamp and phono stage - LAMM L1 hybrid preamp - Woo Audio…
