Review: Superb Value, Exceeded All Expectations - The AO7 2-channel power amplifier has become a classic in the "ChiFi" budget audiophile universe. This new "Premium" edition has made an already great value even better. Aiyima has redesigned the amp with better quality internal components, enhanced heat dissipation, a better layout for the rear side connections, and improved cosmetics. It still has all the original virtues, with plenty of power for even power hungry speakers, great sound with no noise and highly detailed transparent sound, a pre-out and a volume control, user-changeable op-amps, etc. You can push even more power by using a 48v power supply, but I am finding the stock lower voltage PSU is all I need. I can't get over how well these little powerhouses stay cool to the touch even after a full day at high volume. I have one of these running a near field desktop set-up, and I have dedicated another to Atmos height speakers in my home theater. I have already ordered a third AO7 Premium for a 2 channel music system in my reading room, and I expect I won't stop there. The A07's are outperforming (and therefore replacing) much more expensive amplification I have owned and appreciated for years. These tiny amps are certainly the most bang for the audio buck you are ever likely to find. Highest possible recommendation!
Review: LOVE this amp! Tinker's delight! Never knew what a little change can do - TLDR; ELAC Debut 2.0 + Aiyima A07 + OP275GPZ Op Amp DIP = you'll thank me later. I have an IOTAVX amp with Triangle Borea BR03 combo that I compare this with. The IOTAVX combo has more deeper bass and sound stage but really not by much... I love both. Let's just say had I only gotten the ELAC Debut 2.0 + Aiyima A07 + OP275GPZ, I would have been really satisfied. Heck, I wouldn't even know which combo I pick if I HAD to choose.. So yea.. wow! Also, I have very sensitive ears due to being young and dumb standing next to a speaker in a club for hours and not realizing that I was going deaf when I got out of the club. Now whenever I hear speakers with too much pressure from bass my ears go into a fritz and it sounds like a broken speaker. So I can only buy speakers that don't make my ears hurt. Some no-no brands for me were Creative Gigaworks, Edifier S2000MKIII, Fluance Ai41 to name a few. Triangle Borea BR03 and ELAC Debut 2.0 is great for my ears. Background: I bought a set of ELAC Debut 2.0 B5.2 Bookshelf Speakers during Christmas cause it was on sale, originally I was only looking for a tiny computer speaker that could make some noise when I was playing games but the sales and thought of getting something good made me go down this rabbit hole. So I had to look for a cheap desktop amp cause I didn't want to take up too much space.. saw the Aiyama 07 amp and read the reviews, sounded good. Powerful enough for any speaker and small footprint. Then one particular review caught my eye.. they changed Op Amp DIP and the sound made a huge difference. Being a tinkerer I couldn't resist. Scared of breaking the amp? Don't be, it's pretty easy to open.. just use one of those L shaped hex wrench and unscrew the top 2 screws of the amp. There's a small phillip screw in the back that you need to remove. Then loosen, don't completely remove the bottom front with the hex wrench and you can pop the top piece right off. Use a mini needle nose plier to remove the 2 Op Amp DIPs that are located near the front. Note what direction the half rounded side of the DIP is going into the sockets. Slowly pull upward without squeezing the plier too tight until you loosen it. There are 2 of them. Pull them both out. Now the hard part, putting the new OP275GPZ in. Just use the plier to slowly lower it down into the holes but MAKE SURE you are matching the side that has the half rounded (as opposed to the straight edge side) down on to MATCH the drawing (white layout) on the board. If you put it the wrong way and turn on the amp, you'll blow it to smithereens. It's easy to match up though.. just pay attention and look at the drawing on the board. Anyways, after you have inserted both.. close it right back up and enjoy! Comparison of Op Amps: Based on reviews that people left on Aiyima A07 review page, I did AB testing on a few Op Amps. 1. First original amp as-is. It was okay, Nothing special but powered the speakers okay. I thought maybe the speakers were only okay. 2. So, I bought LME 49720NA NSC Op Amp DIPs ($11 for 5) cause people said this was pretty good upgrade. But man.. it sounded like the left side was softer than the right and I had to +loudness on the left side to sound equal. Played it for a bit just to make sure I wasn't hearing things.. nothing special in separation of instruments, no sound stage as a matter of fact. 3. I finally tried the OP275GPZ ($15x2) and if this one didn't work, I was going to go all out and buy some Sparko SS3602 Dual Discrete Op Amp that people were raving about but it was significantly more expensive ($80 with 15% off). LUCKILY, I didn't have to go that far as to buy the Sparko.. curious as to what it might sound like but i don't wanna use that much money to test something. Anyways, These OP275GPZ are INCREDIBLE. The sound separation or sound stage from these ELAC is like from above your head to about as far as your arms can reach. There is very very clear separation of each instrument. And it sounded louder than all the previous DIPs that I tried. This one is just amazing. In fact, I think I'm writing this review just for myself so I won't forget what I did when the Aiyama breaks a few years down the line. You will hear a huge difference.. I'm re-listening everything now and it's just AMAZING. Enjoy! I will be leaving the same review on OP Amp and speaker review pages.

### ⭐⭐⭐⭐ Not a bad little amp.
*by Q***E on July 31, 2025*

Overall, this is an impressive little amplifier. Sound quality is very good, and the design is acceptable. I will probably get another one from this manufacturer. Tested on Klipsch R-41M Klipsch SB1 Alesis Monitor One The sound quality is very good even at higher volume. I did get what sounded like a little bit of ringing in the high frequencies on the Alesis Monitors. I was unable to reproduce this ringing using my Class A/B Sony amp. To be fair, it was only on one song that has a lot going on in that range. PROS: Sound quality is very good. Very Little Heat when running at near full volume. Offset binding posts are a nice feature. They make it easier to put wires on it. Upgradeable Op Amps due to socketed chips. Very compact. The volume control is very nice. It is a click type potentiometer. Pre-Out CONS: Binding post are pretty much garbage. They don't support 16 gauge wire. If you are using this with larger wire get a set of banana plugs, don't mess with the binding posts. Not anywhere near the 300x300w that they claim. With the power supply included, maybe 75x75W I very much dislike the toggle switch for power. I think a push-button would have been better. Person Preference here, but it just makes it feel cheap.
