We have professional knowledge in audio software and hardware, combined with advanced production technology, to provide high-quality products and product services. ## Features - Superior Audio Quality：AIYIMA A07 MAX Mini Hifi amplifier uses TI TPA3255 high-performance, low-distortion Class D amplifier chip and NE5532 operational amplifier chip, wafer resistors. Ensure excellent sound quality and stable performance, showing the richness and clarity of music. - High-quality audio components: The mini home audio amplifier uses Japanese capacitors, ELNA and German WIMA capacitors, as well as IT power management chips, large binding posts, and positive and negative power supplies. Create excellent sound quality, more stable in large dynamic music, and stronger sound layering. - Innovative bridged mono design: AIYIMA A07 MAX is a bridgeable mono/stereo desktop amplifier that can be easily set up by simply flipping the function switch on the bottom of the machine. Easily drives 2-8 ohms, comes with 36V6A power supply, Stereo Max output power 8 ohms 94 watts x2, Mono Max output power 8 ohms 118 watts.(Note: You need a more powerful power supply to get the MAX 300W x2 power output, such as 48V/10A). - Excellent design: The amplifier adopts a mini-shape design and combines an air circulation design concept. Ventilation holes on the sides and bottom of the case effectively dissipate heat while preventing damage to internal parts, ensuring optimal performance. The compact body is ideal for desktop use, home audio systems, and office work settings. - Compatible with a variety of operational amplifier chips: A07max power amplifier has rich sound. If you want to experience different sounds, you can replace the operational amplifier chips: OPA2604AP, OPA2134, MUSEO1/02/03, LME49720NA, LM4562, AD827AQ, etc. - Note: Pre-out" level is not controlled by the volume control because the A07MAX amplifier is not an integrated amplifier, so the sound cannot be adjusted when you connect it to "Pre-out".A07 MAX machine preheating an hour or so, the sound quality tone better! - Note: The TPA3255 is a high-performance Class D audio amplifier chip whose final power output is closely dependent on the power supply configuration. Using an incompatible or non-compliant power adapter may result in inconsistent output power levels or insufficient power causing device protection (incompatibility). ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0CJ6TSSY4 | | Best Sellers Rank | 36,368 in Electronics & Photo (See Top 100 in Electronics & Photo) 177 in Hi-Fi Amplifiers | | Brand | AIYIMA | | Country Of Origin | China | | Customer Reviews | 4.4 4.4 out of 5 stars (643) 4.4 out of 5 stars | | Included Components | 1 x A07 MAX amplifier; 1 x DC 36V 6A power adapter; 1 x user manual | | Item Dimensions | 15.3 x 10 x 4 centimetres | | Item Weight | 1 Kilograms | | Manufacturer | AIYIMA TECH | | Manufacturer Part Number | B2D3176F | | Material | Plastic | | Maximum Supply Voltage | 48 Volts | | Minimum Supply Voltage | 48 Volts (AC) | | Model Number | A07MAX | | Mounting Type | Freestanding | | Number Of Channels | 2 | | Number Of Items | 1 | | Output Power | 600 Watts | | Package Type Name | Box | | Product Warranty | A 2-year warranty applies, provided there is no evidence of deliberate damage. | | Specification Met | Tpa3255 | | Voltage | 36 Volts (DC) | ## Product Details - **Item dimensions L x W x H:** 15.3 x 10 x 4 centimetres - **Manufacturer:** AIYIMA TECH - **Maximum supply voltage:** 48 Volts - **Minimum supply voltage:** 48 Volts (AC) - **Voltage:** 36 Volts (DC) ## Images ![A07MAX 300Wx2 Class D TPA3255 HiFi Mini Mono/Stereo Amplifier - Image 1](https://m.media-amazon.com/images/I/51AzO9lef9L.jpg) ![A07MAX 300Wx2 Class D TPA3255 HiFi Mini Mono/Stereo Amplifier - Image 2](https://m.media-amazon.com/images/I/71jjp-9JLWL.jpg) ![A07MAX 300Wx2 Class D TPA3255 HiFi Mini Mono/Stereo Amplifier - Image 3](https://m.media-amazon.com/images/I/71VKXpzmSwL.jpg) ![A07MAX 300Wx2 Class D TPA3255 HiFi Mini Mono/Stereo Amplifier - Image 4](https://m.media-amazon.com/images/I/71a1PITuDEL.jpg) ![A07MAX 300Wx2 Class D TPA3255 HiFi Mini Mono/Stereo Amplifier - Image 5](https://m.media-amazon.com/images/I/71rGFTsGBFL.jpg) ## Questions & Answers **Q: does this come with a power supply?** A: Yes .The package with DC36V 6A power adapter **Q: Can this be purchased on Amazon with the 48v power supply?** A: The A07 MAX package included DC36V 6A power adapter ,but we have sold another DC48V 5A power adapter on amazon, if you want the DC48V 5A power adapter ,you can place the another DC48V power adapter order. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A tiny amp with a big sound *by on Reviewed in the United Kingdom 11 October 2025* Having grown up with hi-fi amplifiers being large and heavy, even for modest power outputs, this tiny amplifier is amazing. It is very powerful and sounds very clear with plenty of punch through my Mission speakers. It uses the Class-D principle, which has been theoretically possible for many decades, but very difficult to make a practical working design. Texas Instruments have pioneered Class-D amplifier integrated circuits, and this amplifier unit utilises one of their best chip designs. Although the unit is very small and quite basic - just a volume control on the front - the sound quality and power you get for a such a low cost is incredible. ### ⭐⭐⭐⭐⭐ Great Bang for Buck *by on Reviewed in the United Kingdom 8 December 2024* 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. ### ⭐⭐⭐⭐ AIYIMA A07 MAX 2 Channel Stereo Amplifier Home Audio 300 Watts x2 Class D Amp Bridgeable Mono Stereo *by on Reviewed in the United Kingdom 20 July 2024* 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. ## Frequently Bought Together - AIYIMA A07 MAX 2 Channel Stereo Amplifier Home Audio 300W*2 TPA3255 Class D Power Amp/Bridgeable Mono Amplifier 600 Watt with 3.5mm Line Output for Passive Bookshelf Speakers+DC36V 6A Power Adapter - AIYIMA DC48V 10A GaN Power Supply Adapter for TPA3255 Stereo Class D Amplifier A07 & A07 MAX & A08 PRO & A70 - GearIT 14 AWG Speaker Cable with Banana Plugs 14Ga Banana Wire for Bi-Wire Bi-Amp HiFi Surround Sound --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/583110733-a07max-300wx2-class-d-tpa3255-hifi-mini-mono-stereo-amplifier](https://www.desertcart.jp/products/583110733-a07max-300wx2-class-d-tpa3255-hifi-mini-mono-stereo-amplifier) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-22*
