It is a great amplifier with some really cool features I never knew I needed. As far as I can tell, it meets or exceeds all its specifications for TDP, power output etc. I will be evaluating this in more detail under different loads at a future date so for now I will cover more of the cool features: 1. XLR is a nice to have. I don't personally have any in my setup but occasionally I have used it for odd or specific setups. 2. The +6db is REALLY nice. Some audio sources are really quiet. The worst offender is an LG TV that automatically drops the volume every 30 minutes if you set it above a certain level in the UI. The trouble is, the TV doesn't actually know how loud the room is so this may be going from a comfortable volume to nearly silent. The +6db allows you to get the full range out if this amp with such sources. 3. The built in crossover is cool. Not used as I have a full equalizer for room calibration but I can think of times it would be useful. 4. The 12V trigger is awesome! I cannot wait to build a custom controller for this that allows it to be switched on and off with the rest of my setup to allow for energy savings. I really only have two gripes: 1. AIYIMA already has a product with the name "A70" which could be confusing. They also advertise this as being used for 7.1 surround setups, but having 8 of this seems like it would require excessive tinkering to get a room to sound good compared to an all-in-one receiver that is programmable. ## Features - HIGH QUALITY COMPONENTS: Class D AIYIMA A70 mini monobloc mono amplifier is equipped with Japanese Rubycon 63V 3300uf filter capacitors, ELNA audio capacitors, German WIMA capacitors and professional high-power single-mode inductors, which reduce the distortion rate to 0.001%, the signal-to-noise ratio to 116dB and ensure a High-power high-power high-power - HIGH PERFORMANCE AMPLIFIER: A70 Mono is designed for HiFi enthusiasts, with rated power up to 300W @ 4Ω with 10% distortion.

Che dire,lo sto usando con l'impianto HT in mono su un subwoofer con 2 altoparlanti 4 ohm da 25 cm messi in parallelo tra loro. L'apparecchietto,per le dimensioni, se la cava egregiamente: pilota il subwoofer alla grande,senza minimamente riscaldare. Si, lo consiglio! ## Frequently Bought Together - AIYIMA A70 Mono Amplifier with PFFB Home Audio Receiver,TPA3255 Class D Amp with Subwoofer for Home Theater Bookshelf Speaker,with XLR & RCA Inputs & Trigger Input - AIYIMA DC48V 10A GaN Power Supply Adapter for TPA3255 Stereo Class D Amplifier A07 & A07 MAX & A08 PRO & A70 --- ## 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.tn/products/658148460-a70-mono-power-amplifier-with-pffb-tpa3255-mini-class-d](https://www.desertcart.tn/products/658148460-a70-mono-power-amplifier-with-pffb-tpa3255-mini-class-d) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-14*
