Meets or exceeds marketing statistics and has cool features! *by N***S on 10 October 2024* Electronics engineer's review will be coming soon (tm) As a consumer, the A70 just works. 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. ## 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.sg/products/657204428-aiyima-a70-mono-power-amplifier-with-pffb-tpa3255-mini-class](https://www.desertcart.sg/products/657204428-aiyima-a70-mono-power-amplifier-with-pffb-tpa3255-mini-class) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-31*
