After spending a decent chunk on a system - all new I decided to create (or rather cobble together) one buy scouring the internet.Got these AED 259 - they have a special running, used floor standing Mission M73i speakers, a very old and used Sonos Connect ZP90 (only streamer not amp). The used stuff off Dubizzle and the new amp from Amazon. Including wires (from Pult in Dubai) the whole thing set me back by AED 1134.00Worth it. This amp is great. Initially felt a bit underpowered but then I turned up the treble and bass to almost max. Fixed that.With the ZP90s connected to this I get to hear beautiful music from Qobuz and Spotify on the M73is.I recommend not using the Bluetooth connection if possible- sound quality not that good (as Wi-Fi) and if your is not set to silent mode then even the keyboard clicks can be heard on the speakers.Overall: an outstanding purchase.Will post pictures of the connections soon.April 2023 ### ⭐⭐⭐⭐⭐ Good sound for the price *by on Reviewed in the United Arab Emirates 23 May 2025* I’ve had it for a year and no problems, great sound ### ⭐⭐⭐⭐ reliable *by on Reviewed in the United Arab Emirates 16 March 2025* small but reliable amplifier. it would be better if it is capable of multiple bluetooth connection. ## Frequently Bought Together - Fosi Audio BT20A Bluetooth Stereo Amplifier, 2 Channel Home Audio Component Amplifiers for Passive Speakers, Mini Class D Amp Receiver 200W for Indoor/Outdoor/Garage/Ceiling/Bookshelf Speaker - Banana Plugs with Dual Set Screws,Black and Red Aluminum Shell,6 Pairs - Amazon Basics Speaker Cable, Easy Assembly, 16-Gauge, Bronze, 100 ft --- ## 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.be/products/254857527-bt20a-bluetooth-5-0-stereo-audio-2-channel-amplifier-receiver](https://www.desertcart.be/products/254857527-bt20a-bluetooth-5-0-stereo-audio-2-channel-amplifier-receiver) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-02*
