Will it improve sound quality?** A: Max voltage for the BL20A is 24V. This is the limit for the two TPA3116D2 chips, so I would not recommend a 32V power supply. Fosi Audio sells a 24V supply that might "improve" sound with respect to the amount headroom (large swings in volume) you can get without distortion but I doubt you could tell the difference at reasonable volumes. **Q: What is better power supply to use for Fosi BL20a amp? 32v 5a or 24v 8a or 48v 5a?** A: 48v **Q: Bt30dpro is only rated to 36v5a does this supply really work for it? is there a 36/48v 10a version?** A: I bought this power supply for the for the Fosi BT10D it will take up to a 48 volt power supply. My two other Fosi amps will only use a 32 volt power supply. So you must be careful to use the correct unit. Sadly I am not familiar with the BT30Dpro. If you go to the Fosi website they might have additional information. I am sorry I could not be more help. **Q: did it improve bt20a pro quality? if yes which speaker type and watt do you use that make a difference?** A: 48 V power supply improved sound with more clarity and wider soundstage. Speaker type is best at 8ohms. ## Frequently Bought Together - Fosi Audio 48V 5A Power Adapter Supply for Home Audio Bluetooth Stereo Receiver Amplifier Mini Hi-Fi Class D Integrated Amp - Fosi Audio BT20A Pro Bluetooth 5.0 Amplifier, 300W x2 Wireless Amp, TPA3255 2 Channel Mini Class D Integrated Home Audio Outdoor Stereo Receiver with Bass Treble Control for Passive Speakers - FosPower Banana Plugs 2 Pairs / 4 pcs, Closed Screw 24K Gold Plated Banana Speaker Plug Connectors for Speaker Wire, Wall Plate, Home Theater, Audio/Video Receiver, Amplifiers and Sound Systems --- ## 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.gr/products/553223851-48v-5a-power-adapter-supply-for-home-audio-bluetooth-stereo](https://www.desertcart.gr/products/553223851-48v-5a-power-adapter-supply-for-home-audio-bluetooth-stereo) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-08*
