Fosi Audio 48V 5A Power Adapter Supply for Home Audio Bluetooth Stereo Receiver Amplifier Mini Hi-Fi Class D Integrated Amp

Q: Will this work with Fosi Audio BL20A ? Will it improve sound quality?

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: Bt30dpro is only rated to 36v5a does this supply really work for it? is there a 36/48v 10a version?

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?

48 V power supply improved sound with more clarity and wider soundstage. Speaker type is best at 8ohms.
