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

Increases the output to the Fosi B2A Pro. I was amazed at how good my Wiim Ultra to my Kef Q150s sound now! I am more than satisfied with this purchase.

Replaced the stock 36 V power supply on my A08 Pro amplifier with this 48V power supply. Wow, increased overall performance substantially. Brings out the best in my Elac UF5's.

I bought the Fosi Audio TB10D power amp (Improved version) and was pretty happy with it but it needed more power to handle certain type of music. For $60 (price when I bought it, including discount coupon) I couldn't complain. As soon as I heard Fosi made a more powerful power supply I jumped at the chance to buy one.It arrived the next day. I was a little surprised to see it was nearly the size of the amp. I plugged it in. I put on some music, Classical, Rock, Pop, Jazz, and more and found the amp sounded better than ever!Total price is still a steal for what you get.

I bought this because the fosi bt20a comes with 32v. I don't understand why but I think the brick should have been built into the box itself. I'll report back after some use. Still waiting for this and the amp to arrive. Just a little pre complaint.

Worked great as replacement for OEM power supply giving more overhead and more power

Exactly the product I needed and expected.

The product is good, but the shipping and handling for Europe is expensive AF. I paid almost double the price. I don't know how is that possible, because if i order from China i get free shipping, or a very small fee. Also, i didn't get any benefit with Amazon Prime.

Exactly as listed super fast shipping improves the sound of the Fosi BT20A Pro
