Good quality product, worked great. This is the required item for the AMPs full power output.
These are the required power supply model to get the full benefit of the Amps output power potential. Produced a clean sound with no noise distortion. They work well, and I seem to be well made. With a power supply you don’t want the cheapest model, especially for fire hazard potential. Always make sure you get the correctly matched item.

Boosts the power for my Fosi Audio TB 10D amp and makes it sound better.
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.

Good Power Supply
It works fine but I didn;t notice much difference in performance of my Fosi BT Amp. I was hoping I would get a little more power out of my amp but it is only marginally louder. It is as distortion free as any amp I have had, I think it is a great littl amp.

It's a power brick
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.

Doubles energy storage of 32V power supply
Doubles the energy storage (10 joules vs 5) over the stock 32V model. Worth the added expense using an MC351 Integrated amp/DAC.

You NEED this!
If you enjoy hearing your music on the loud side and you have a subwoofer attached to the Fosi Audio BT20A Pro, this power supply is a must have! The stock unit provided is fine if you are happy listening to music or your movies at moderate levels. However, this upgrade does make an audible difference when you power up!

Nice upgrade for even more clean power.
Seems to be doing as expected! Very good value!

Only 48V 5A power adapter for Fosi amplifier
I suggest only buying this if upgrading the wattage of your Fosi amplifier. I’ve tried other cheaper brand 48V 5A power adapters, unfortunately they all didn’t work for the Fosi amplifier.
