5.0 out of 5 stars 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.

5.0 out of 5 stars 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.

5.0 out of 5 stars 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.

5.0 out of 5 stars Nice upgrade for even more clean power.

Seems to be doing as expected! Very good value!

Adequate, clean power.

I'm using this PSU instead of the 32V one supplied with the Fosi V3 amp. It works well, keeps the amp happy as it powers a pair of older Polk RT5 speakers. Those speakers are neither special, not particularly difficult to drive but their sensitivity is a little low for a pair of bookshelves so they need a bit of power to truly sing.I used this combo for a couple of smaller house parties and this combination was more than adequate to deliver the power needed without breaking a sweat.Recommended!

5.0 out of 5 stars 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!

Fosi Audio V3 sahipleri sahip olması gerekli..

sipariş ettikten 11 gün sonra teslim edildi, kesinlikle V3 sınıf atladı. Odyofil değilim ancak ses kalitesi konusunda bariz netlik ve vurgulu solo seslerde ise hafif boyut kazandı. güç konusuna ben girmiyorum amacım güç almak değildi ama doğal olarak güçte geldi, tavsiye ederim

Reliable

This amplifier is a great way to pump up the sound thanks for the quick delivery

5.0 out of 5 stars Boosts the power for my Fosi Audio TB 10D amp and makes it sound better.

2026-02-13    -Robert J.

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.
