For low volume listening? Yes
For the Fosi TB10d amp this made a useful difference. Yes it can crank up the volume overall but it increases clarity at lower volumes (seems to me).

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.

Best Way To Get Full Power Output From Your Amp
This is what you need if you want to get the most from your Fosi amps. IMPORTANT: make sure you particular amp is rated for the PS. Not all Fosi amps can take 48V.

Overpriced, but great power supply!

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.

Nice upgrade
I swapped this 48V supply for the 32V one that came with my BT20a Pro... It made a surprisingly noticable difference in the dynamics of the sound... It did make the amp run warmer... I added a cheap silent USB powered fan to keep the temperature at roughly 80-85F.

Super upgrade voor Fosi versterker
Wat een verbetering t.o.v. de meegeleverde voedingsadapter. Klank stukken beter, meer vermogen van de versterker. Geen ruis of vervorming, kan ganse dag spelen zonder oververhit te raken. Had dit gelezen op een forum over Fosi versterkers en vergelijkbare toestellen. Klinkt even goed als mijn Denon en Yamaha nu. Echt een super aanrader, een upgrade om U tegen te zeggen en dit voor een prijsje. Top.

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
