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

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

Perfect for powering your amplifiers for that extra power. Excellent price and build quality - like many of this brands products they deliver on quality and eagerly priced - so an all round winner for me.

Good quality power supply makes my fosi Audio BT20 Amp sound much louder.

Have a fosi V3 used to power a Dayton 300w bass shaker. It came with the 32v adapter which was fine but not getting the most out of my setup. Purchased this 48v adapter to up the power but I can't really tell the difference and would have kept the 32v. However this is not its main purpose and it's probably much better powering speakers with a nice pre amp setup.

As a couple of other reviewers have noted, this 48v upgrade on the 24v or 32v supplies that small digital amps come with, brings much added clarity. Definite improvement on a slightly recessed top end, and removed a sense of ‘compression’ on denser tracks. I wasn’t sure if it would be much of a difference and got ready for some A/B testing. As soon as I heard this power supply in action I knew I didn’t need to do an A/B, the improvement was that obvious. I am using an Aiyima 07 amp (came with 32v 5A supply) to drive KEF kht300 speakers (8 Ω). Very happy with this upgrade.

Really added some much needed bass to my fosi audio v3. Sounds better than my Cambridge audio sr20

Its a very good power supply. Providing power to the Fosi Audio V3 it gave a nice warmer sound than others I have tried.

Works just fine - but no significant improvement in output over the lower voltage unit usually supplied with Fosi amps

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!

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.

Recommended to use for fosi v3, no problems at all for 1 year.

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
