Definitely improvement over 32V oem adapter comes alongwith......reading reviews i was bit confused but again changing mind i ordered & results were great.....yes fosi audio heat lil bit but that's ok but adapter being cool even after 4-5 hours use. Using QA 3020i with fosi audio....amazing no need to add subwoofer now.

Product is good but no improvement
Only volume became louder but No improvement in sound by switching to this expensive power supply.the tone of the sound actuallyy feels dull now. Am using it with fosi 20d bt pro. Unlike posted on web,this power supply is not the right match. It's better to buy more efficient speakers.

Adaptor costs more than compatible Class-D amplifier
If I want to upgrade my existing Amplifier to have additional power, the adapter costs ~70% of the compatible Class-D amplifiers from Fosi Audio.

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!

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.

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

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.
