Great with the Fosi ZA3
These are great with the Fosi za3 amplifiers. Makes the bass more solid and controlled and the vocals more dynamic. I have 4 of them each running a za3 as a monoblock, quad amping a difficult to drive set of Neat speakers. Really good.

Annoying
Comes with USA power lead,other than that it's a power supply.

NOT FOR FOSI V3 MONO BLOCK AMPS!!!!!! WARNING!!!!!!
WARNING****Do not use for Fosi audio V3 Mono Blocks****WARNING Hissing on line in! Picking up every single sound from the TV picture changing also. Changed back to old filtered PSU twin and problem solved. Items returned for a refund. This information was not in the reviews when I searched so I'm adding it!

Clear grounding issue with this power supply
I'm using a fosi audio bt20a pro and decided this would be a decent upgrade for it. Unfortunately it plugging the amp into this power supply caused a high pitch squeeking to be emitted from my unit. Definitely does not occur with the standard included power supply, seems consistant with ground loop interference.

Terrible!
I bought two of these to use with 2 Aiyima A07 Max configured as monoblocks. These worked perfectly with the supplied Aiyma 36V power supplies, but with the 48V GaN supplies emitted a loud, high pitched noise through the speakers. I am returning these to Amazon.

Zeer goede voeding, erg blij mee, zit achter een Douk A5 en het laag is veel stakker.

Not much larger than the less powerful standard 5 amp non-GaN power supply. Wish this upgrade was provided as an option when purchasing the amplifier rather than an expensive addition.

Ne ho presi due per alimentare due Fosi V3 mono. Compatibilità e funzionamento perfetti. Non sento stravolgimenti, forse ora il suono e leggermente più corposo, comunque questione di sfumature.

Aiyima nous offre ici une des premières alimentation GaN disponible sur le marché à destination de ces amplis à base de TPA3255 soit les gammes A07/A08 et surtout son dernier gros bébé le A70. Cette alimentation fonctionne en 48v pour une intensité maximale de 10 ampères ce qui va permettre à tout ces amplis de fonctioner de façon optimale lors des pics de consommation sur certains morceaux exigeants. Cet ampli au nitrure de gallium peut fonctionner avec des tensions plus élevées que le silicium et comme on n’a pas besoin d’abaisser les tensions, cela permet d’avoir moins de composants dans un chargeur. Nous obtenons donc un chargeur costaud qui chauffe très peu, capable d'alimenter ces amplis au maximum de leur possibilité. Cette alimentation est donc une des premières du genre. Pas de bourdonnement, pas de ploc ou autre bruit douteux en fonctionnement. Un bon investissement pour celui qui souhaite tirer le maximum de ses enceintes. Testé avec le A70, les graves sont particulièrement bien tenus, et le son parait plus ample qu'avec l'alimentation 5 ampères. Pour moi un bon achat.
