AIYIMA DC48V 10A GaN Power Supply Adapter Amplifier Power Adapter Converter AC110/220V For TPA3255 Stereo Class D Amplifier A07Premium & A07 MAX & A20 & A80 & A07PRO Integrated Amp

The general concensus on the 'internet ' is that you would only see a benefit over , say , a 48v 5a on something like an Aiyima A20 would be at super high volumes where the small units couldn't supply the juice . Keep firmly in mind that most of the people making these claims run old AV amps , place their speakers on their Nan's old sideboard and listen to Bruce Springsteen MP3's off a phone . In other words...do not listen to these people . Even at moderate volumes this PSU 'unlocks' detail and particularly bass layers you had no idea were present in recordings. Seriously . Essential upgrade for the Aiyima A20 . Doesn't make the amp get hot either , might do on other amps .

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.

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

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.

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.

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!

Sin problemas. Aporta la tensión y potencia requeridos. Formato más grande que la de 5A, con lo cual si está en lugar visible será más voluminoso, pero compensa sin duda

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

Alimentation indispensable pour les petits amplificateurs de classe D. Branché sur un Ampapa D1, l'alimentation d'origine en 48V 5A est déjà très bien, mais pour les tenues en puissance, ce 10A apporte la dynamique supplémentaire, et la réserve de puissance à volume élevé. Côté sonorité, car oui, l'alimentation soignée en amont d'un ampli est importante, j'ai tout de suite ressenti un bas médium plus présent, des basses bien tenues, et des aigus moins durs/acérés. La profondeur de scène est également meilleure. Pour conclure, et ce n'est que mon ressenti, car cette alim a un coût, ça ne transformera pas votre système. Mais si comme moi vous avez l'oreille fine, cette alim en vaut la peine.

Big and heavy and tough. No heating issues, does perfectly what it is meant for.

Buen prodicto
