DC48V 10A GaN Power Supply Adapter for TPA3255 Stereo Class D Amplifier A07 & A07 MAX & A08 PRO & A70

This is a high value product. The upgrade from the 36v stock brick to this beastie was well worth the price. The A07Max amp class D amps just soak up the current and deliver it smooth and unadulterated with the stock neutral chipset. I have seen frequency graphs and these things are very quiet. Good filters and cables are necessary for any audio. I had to order new female C17 Copper plugs for the Viborg cables as the new GaN bricks do not use the figure-8 style C8 so tack on $80 for a pair. I did not realize how much larger the bricks were until they arrived. I am very impressed. These are value priced and fast-ship. I normally run them for my Dolby Atmos speakers. They double as 300w/8 ohms monoblocks now. 1970 Coral BX-Multi1200e speakers with 1960’s 16/8 ohm NT-3B pro crossovers. Belden 9470 audiophile wiring. Recapped Miflex KPAL and Mundorf Evo Oil caps. 999 pure silver in clear pvc for reach. It takes time for good music to happen. These warm up to cruise after 3-4 hours.

This should be an option when buying the amp.

Purchased to upgrade my Fosi 48 volt 5 amp power supply. Based on price and upgraded design this 10amp power supply brings out more power, dynamics, clarity. No noticeable hum or noise! Live in an area with a lot of cell towers and high power line. Absolutely no problems. For me it’s a great buy and does exactly what Fosi said theirs would do! Can not compare the to different power supplies as I didn’t have two Fosi power supplies. Fosi states that it up rated power supplies can increase power safely as the chip can handle 53 volts 12 amperage with and increase in power with increased need for ventilation. Yes, my amps run hotter so placement should be watched.A small inexpensive computer fan has been used on some of the reviewers will good results. I love the Fosi products. If you want to really hear and feel the increased power do the upgrade. You I’ll need two power supplies for the Fosi V3 Monoblock amplifiers.The manufacturer uses the same chip TI 3355 using the same voltage and amperage as well as adapter in their amplifiers.

These GaN smps are strong, quick, and quiet. I also use an additional emi/rfi dc filter to power two 3e Audio A7 mono class D amplifiers. They never run warm.

Power supply works well with Douk audio A5 pro to give a boost in power wattage.

O. M. G. Use with Fosi audio BT 30D Pro replacing 5A PS. B. O. O. M! FFosi drives: A pair of Hafler M5 reference, sub is Tone Tubby 10" in a Baltic birch box, 3/4" slot port. Does ~<30 Hz. Sub freq rolled off above 70Hz. Ba-BOOOM!

Very high quality, doesnt get warm and no noise from the aiyima a20 amp, you can feel the extra power. Green led shows when its on. Perfect 5/5

Sadly I failed to read the one star reviews in this case and became yet another person to experience an immediate ground loop issue. This power supply is grounded whereas the original one is not. No loop with the original. Immediate hum with this one.

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

Es muy potente, pero pesada y grande, además de no ser totalmente silenciosa (lleva un ventilador que salta según sea necesario). Casi le quito 1 estrella por ello... pero, siendo razonables, la verdad es que en estas potencias no hay casi nada alternativo que reduzcan el tamaño, el peso o que sean totalmente pasivas. Sólo se la aconsejo a quien necesite mucha potencia, porque la "normal" de 5A es mucho más pequeña (ver foto comparativa) y da más que sobrado para un setup de escritorio o una sala mediana (de hecho el Aiyima A70 es la que trae por defecto). Solo para los más exigentes, con altavoces poco sensibles o espacios muy abiertos.

Buen prodicto

Ich habe das Netzteil als Leistungserweiterung für einem kleinen Verstärker gekauft. Das Netzteil wurde nur leicht warm und war leise. In Verbindung mit einer Enegiekostenzähler-Steckdose kann ich die angegebene Leistung bestätigen

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.
