AIYIMA 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.

It's still working. Lets see how long it lasts.

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.

Small amps Douk A5 claiming 600 watts with this power supply, how can that be if the 48v 10a power supply only puts out 480 watts, $70. Wasted trying to get the full 600 watts, a more expensive adjustable power supply might get it done.

The good product

I have two of these power supplies hooked up to two of the Fosi Audio v3 mono amplifiers and they really seem to make a difference compared to the 48v/5a power supplies. The mids and lows are more prominent and well separated in my Wharfedales. I was honestly not expecting much of a difference, but I am happy.

On paper, this is an amazing deal. Unfortunately, it makes a buzzing sound at high volumes over my fosi V3, similar to a gnat. It's not super loud, but if you're listening for a black background, you can hear it, and it's a deal breaker. I had the same problem with another 48v10a gan psu, but not with a 48v10a non-gan psu, and not with a 48v5a gan psu. If I stick with the V3, between 48v10a non-gan and 48v5a gan, I'm going with the latter.

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.

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

Buen prodicto

Works as it should
