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

Just what I needed to take the Aiyima A07 premium to the next level. This is not going to make the amplifier louder. It is going to make your audio output cleaner less distorted and more defined at all volume levels.

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.

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.

I bought this for an amplifier which came with a power supply but the maker stated that the amp would not put out its full potential watts unless you bought this larger power supply. I get it but when I use the larger power supply I can't tell any difference at preset volumes. I probably need to use a more scientific approach but I'm not that motivated.

If you don't care about sound quality, don't bother. Everyone else,,,, the 48 volt 10 amp is worth every penny.

The good product

I was wondering how such a highly rated item can have a "frequently returned" note at the bottom of the listing. Then Amazon rejected my previous review when I mentioned that the condition of the brick was not at all consistent with what was described. Since I'm expected to bury my actual point deep inside a happy-go-lucky collection of fuzzy keywords in order get past the bot check, the burden of the interpretation is hereby shifted shifted unto you, the reader. Take a look at the included images and decide whether you'd be able to fire this thing up right out of the box based on what's included. The other thing I immediately thought of was the Ferrari from Ferris Bueller's Day Off after it had just been picked up from the downtown Chicago parking garage. Now for some ahem, pleasant keywords: Solid, shiny, well built, high quality, highly desirable, oh, wait I'm still thinking of the red thing with the soft top. I placed another order and will update review if the replacement shows up deserving of a higher rating.

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
