## Description

AC110/220V to DC48v 10A Switching GaN Power Supply for TPA3255 Stereo Audio Amplifier

Review: Transforms the amp – worth every cent - ⭐️⭐️⭐️⭐️⭐️ This 48V / 10A GaN power supply is an absolute game changer. I’m using it with a Fosi V3 in my home office, driving B&W DM603 S3 floorstanding speakers, and the difference compared to the stock PSU is not subtle. With this power supply, the amp gains noticeably more headroom, control, and authority, especially in the bass. Bass is tighter and more confident, dynamics improve, and the overall presentation sounds more effortless. The amp feels far less constrained at moderate listening levels, and transients come through cleaner and with better impact. Build quality is excellent — compact, well-finished, and it runs cool thanks to the GaN design. No noise, no coil whine, no instability. It’s been completely reliable in daily use. If you’re running a Fosi (or similar compact Class D amp) and wondering whether the higher-voltage PSU is worth it — it absolutely is. This power supply lets the amplifier perform at its full potential. Highly recommended upgrade.
Review: Best clean/neutral power for A07 Max - 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.

### ⭐⭐⭐⭐⭐ Strong and quiet bricks. DGM
*by D***K on January 5, 2026*

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.
