In this review, I explore the Ampapa D1 by Douk Audio, a budget-friendly Class D amplifier that is challenging the "commoditisation" of affordable hi-fi. While most TPA3255 based amps look and sound identical, I discovered that the D1 offers a unique, accessible design specifically for op-amp rolling.

I put this unit to the test against the popular Fosi Audio V3 Mono and paired it with both the Starke Beta 5 and ProAc Response D2R speakers. I dive deep into how it sounds stock with the NE5532 versus high-end upgrades like the Sparkos SS3602 and Burson V7 Vivid or V7 Classic. If you’re a fan of hi-fi audio, speaker amps, and audiophile gear, you’ll want to see why this might be the most "fun" amp on the market. I break down the soundstage, imaging, and whether balanced TRS inputs actually make a difference in your listening room.
