Topping LA90D Power Amplifier

The dead silence between tracks is astonishing—this discrete amp pushes my headphones with zero background hiss. It’s easily the most transparent sound I’ve heard from a compact unit.

I wasn’t expecting the discrete NFCA circuit to make this much difference, but the LA90D is dead quiet even with my most sensitive headphones. The staging feels wider and the bass has real weight now — it’s the cleanest I’ve heard my setup sound.

I’ve been swapping amps in and out for years, and this discrete design finally makes my speakers sound like they’re not being held back. The lack of any hiss even at high gain is what sold me, and the bass control is tighter than anything I’ve tried. It’s a real step up from my old class AB unit.
