Column
Dual TPA3255 Class D Amplifier
Straight-Through Airflow
The tower form factor exists for one reason: thermal management without compromise. Air enters at the base, flows straight up through the PSU and amplifier boards, and exits through the top vents.
No bends. No dead spots. No recirculation. The same principle that cools server racks, applied to a stereo amplifier.
If the fan fails, convection takes over — heat rises naturally through the same vertical path. The amplifier dereates gracefully instead of shutting down.
The Numbers
Conservative measurements. Not datasheet maximums.

Power vs. Distortion
The flat region is the story — distortion stays imperceptible across the entire usable range.
What The Watts Mean
Most listening happens where distortion is unmeasurable.
Based on 88 dB sensitivity speaker at 3 m listening distance.
