Expert Audio Engineering Commentary

Headroom Notes

Recorded at the 32 V / 5 A supply that ships in the box. Douk's table for the M1 MAX is word-for-word the table printed for the H7PRO, the T6PRO and the ST-01 PLUS - the same four supply rows, the same twelve wattages. It is one TPA3255 board in four cases, and the published power depends on the adapter, not on the model name.

What the datasheet actually says

Quoted verbatim from the manufacturer’s own page, with the date we checked it. We state what is printed, not what anyone intended by it.

The maker’s own documents disagree
«max output power reaches 300W per channel — Power output table of M1 MAX: 32V/5A 8Ω 65W+65W; 36V/6A 8Ω 94W+94W; 48V/5A 8Ω 102W+102W; 48V/10A 8Ω 185W+185W»

The 300 W claim in the description has no row in the manufacturer's own table; against 8 ohms the table tops out at 185 W and starts at 65 W with the adapter that is actually supplied. The spread between the first and last rows of the table is a factor of 2.8 for the same amplifier.
