Since this is apparently promotion and discussion of a commercial amplifier, I have moved this thread to the appropriate area. The OP and person selling amplifiers, Federmann, will keep all of his future promotions and discussion to this thread.

Example specifications
Clearly wrong. With +/-50V, you cannot get 1000W in 4 ohms. With +/-60V you cannot get 800W in 8 ohms.
Makes me wonder how real the other numbers are.

Really? So how can the average then be 100W in 4 ohms and the max 1000W in 4 ohms? What's the difference between the 300W and the 1000W number? How did you measure it?
Same questions for 8 ohms, please.

300W and dynamic headroom 5dB = 1000W
100W and dynamic headroom 10dB = 1000W

Upupa means so called Federwatts
Like you could see one post above - "300W and dynamic headroom 5dB = 1000W".
