The reason I need more power is because my devialet Dprem's 500w is actually 350w into 8 ohms (6 ohms is not a conventional figure .. most amps are quoted into 8 ohms)
Now add to that , is the fact that DIRAC applies a -6db cut to the digital signal to stop any digital clipping when correcting.
This further reduces the amp power to an effective 1/4 of 350w..round 90w

Coincidently Vivid speakers all have a nominal impedance of 6 Ohm.

Comparing measurments from different test and perhaps with different methods of conducting the test can be a bit missleading.
I liked this sort of test that they used to use in Swedish Hifi&Music magazine.
The test is with a burst of tones that is supposed to be like playing music. The amp in this test is a Rotel 1080 and the red roof in the cube is the rated power in 8 ohm which I think was 200W for a Rotel 1080.
Theoretical this amp would deliver 200W 8ohm, 400w 4 ohm, 800W 2 ohm and 1600W in 1 ohm if it were perfect but that kind of amp does not exist.
