I wonder if that correlates to sound too.
Yes it does.... but just for info, the specs I have been able to find on the new Purifi modules are as follow:
Class D amplifier
400W Power for 4Ω
1% THD at 400W
0.00017% THD at 100W
a D400 is 400W for 6Ω
0.00025% THD at full power
0.0001% THD at 10W
So one is just 3 orders of magnitude better than the other when it comes to THD
Jean-Marie
the 3 order of magnitude is dependent how full power is defined. looking at 10W https://6moons.com/wp-content/uploads/au...rifi/1.pdf there is roughly a factor 2 higher than Devialet which is a significant improvement over n-core or other class-D modules. Still sound signature is not simply equated to THD and Devialet is not pure class D so I assume that will have sonic benefits even if the specs would be identical. But for (sub)woofers....
