Class D

EPDR, what ever...

Some time back I asked for the opportunity (I also paid for it!) to test an amp that uses less idle power than my Pass X350.5.
~450 watt in my case, standby = 5 watt though!

So here came a pair of Mola Mola monos, claimed by someone experts - being the 'Rolls Roys' of class D amps. 

Well, so why not? 

Long story short, whether it was an EPDR issue or what else ever, they just didn't 'cut it'. 
Why?

Clean as a fiddle they'd sounded, they just could not match the authority of my class A / A/B Pass.
This into a 89dB, 4ohm, quoted Burmester 961, ~35 kg/speaker. 
8“ bass drivers, but by no means a current guzzling monster speakers. 

Anyone think I'd try some more Class D 'Rolls Roys'... not very likely as I feel at present. 

Just sharing for what it's worth... 😏

Well, not that I’m aware of what you suggest, as his review speaker were SIBELIUS of 87 dB.
Those Mola Mola monos are supposed to ’do’ some 400 odd watt/channel (into 4 ohm...) - somewhat more than my X350.5 Pass.
So - no go with my power saving notions.
This issue is/was some often mentioned with class D amps, and can strip music of its musicality. 
Was happy to go back to my present set up.
