Class D is just Dandy!

Noble,
my speakers are the Zu Audio Omen Def. 100dB, very easy to drive - I am pairing them presently with a tubes SET pumping "only" 24W. 
That review that you mention is for the old monoblocks. The new model is 70W with standard PSU and 100 with the improved PSU. I ordered the best one. 
I'm expecting to get the amplifiers in 3 to 4 weeks. Then I can post a review. 

Hi migueca,

     Okay, 70W on the Zu Omen Defs is plenty of power; almost overkill.  I don't think it's too much since it's such clean, low distortion power  You're virtually guaranteed the amp will never clip and you'll have plenty of reserve power for transients.   I think you're really going to like class D with your Zus and I'm certain there'll be much less heat in your room.
     Sorry for the belated response, I just saw your post.  Have you got the amp yet? I'd like to hear your thoughts on the combo.

Enjoy,
Tim

This link is mainly about the Mola Mola pre/dac, but there are some comments about the Kaluga mono block class D amps.

The Mola Mola Makua and Kaluga have just received an award from AV Tech Media as best high end pre and power amp.

If you need to know any more about the Mola Mola let me know.

UK Mola Mola dealer.

Does anyone have compared the job 225 vs any class d amp? 

Little known factoid.

AES17 brick wall filters allow Class D Amps to report specifications IGNORING all the switching noise above 20KHz!!!! And there is a LOT of noise....
