Good intentions, I wish you to come to a correct choice (by the way,
it would be interesting to try your D-sonic momoblocks
in case you wish to sell them).
My journey to class D is not yet so extensive, in fact it it remains at an initial step - a light journey to Class D via class A, a non-expensive experiment that i made I have tried to replace PS Audio Gain Cell ($1700) pre/DAC with a Nuprime PHA-9 ($650)
as a pre for PS Audio power Stellar S300, with a quite positive result. The Nuprime has surpassed my expectations
(also taking into account its price): instead of a wax clinic sound
now Stellar gives a live open well balanced sound that
is already pleasing for audition - an essential difference for me, from non-pleasing to a pleasing sound. HPA-9 is class A, it gets hot and the hotter it gets the better it sounds - no way, this is how class A works. Supposedly, it is designed to give a tube-like sound, which, i think, is achieved. It turns our that the cosmetics may change the face -- something that i did not expect. Perhaps, some tube pre would even do better, but i am not currently interested in this, as a good value Nuprime has already emerged. I feel now safer and becoming convinced that class D may attain what i wish.
My goal though is to stay in class D -- not yet clear if it is possible. We need to find a class D pre that does the job correctly, without any cosmetics, and then see if a power class D amp will give a desired result.
To this end, I soon expect to receive a Cherry MEGAschino class D power amp and a Cherry DAC with a volume control. It is a demo MEGAschino (DAC is also demo) unit sold for $3900, $2200 below its retail price. You may wish to hold on, I will let you know about my impressions on Cherry amp in a near future.
According to what i read, MEGAschino is comparable with the best class A amps (@matias do you know how MEGAschino compares with your class D Apollon NC800SL?). I feel it should be close to the reality, i will keep you posted.
Cheers
