So 2.4.4 does have fewer clicks and pops but some still remain.
They weren't a 'problem' for me but some were afraid for their tweeters.


I can't hear any SQ differences between 2.4.3 and 2.4.4

It's a factory upgraded MKI to MkII unit.

And as for a direct comparison of the micro detail I can't really say.

My HD800 system has much more inner detail and small signal dynamics than the speaker system I heard.  And until I get a chance to do and A-B using my system it would be 'premature' to speculate.

But having said that, the signature of the C3 (as I call Cohesion, Coherence, Coupling) was there, which tends to suggest that the small signal dynamics et al. are at least at the same level as a (slightly) tweaked PWDII.

And after seeing the boards and understanding the circuit topology and it's simplicity, such as there is no active output amplification, etc. I would surmise it should provide better SSD, and better C3.  Which when added together can result in an improvement of what I call the Spooky/Scary (magical is another term that applies) listening experience.

That the S/S was also evident, although not to the same degree, suggests to me that the DS should surpass the PWD in these and all related areas of sonic wonderfulness.

I would like to add these pics for any future reference if it happens to help anyone.  They are telling about the differences in the PWD1 versions of the analog board which may or may not impact this "mystery."

In this particular mk1 it had the type B analog board installed by default and I swapped in the A board along with the mk2 digital board.

Sorry for the craptacular picture quality - I was in somewhat of a hurry.

Here you can see the mk1 top vs mk2 bottom digital boards


Here you can see the two different analog boards version B left and version A right


Here's board B alone


Here's board A alone


They appear largely the same except the placement of the cables that would connect the analog board to the digital board and the in/out connectors are slightly different.  Why PS Audio would end up doing this is beyond me even from a cost perspective.

Please report back!
