Can good speakers take edge off digital?


I have a pair of Quad 12L2 speakers hooked up to an 845 SET. When I am listening to analog, the system sounds fine. But with digital, well, it has that bit of the digital edginess. Can a better pair of speakers, say the Zu Druid, take the edge off the digital?

Interconnects & AC cords. Line conditioning. Shelving & footers. Fix the CD source: tweak or upgrade it. The rig sounds good otherwise, so don't mess with it.

I am using Monarchy NM24 tube DAC and Marantz SA-15S1 SACD player.
I have a monarchy nm24 as well, no edginess when using it with my powered monitors or my devores. I use a computer source. I am sure you know that the monarchy DAC's tube outputs are the lower connectors - the SS output is much "crisper" than the tube output.
Do you still have the edginess if you take the DAC out of the chain and use the Marantz only as the source? If so, the DAC may be the culprit, but if not you should probably look at the speakers, amp or cabling.
Better speakers, more transparency, the more digital flaws will be revealed. Good digital is a must or you will be begging for some digital band-aid....Analog is needed just to know a good reference for music.
