Agree with Psacanli - I'd add that jitter is one of the culprits - so clean power helps as does gear that is low jitter.
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?
