Can good speakers take edge off digital?

Agreed with some of the other posters. Good Speakers (Vandersteen 3a Sigs) forced me back to vinyl after 25 years. (I still listen to CDs and SACDs)

A good DAC will take the edge off, I use a benchmark, there are plenty of others but that did the trick for me. Not only did the edge mellow but the mids and lows cleaned up and extended, benefits from top to bottom.

One problem is most loudspeakers cheap out on the tweeter. Toss in system mismatch, poor dac etc and you get harsh edgy sound. Tweeters are hard to build right and the ones that do sound good are costly.

Digital will alwas sound digital to some extent. vandersteens mentioned above are very smooth and netural even laid back speakers and do help alot, I have had several and they are my favorite brand for the price. Something brigher will sound more digital. So yes speakers can help, but as stated above I think other things cause it as well like the source and wires. What are you running for a amp and pre amp? I found when I went to tube amps and pre amp it smoothed everything out. I also run a cary 303 cd player that has a tube stage, you can turn it off swap out the tubes, upsample so I have alot of choices how the sound comes out. Generaly I don't like Cary but this they did a good job on.

No.
To take the edge off your digital use ac "conditioning" and "isolation" on your pre and your digital source.
Very much of the improvement in digital is due to ever more refined power supply.
