A revealing, resolving system is superior, however all it takes is one sibilant component or cable to skew the balance and make it harsh sounding. It is possible to have your cake and eat it too, but not inexpensively.
One can certainly add tubes or cables with roll-off to deal with this, but ultimately you are going down the garden path, not improving the overall system.
The best thing is to identify the offending component or cable and replace it.
Typical offenders are active preamps that are too cheap. I have found that active preamps under the $10K mark, particularly solid-state are usually poor and add the most sibilance and compression to systems. This is why I use either a transformer passive linestage or the volume control in my DAC, which is not like a preamp.
