Hello Ptss. What is musically rewarding is subjective and will be different from person to person.
The Revels will play louder without strain and do have a fuller bottom end. If this is important to you, have a very large room, and if the the majority of the music you enjoy would benefit from these attributes you may very well find this speaker to more musically rewarding.
The Eidolon Diamond with the right associated equipment and set up properly can sonically disappear in a room in a way the Salon simply can't. For me at times they can sound scary scary real! They're more coherent, nuanced, and yes, resolving of 'real' instrumental detail. After living with these speakers for as long as I have, I now find most other speakers to sound disjointed.
best,
Tom
