I would just mention again ( see my past postings) that adding a clock will not produce some kind of knock you over change as if you pressed a button marked “bass enhancement” or " vocal exciter". It is subtle but ultimately profound. It just makes everything increasingly natural.
I guess this depends upon what kind of listener you are.
For me, if I shut off the clock, the entire sense of space in a performance becomes nebulous at best. Sinatra is singing in a studio, but how big is that studio? Do you hear echo from the walls? It’s nice, but, not that exciting.
Turn on the clock and the walls come back. Piano notes lose their hard transients that made them sound more metallic than felt hitting a string.
I’ve mentioned before that the Rossini without a clock was not as good as my Wadia S7i and I never would have purchased one.
A Rossini with the Rossini Clock finally exceeded the Wadia, which is why I made the change.
Meanwhile I’m still blown away by what a change clock cables can make; they shouldn’t affect “sound quality” but wow, do they ever.
