Many way to improve your set up

Is there anyone who has never asked him or herself, “How would my system behave with better electronics?”
Music Hall CD 25.2 digital transport, Sound Fusion Cd player shelves dedicated.
Further adjustment was not needed in the first hours after the system had been properly set up. All the same we placed the transport on a shelf made by Marlen Mogilever, director of R & D for Sound Fusion, a division of the Global Wood group.
This shelf is made up of two modules, the first of 2.7 cm (1 1/8″) plywood, with four brass and plastic cones set into the underside to provide coupling to ground. These four points rest on four Reference Vibe Booster I damping cups.
These damping cups are made of two different materials.
The centre is hard, to receive the point, and the periphery is soft, to provide damping.
A second shelf, made of acrylic 2 cm (3/4″) thick, sits on the wooden shelf, decoupled from it by four Reference Sound Booster III rubber pucks calibrated to accept the weight of a CD player.
The whole thing is a sort of monument dedicated to digital and is unpretentiously called a doublelevel CD platform.
The difference we mentioned? A real improvement in two frequency ranges, the bass and the upper midrange.
The bass had new extension and firmness, voices were better defined and more natural.
The difference was flagrant as we went from one system to the other and back again.
The sound was less dry, smoother, and I loved the midrange, very natural with a nice height.
I’ve noticed in the past that missing detail seems to be the first thing we perceive in a comparative listening session.
For me anyway, going from a highperformance system to one a little less good is more revealing than going the other way.
I can evaluate an improvement and not just a difference.
The extreme highs were slightly laid back, but this is being finicky.
Auditory memory being what it is, I am still thinking of our usual system as a reference.
We thought of trying something just to see what happened.
As we saw, the special shelves under the CD transport were in decoupling (soft) mode.
My idea: switch to coupled (hard) mode.
To do this, I removed the acrylic shelf and the four Sound Booster IIIs, then replaced the four Vibe Booster I cups with four aluminumandwood cups from our catalogue.
This setup put the bass and the lower mids on a muchneeded diet, which allowed the extreme highs to appear where they had been absent previously.
You read us right: decoupling supports under a CD player may well produce a rounder sound. a useful thing to know if that’s what you want.
To confirm our impression, we decided to test Mr. Mogilever’s shelf a little further by doing something he suggests: setting a Vibe Buster II or vibration hunter on top of the transport.
In fact we did get the best results with the Vibe Buster II on top of the CD transport, but without the Sound Fusion cups which cancelled some of the Vibe Busters’ effect.
Set up coupled/decoupled in this way, the CD player sounded more at ease.
The four points + wood shelf + four rubber decouplers + acrylic shelf + Vibe buster Sound Fusion on top of the CD transport.
Simply removing the Vibe Busters from this setup changed the bass response.
Keeping them or not was a question of taste. Some will like their full, ample low end and others will prefer a tighter bass with more slam, better defined and “cleaner”.
Whichever way you like it, the effect is there.
