I want to start seeing the big players in this game start using air bearings and mag lev on both the turntable itself and the tone arm mounts. Also, magnetic drives. Anything to eliminate a mechanical connection. I have yet to dream up a way to eliminate the wires coming out of the tone arm. Getting rid of the cord that connects 2 tin cans so the kids can play "telephone" will surely get rid of some unwanted audible resonance.
I’m not so Worried about those things when conventional tech can be so good. I heard a top of the range AVID turntable fitted with a 12 inch SME V arm at the Bristol Show here in Blighty and it was as clear, dynamic and stable sounding as anything l’ve heard on demonstration.
The mechanical aspect of turntable drive can also be a plus if cleverly designed UNLESS you do go down the road of excessively high mass platters to ensure stability and preservation of transient impact.
The old idler drive wheel decks were actually very good on this score, but have been made even better over years of experimentation by die hard enthusiasts. Then there are even more subtle approaches; check out Roksan and Vertere motor compliance systems.
My Roksan V sounds great, it has some mechanical resonance going on from the motor & belt mainly but I kind of like the mechanical aspect of the sound as it's warm, same goes for the Cartridge & arm, it's my sound, kind of what I was aiming at.
I like the idea of Mag Lev, not too sure they would be able to do it or want to really, but if it worked it may be too quiet if you know what I mean. I picked the componentry for their properties ie my Marantz amp also sounds warm, the Kefs balance this whilst the Tannoys amplify it. The Cd player is just very good at putting out a well balanced sound which is effected by the amplifier (warmed) & balanced again with the speakers. All have their mechanical aspects & all add or equalise the sound. Unwanted resonances are dealt with like the Speaker stand and damping parts of this thread.
That's my take on a Hi Fi system, safisfaction with Your own particular sound. You can't beat that, you end up in the "pit of despair" spending hundreds of pounds trying to eliminate noise for the sake of it (listening to the system & not the music).
