I’m with you, I much prefer a hinged dust over. I had the high-mass table with separate ginkgo cover for a few years, and ended up listening to less vinyl simply because of all the futzing around with the dust cover, record clamp, ring clamp, etc. Go for the hinged cover.

The only drawback of the hinged dust cover is that it is very prone to picking up all the airborne vibrations like a parachute or an antenna... We can't get around the airborne vibrations part since that is "music" in the air.

Serge....I do agree with this; and for that reason I always remove the dust cover when I'm spinning vinyl. On my HK table, this is very easy. The hinges on the cover have male "tabs" which lift out very easily from the mounts on the plinth.

The dust cover picking up vibrations is an interesting concept; I hadn't thought about that, but I can see it as a possibility. With the combination of a Sota TT and a Gingko platform, I don't expect vibrations to be a problem. They weren't an issue when I had my VPI on top of the Gingko either. Perhaps an isolation platform will provide the freedom to go for whatever table you want and can afford.

It's not a possibility, it is physics. The propagating sound wave (bubble actually) that pushes the air molecules that set your ear drum into vibrational motion is doing exactly that to the raised TT cover. You just can't see it. What effect that has on the TT itself we can guess.. How audible is it? Don't know...

Ok, bad choice of words. When I used "possible," I was thinking that it might depend upon specific setups, or whether or not it was something audible when it happened. I don't think I have the ears to tell, myself. I do know that before the Gingko, I couldn't play records with confidence, or had to tiptoe around to a ridiculous degree out of concern over causing a nasty skip of my tonearm. And it happened often despite my care. Suspended floors aren't a TT's friend.

The various platforms, Ginko being one of them, is great at isolating from floor-borne vibrations. It is between the floor and the TT essentially. The vibration is trapped/absorbed to the best of the platforms ability. Nothing other than the best active platforms designed for scanning microscopes and other high precision instruments can be 100% effective. I simply don’t belive it. But it is often more than good enough.

The lids however are attached to the TT itself and as such, they will pass the micro vibrations right into the TT and that completely bypasses anything under the TT. The vibration will first travel through the TT before it will interact with the platform. Opposite effect and completely useless in this case.

I’m sure the vibrations can be measured but in terms of being audible, no doubt it will manifest itself through a TT/arm/cartridge much more so than any other component we like to isolate. The stylus riding in the micro groove is not a DAC with no moving or sensitive to vibration parts.

My thoughts on turntable dust covers were formed back in the late ‘70s and early ‘80s. I was really into making cassette tapes for friends and myself copying records of the day, mostly rock ‘n roll. Made quite a few RTR tapes for local bars, as well. Quickly learned that lowering the ‘table dustcover after starting the recording process was all too audible as a thump so I started listening more closely. My modest system at the time included Large Advents, Pioneer SX 1980, Sony PS-X6 ‘table with a Shure V15 cartridge and a Yamaha Natural Sound cassette machine, the model number which escapes me but it all made good sounding tapes. Closer listening to the finished recordings informed me of another dustcover foible. It became obvious that the recordings sounded much better with the dustcover open. Closed, the sound became smaller, more closed in, duh. Left the cover open for all further listening/recording and haven’t had a ‘table with an attached cover since. The experience also led to a lifetime of believing little things are worth paying attention to.

Quite possible that vibrations were worse when the dustcover was making full contact across the surface rather than the two tabs in the open position. One never knows with these things that can not be seen nor readily measured by the audiophile other than the ear.
