I currently have my LP12 on a Solidsteel wall shelf. The wall is plasterboard but I have added a 50mm piece of timber between the studs and to a depth of 400mm. All sounds good.
my wife is not a fan of the shelf and would like it removed with my LP12 moved on top of the unit where I have my streamer, phono stage and power amp.
Does anyone have any experience of turntable isolation platforms for mounting on top of a media unit that will isolate vibration. My turntable is still subject to some vibration on the wall shelf, which is greater than I can feel through the media unit.
Not much advice except try things and see how they sound. I think the main problem will be coupling the LP12 to something that has high mass like a sideboard. As the Sound Organisation proved, way back in the 80’s, low mass tables are the way to go. I’d try something like the Mana tables, the small base ones not the big ones. A couple might be good with the board on the bottom and glass on the next one. It’ll be a trial and error thing but at least you have a good baseline to compare it with. If you have Linn’s suspension base board it would help but if you are using standard rubber feet the LP12 will be very sensitive to placement.
So much depends on the media unit. Can you move the shelf so that it hovers just above the unit? Are there other compromises that can be reached? Maybe post a picture so we can give you some ideas.
This is my system at the moment. I’m trying to remember exactly how much timber I installed behind the plasterboard to relocate the shelf to the right and down
That looks very nice indeed, though I see what she means, as the Linn is a bit stuck in the air. I’d move heaven and earth to get it lower, so that it sits just above the unit. I certainly wouldn’t put it on the unit, as it won’t sound anything like as good, no matter what isolation shelf you put it on. Get some Gyproc Easifill to sort the holes, a touch of paint and you’ll never know where it was previously.
Just the plinth, all furniture and racks are custom made by a friend who is a Cabinet Maker.
The Lagom platform is beautifully made and does a superb job of isolating the my wife’s LP12.
Isoacoustics Zazen or similar isolating plinth? They have a few solutions actually. If I was dead set on keeping the turntable, I’d probably look there. Bear in mind the LP12 is already fairly well decoupled; I’d be inclined to try it without anything (provided the cabinet is dead level).
If HH’s excellent suggestion to lower it, so that it hovers just above the cabinet, doesn’t fly with the boss, I suggest a Townshend Seismic Podium.
They are available in various sizes and load ratings, so it’s important to get the correct model for your turntable.
Several forum members use these under their speakers with excellent results. However, they are also available as singles to use with turntables.
Spiers Robinson is a UK manufacturer that makes anti vibration platforms for the labratory industry. They do not cost more than typical hifi equipement, but I believe they make better products.
The air platform with a resonance frequency of 2Hz in 400x500mm size cost ÂŁ1600 ex vat.
