OK,
My latest foray into hifi has been to build an isolation platform. The idea is to reduce vibration both vertical, horizontal and rotational.
Its not flashy, it doesn't have WAF (to be honest, its not that bad), but it works.
After a suggestion from another forum member, I have followed the Bob Diament idea and ended up with:
Hifi shelf > 12" inner tube slightly inflated (£2.50 ebay) > granite plinth (£9.99 sainsbury) > tablespoons (3 of, not stainless steel, with handles bent off, attached with blue tack) (£0.00 kitchen)> 3/8 inch ball bearings (£5.00 ebay) > metal base of cd player.
The ball bearings are placed into the spoons and held in place by gravity. Soup spoons would be the most ideal due to the circular curvature but I had none to hand so used ordinary spoons.
As for the spoons, non-stainless steel ones are better as the handles can be bent off easily (I have minimal tools at home). I did try coaster cups from Homebase but they were too free running and the cd player may have fallen off the shelf. I used a large blob of blue tack below the spoons to hold them in place on the plinth.
A straw tube is recommended under the inner tube to let air in and out of the cavity produced within the inner tube when granite plinth is on top and glass shelf is blow. I used a disused pen as it is unlikely to collapse under pressure, unlike a straw.
I have to say that my cd sounds fantastic. More accurate bass, larger soundstage, more pinpoint imaging, accurate treble. It is nearly the system that I have in my head. The only current drawback is having to warn friends not to press the buttons too hard when they change the cd.
If you want to try this, and to get a more accurate description of how to build this, use your search engine and search for: cd isolation platform bicycle inner tube
Good luck!
PS I have also placed a plinth and inner tube under my technics 1210, resulting in a better sound.
