Ok, as previus thread, my P5 has come under a lot of tweaking attention over the past few weeks, this last week in particular. Some of my work I keep to myself, you may have notised . . . purely becaus of the rather off the wall nature my mind works and the negative reaction it generated, think about it.
However, one area I looked at as an aside initialy . . . 'the Cartridge Man' does a cartridge decoupler, goes against all the well troden pricipals we have been tought over the years, find it here: http://www.thecartridgeman.com/isolator.htm
How much!!! . . . I have looked at it befor, dismissed it as bunkum, never even looked at the price . . . £85, double bunkum! Thought it over a bit more, had an idle morning waiting for a new fridge to be delivered . . . why not? Its about time the cartridge was checked out properly, reballanced and realigned.
So a dig in the scrap box, I design and build RC model aircraft as a hobby too, I came up with the required bits. A piece of beech wood from the TT shelf I built last year, high quality double sided, self adhesive foam pads, I use them normaly for sticking control surface actuation servos in my models and a couple of head shell bolts.

You can see from the pictures, the construction is simple, I have not mentioned the copper mass weight, ignore it, that comes later. The most dificult bit was grinding the bolt heads so that they fitted flush to the Beechwood interface. Drilling and countersinking the wood was delicate too. The bolts are finally superglued in place, its then a simple job of sticking the double sided foam pad to the Beechwood interface, marking a center line and adhearing the cartridge to the foam pad, job done. The assembly is then attached and aligned in the normal way to the headshell.
Looking at 'Cartridg mans' offereing I was confident my version would do the job if the claims and reviews were to be believed. If it does do the job, it throws out of the window all the solid mounting advise we have ever been given?????????
Stylus to record . . . nothing out of the ordinary initialy . . . all that effort for nothing? By the middle of that first track, Hazel had stoped preperig the evening meal and was sitting beside me, we were both spell bound. Musicality had taken over, dynamics, b i g g g g image, extra detail from the backing, vocals were simply awsome in their presence, oh yes and the base line was so tunefull.
In the short session we had on Friday evening, music listening had taken on a totaly new perspective. 'Horlicks hour' followed, neighbour considerate low volume in the early hours had taken on a new 'dynamic', with images half way down the garden, air and detail we just did not know were there before.
Laugh or snear if you will . . . I was certaily sceptical! But proving the point, I aint snearing now, I have a smile from ear to ear.
Copper mass weight? yes thats peculiar to the Audio Mods arm, holds the head shell solid, with mass being added to the counter weight as well, it has a refining affect on the above description.
