I am assuming that the CNC casework is the same for all Klimax products with just the rear panel being the product specific part. There are certainly additional PCB mounting bushes the the photo you referenced. (see below)

Not yet. I just haven't had the time or the energy right now. I'm going to strip it all down sometime soon (further ideas) so I'll try it then.

TBH as removing the top won't allow me to use my grounded top plate (thereby loosing maybe 3-4kg mass) I don't know what will; happen.

Thanks mate. Its been an interesting journey, well start of a journey anyway.

Once I have finished all of my ideas (well, finished the ones I have in mind right now. No doubt there will be more to do as soon as I think I am 'finished' :roll: ) I will do a re write. Lets hope I remember what mod did what.

Tried it with the lid off.

Quick Précis:- More HiFi less Music. Bass overblown and woolly, treble harsh, not nice at all.

OK, after the "topless" experiment, back to todays main event. After talking with David W @ LINN I wondered about the feet and coupling. The supplied feet are heavy metal, BUT have a rubber/felt pad under them, and have double sided tape at each interface. All of which must give some sort of suspension effect. Would a more rigid set up be better? Well, lets see.

I removed all of the parts fitted thus far and disposed with the internal divider as it was adding little(if anything) to the sound. I drilled a 4mm hole in the bottom plate centre back countersinking it on the inside. The holes where the LINN rear feet would go I countersunk on the outside.

I already had a set of Russ Andrews Jumbo Cones lying around, so I put them to good use. Using a thread reducer (the Oak Cones have a M6 thread, and the Radikal case has M4) I fitted one oak cone centre back, then bolted the bottom plate in place with 2x M4 bolts from the LINN feet at the rear, and used M4 studding to hold the front Oak Cones in place at the front.

Back in the rack, top plate in place and grounded as before.

Result? PHEW! The music is back again. Nice and precise (Mrs O's very words) Bass is back under control, soundstage a wee bit wider and all together more musical.

If you are doing the base plate, then I recommend you do the feet as well.

James,
Did you use a earth strap and mat every time you opened your Radikal box?

I have a very low static charge and always earth myself before opening any electronics. I have never needed an earth strap even when fitting a processor chip to a PC Motherboard.

Mrs O is another matter, I never let her in the room when I am electronicing.
