Thanks Paul
Sounds one for me to skip with all the variations I have
Let me know if you want the contact details for the guy I bought my RDCs from, nice and cheap, for RDCs

I was actually thinking I could lend you three of these to evaluate at your end. I would like to know how they perform for you because you have a number of things to compare them to. I would wait until you evaluate before I think about ordering RDC.
These seem to me to be doing a good job. But my equipment is oddball. It would be helpful to know how they measure up in a setup like yours.
I don't care if your evaluation is private or made public, I am only interested in how it sounds to you. the ebay seller hasn't listed any since I bought mine, so maybe the end of a line anyway. Just be noce to know whether it is necessary to look further.
I suppose we have a pm system here to exchange addresses.

Very happy to try them out
I have a clear order of what I think sounds best.
They can slot into that list - Maybe a huge bargain !
PM sent in a sec

Packaged and ready to go.
Glad you have a clear mind on the matter.
I am liking what I am hearing, bit don't have anything else professional to compare them to. Admittedly it is nice for once to have something I didn't have to "Heath Robinson" together.
Bit burned out over the diy. Just taken a back seat and listening to what I have and if it breaks push it aside and listen to something that hasn't broken yet.

Ok Paul kindly sent me his 3 legs www.ebay.co.uk/itm/310820937754?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AITThe results were slightly variable against RDC cones with ties (can't tell them apart), wins for RDC, by the skin of the teeth and a fairly clear result for RDC, still not huge, VFM I'd give it to Paul's at £12 odd for 4 RDC-1s are just under £50 Prices are for 4 I use 3 so buy 3 sets of 4 of either and get a free set ! I'm assuming neither burn in  |

Clearlight RDC (Resonance Deadening Component) Cones
I really must put in a good word again for RDC Cones. I don't know exactly what they're made of, but they're pretty tough and inflexible and so I guess their behaviour veers more towards spikes (conducting vibrations to 'ground') than absorbent footers. The thing about them is the cumulative effect of using them with all system components. Here, there is no such thing as 'too much of a good thing' as they are so neutral, they just seem to let more music through, improve transparency and tighten up the bass. Some of what they achieve seems counter-intuitive, but they really do work. What's more, using them from source component through preamp to power amp just gives you more of that goodness.
They are best used point-down (with some exceptions) to allow their base to make full contact with the underside of the component - not the original feet. I use very thin double-sided tape to hold them in place. You don't want foam tape or anything else interfering with their mode of operation. I use them mostly in threes and distribute them according to weight distribution (for instance, my Ayre SACD player is very left-heavy where all the transformers are, so I have two on the left and one on the right).
My RDC Usage SACD player: RDC1 x 3 Turntable: RDC1 with M6 thread x 4, RDC Cups, RDC Combi Bases on upside-down Techniboots Turntable PSU: RDC5 x 3 Phono preamp: RDC1 x 3 Phono preamp PSU: RDC5 x 3 DAC: RDC5 x 3 Preamp: RDC1 x 3 Preamp PSU: RDC1 x 3 Power amp: RDC1 x 3 Regenerator: RDC3 x 3 System rack: RDC1 with M8 thread x 6

I know! I can't find any English on them and, anyway, I'm happy with the current range.

I'm assuming neither burn in I sent them to someone with other supports to compare them with because I wanted to know how they compared. I have no point of reference over here. On their own without a comparator they made a significant improvement over the four rubber feet equipment is stupidly sent out wearing by ignorant manufacturers. |

Definite VFM, 'bargin' even
The puzzling thing was the variable results I still can't get my head around

What I don't get is that speaker manufacturers test their speakers using the feet provided by them.
Assuming they 'tune' their designs to sound best when set up that way, surely using any other type of support may give you a different sound, but it won't be the one the makers intended you to hear ?

such concepts are never ending but not a reason to give up at home. An improvement at home is still an improvement.

Some manufacturers just make the stuff of course
Modifications can be better or worse. What I have found is these things work on almost anything from anywhere so assume they address a common fault/issue

Listening this morning to the Isis CD player.
More information coming out of King Crimson - Lizard than ever before.
I have a theory...
Putting supports under live kit that is not in use improves the sound of kit being used.
In this case I put RDC cones under the VIDA and Technics outboard PSUs yesterday (yes they improved sound on LPs)
No time to test this morning

The major influence on speakers is the room . A manufacturer can't optimize their speaker for every room size, construction , furnishings , listening position . |

Been listening to CDs I know well over the past few days
There is more information coming out than I knew was there before
I'm wondering if albums I don't rate (as well made) will also respond
Thank you RDC cones

I am finding the same thing, Mike. The RDC Cones are having the same effect as upgrading the Ayre, revealing all manner of things on CDs that I really have 'worn out' over the years.
Last night, just out of interest, I played the Ry Cooder BTYD CD for a change, to hear how it compares with the vinyl (never very well in the past). Well, blow me down - it sounds different but really almost as fab as the vinyl now whereas it was very, very far away before! Not quite as liquid and flowing, but every bit as dynamic and with some very fine detail I don't remember hearing on vinyl.
