Yes, I got those too. It'll be interesting to hear whether the bonded copper layer plays differently from the inserts in my version. Of course, we'll have to contend with both the copper and weight being different, but I can't wait to compare them.
Can I just confirm, Marco, that your Achromat is the 5mm not the 3mm version? The Funk Firm website doesn't appear to accept direct orders so how did you purchase yours?
I'd expect it to having thought about it :) Copper is softer than alloy so it should have a damping effect on the alloy platter, with it being bonded this should be quite a bit better than just sat on top. From what i can remember copper even if shaped the same way as alloy rings far less & at a lower frequency as it's heavier than aluminium, not sure about the alloy used in this platter though :scratch:
The idea is fundamentally sound :eyebrows: Excuse the pun ;)
Hi Martin,
Yes, I can't wait to compare the platters, too......
I'm not sure what thickness of Achromat Arthur sent (I don't have it in front of me at the moment to measure, and I'm just having my dinner) but he would know, so best just to email him and ask him.
You can order the Achromat at the same time :)

There are some exciting times ahead, as I have a feeling this new platter (in conjunction with the Achromat) is going to raise the performance of the Techie to previously unprecedented levels!
Marco.
Apologies, I was half asleep when I typed this. what I meant is that your composite platter has been tested on a techie before you receive it, so you won't have the supposed problems with ill-fitting as alluded to elsewhere.
I hope this works out OK for all. I hate it when other, subjectivism aligned sites make gleeful entertainment out of threads like this, even though the targets aren't really the mass-membership. Some people can be so cruel and it rubs off on those of us here who post with the utmost civility.
Ah, gotcha now, Dave :)
With regard to the other thing, we're so far above those shit-filled cesspits, we simply look down and spit on them with the contempt they deserve ;)
Rising above it (and them) is the best option.
Marco.
The new platter which Marco has posted a pic of, is essentially the same unit with a
3mm thick annealed copper plate bonded to the alluminium surface. The copper plate is not removable as it is pressure bonded to the platter body. The copper plate is annealed at 600deg C before being quenched in a Sulphuric Acid pickling bath. This has the effect of rendering the copper pliable and more resonance absorbent, (it also etches the copper ready for bonding) and allowing a very close allover bonding connection with the top surface.
This is, I believe a superior alternative to a free floating copper mat, which cannot have the required connectivity to the platter body as such. Although I have in posts elsewhere, recommended that people using these, should use a coating of good quality silicon grease (or Vaselene) in order to improve things.
The MN platter I have is 2mm thicker than std and has the contouring for the bearing and stiffener. I use the 5mm funkfirm achromat, and the combination sounds heavenly.
I am curious and look forward to your results Marco
Cheers
Pete
Would there be anything wrong with highly polishing the copper and placing the record directly
on it and making a mat optional ?
