What device are you using, are they costly? I want one!

It’s not a competition but quoting the internet (and it’s associated grammar) is not a winning combo. More pertinently, purely stating well established doctrine, does not form a point of view nevermind an argument. Sorry, I’m tired, but if you have no worthwhile technical input to give then don’t kid yourself - Google is not always your friend! If you read what I have written then I am, in general, supportive of that which you have done.

Edit: don’t waste your time waiting for me to reply again.

Well it may sound silly but it is an iPhone accelerometer app. The accelerometers built into modern mobile phones are surprisingly accurate. Maybe not as accurate as a Brüel and Kerr accelerometer and tape recorder but not far off and it does the job.

You can dump the data to a spreadsheet and then put it on a graph and directly compare before and after, amazing what modern tech can do.

I agree, not in any way definitive, but interesting, and relevant, to a degree.

Thank you for your interest and your thoughts.

Indeed. The 'proof of the pudding', and all that...

Mark, I think you're being a little hard on Peter and making the discussion more confrontational than it need be. I understand that you're interested in the design principles of the Pylons and what makes them work, but could you please be a bit gentler about it and less interrogatory?

You yourself admit that the feedback Peter's had has been 100% positive, so what he's designed must be doing something right. Therefore, let's keep it friendly, and when you're drilling down into the details, avoid things becoming unnecessarily argumentative. Cheers:cool:

Marco.

Well said Mr. Moderator. I have an Odyssey deck, ( the picture is posted within this thread, ) amongst others, which now sounds great. I know what I like but if you do not like it then so be it. I listen with my brain and ears and not through anyone else. Well done Peter. The thread was labelled "cheap upgrade.....". Job done. T.

A big thanks to Peter from me for what it’s worth.a special chap and I don’t just mean his pylons.

The Tonearm cable off the sme 309,is held in place with the Michell Clip , or cable tie , take the cable out of it , this is picking up any noise from the TT, the sme cable seems to pick up any vibration near it now ,,and some how support it with a piece of foam ,,to stop it pulling the arm down on one side ,
