Very cool idea with a built in pneumatical (?) vibroisolation! I run a small company offering pneumatic isolation platforms for audio. I attempted totalk to various equipment manufacturers about building in such solutions into their products.Unfortun...

[quote user="Paul S"]Regarding the EMT arm bearings going bad in a couple of years from normal use, WTF? That's absurd! Is it a 997? There has to be a better explanation![/quote]Me shocked too! The arm is 929. According to the tech, he has to chan...

Paul, my system is back to the operational mode after the EMT tonearm disaster. Actually the biggest disaster was not the lost connection in one of the pins but....the bearing gave up according to my EMT tech (!!!) I must say I've never heard of a to...

That's ok, I took it with humbleness-I've applied to much force without thinking. I'll use this occasion to change the EMT arm connector to normal 5din to have flexibility with phonocables. ...

|
Paul, I've taken the pains to redo all the connections I could. Washing Deoxit away was a horror. I polished everything I could polish with a jewellery green polishing paste on a polishing cloth, and flushed the remainings with isopropanol.I then use...

Mind you that PP has even-order cancellation only in the ideal world. The imbalances in the PP pair, either random or intentional, will generate some even harmonics. I think Lynn Olson was using an intentional imbalance in his Karm amp exactly for t...

Today I connected a vacuum cleaner to my dedicated lines to burn them in and I immediately noticed its smoother, quieter operation with increased sucction power!.....:D......Sorry, couldnt resist :DTo the boutiques: Paul thank you, I've known all tho...

All polished with Flitz, cleaned and greased. I definitely have to establish a safe regimen for draining the caps in my amps, however; I won't risk death to change those IECs! ;>

You want to tell me that you use pure copper power outlets too? ...
|

...as you are making me dis-ass-emble and clean every-freaking-thing from the cartridge pins down to the power distribution box and fuses where I used deoxit too.But i accept the challenge, lets see where it brings me. Got your point on pure copper p...

What kind of di-el grease do you use? Silicone based? Could you give the name please.Also what was your procedure: steel brush -> grease -> reconnect? Yes, I use Vampire RCA for phono, unofortunately the golden layer is not very durable, on one...

Those crazy braidings I posted were a bit of a joke;) I'm a bit uneasy with using bare copper (oxidation) so would rather go with plated (Ag to have less potential difference to nickel in my sockets). I used Deoxit throughout all my dedicated power l...

I found some crazy braidings techniques, no idea what they are worth. I put it here FYI: http://www.freepatentsonline.com/6242689.pdf ...

Thank you Paul! Very clever idea with the noise drain wire (I saw it also in of the Belden cables, 19634)Unfortunately in my case I have to ground via the power cord (no chance for a dedicated ground).Tried to locate Ohno Cu plugs to no result, will ...

[quote user="Romy the Cat"] When I trying to catch what cord would be the best I do not go for “best
sound” but rather for “steady sound”. What I discovered that the cord that do
spectacular do not do well all time but rather cords that do just OK ...

|
[quote user="Paul S"]fiogf49gjkf0dWe do have a cable thread somewhere on this site that might be better for cable-specific posts. As far as purely electrical "issues", in the end, better sound is still the main consideration. Shielding power lines i...

Paul, thank you for your explanations. No idea if PCC is alkaline but according to its manufacturer it has some isoalkanes and isopropyl. Visually it does remove it quickly (also my Cardas solder is not leaving much of a flux): http://www.kontaktchem...

I've noticed recently that I'm constanty driftting towards baroque and early music.Here is my latest discovery (appologies to the experts): Le Poeme Harmonique.Say magnifique is not to say anything! Some samples:A. Boesset https://www.youtube.com/wat...

Paul, thank you. Sure thing: I first solder, than clean mecanically and/or with a special solution for cleaning PCB's (KONTAKT PCC), let it dry and then apply shellac.I dont use water after all that. I may also apply to thick a layer. Isopropyl evapo...

[quote user="Paul S"]fiogf49gjkf0dOver time I have observed that, in most cases, one quickly turns the corner from "enough' connector mass to suddenly arrive at "too much" connector mass. I started out with a cable clamp like Jessie shows for my 6 g...

it's more similar to removing say some delicate wool from your ears. I guess some recordings benefited from a bit of the veil but then its a problem of the recording.[quote user="Paul S"]also the Big Problem that the listener's tastes are required to...

[quote user="Romy the Cat"]fiogf49gjkf0d1) 3) The common mode filter you have at the PS’s input- why do you use them? They do eat some dynamics. As many time I removed them from all imaginary components as many time I witnessed better sound. ...

For some reason I've remembered this old idea of Romy and decided to check itfrom the physics point of view. Unfortunately it seems it will not work:the momet of intertia of a fluid in a vessel is with a resonable accuracy zero with respect to the fl...

Ok, quite impressive measures, I also once had an idea of sandwitched cabinet construction. Hope it will work. 4mm steel is quite rigid but weights a lot. If $$$ permits you may consider copper for the inner layer instead of alu to create a good ele...

Anthony, have you tried powering this all up (with dummy loads) to see if the outer steel skin will not sing? 20mm is nothing for LF magnetic induction.Best luck,N-set...

I should perhaps give it more thought as I thought that instruments do not go higher than some 5-6kHz in their vibrational modes.Here are for example beautifull laser holography pictures and spectra of vibrating cymbals :) http://www.lutins.co.uk/cy...
