I have done so with some items - including the Philips recorder I've
used for some years. However I simply sent the sony back and got rid of
it. Used 'dedsheet' from Wilmslow. This works OK for low levels of case
vibration, but of little use if there is a noisy fan or disc. Thus it
would have been a waste of time for the Sony.


Car paint suppliers usually sell self adhesive pads used for damping
vibration on body panels that have been replaced. Might be a cheaper and
more convenient source than Wilmslow.

One wonders what is going through his mind when he posts this sort of
thing to a UK newsgroup - unless he gets and reads UK audio
magazines...??


(Homeopathy...??)


It's actually a fair enough comical description of much magazine stuff -
if you have any sort of engineering background or understanding. Those who
don't feel the need to invent terms for things they *think* they hear and
they know many of their readers will want to read. And you've certainly
found their source of fairy dust. ;-)

Been known to read UK audio magazines, along with the idea that some UK
audiophiles just might be cosmopolitan enough to read ragazines from other
countries including the US and Germany.

What's your question?

Does 'been known to' equate to 'gets and reads' then..??

I have several - some simple:

Is it ever going to stop raining? (I have a cleaning time/riding time
ratio on my glittery new 'bike of 2:1 atm....)

Is there life after death?

....and some quite complex:

Do I possibly prefer the Technics deck on the Technics amp to the Lenco
on the 300Bs right now, when I can barely tell them apart when listening
from the next room (and forget which is playing after only a single
track)..??

Why is Plowie such a tit?

As well as a few 'themed' questions for the 'You canna beat the Laws of
Physics' yappers he

How big is the universe?

Where does it end?

What's on the other side?

When did the universe begin?

What was there before it?

Where did it come from?

When will it end?

What will remain when it does end?

Why bother with it at all?

??

You know the kinda thing....

It is also the case that some journalists/writers/reviewers write for both
US and UK consumer magazine. I know of current examples in both
'directions'. My impression is that similar types of material appear both
sides of the pond, although for obvious reasons the kit reviewed can vary.

Slainte,

Jim
