In Reply to: RE: The foil is great below 500 hz in my system posted by Awe-d-o-file on March 30, 2014 at 13:36:41
the aforementioned Mr. Sommovigo said that the foil is not optimum and gave me a couple of lengths of the tubular copper wire and it was much better.
Beware of typical masking tape - it will get hard and lose contact with the foil and then you have oxidation. I have cables made with 3M Blue that are over fiver years old and still flexible and fully in contact with the foil.
I had attempted making interconnects by splitting the foil and did not find it to work as well as I hoped it would.
Of course, all credit for the foil idea goes to Allen Wright. I had used his silver foils for years but slowly (and surely) tired of the silver sound.
I like the wire that VDHAudio is selling. It is not getting on my nerves, yet. AS with all in audio, it will eventually. It is a convention round wire with an unusual jacket. Easy to use ...

You have my sympathy... Really. Over the years I've had plenty of things get on my nerves too but have been largely free of such for many years now and it is good. I'm free to listen to the music without fretting about the system. I know it sounds trite, but there you have it.
I'm still fascinated with home audio, but I appreciate being satisfied (enough) with my system that I don't have the urge to thrash it. On the other hand playing with systems can be fun and is (IMHO) a valid pastime in it's own right.
In my experience time-domain problems are usually the root of mysterious dissatisfactions. Things that bother you despite the fact that your system seems to sound good. And they can occur all over the place: in components, cables, speakers even rooms. Naturally they all show up in the frequency domain also but typically not very clearly unless you know in advance what the problem is then look for the spectral artifacts of it. My understanding is that our ears have essentially special circuits to sort out transients, like twig snaps in the jungle, that have a high survival value. If those get accidently activated listening to music then satisfaction is hard to come by.
You need to control near-field defractions from your speakers (and their immediate environment), electrical reflections on your cables, input bandwidth in your amplifiers and dielectric absorption in the electronics.
Piece of cake...
If you happen to have a reasonably fast scope, ie > 10MHz and function generator (or even just build a little prop-delay oscillator from a TTL gate), you can sort out what your stuff is doing in time. I will be surprised if you don't find it helpful.
I love our hobby, it seems so simple but...

A lot of the early pioneers traveling west in covered wagons got a little sick of all the traveling and decided to cash their chips in and stay in Indiana, Missouri or Kansas or wherever. Not that there's anything wrong with that. ;-)
Thanks for the follow up.
