On another note...there is one CD I have ( a copy ) that absolutely
drives my drivers (bass) to the point of destruction...a 3/8's to 1/2 inch
throw on a normal CD and with this one specific copy they are going near
one inch....even at very low volume....any ideas?

P S It blew one driver before I figured it out...a not inexpensive
repair...

if it is JUST that one CD, I would simply suggest avoiding it. Otherwise, a
subsonic filter, if your preamp has one, will address the issue if it
happens regularly. Odd that it is a CD, as I've heard that issue from LP
play more often, and that issue can be frequently traced to one of a few
factors, such as tonearm resonances, surface resonances from below the
table, or improper cartridge setup.

I never experienced that problem when I was spinning vinyl...and yeah....it
is just that one particular CD. It's weird as heck. I have a call in for
the original and for a copy to be made on another system to do some
caparison tests...

Now....in case anyone is curious....do I copy CD's? yes. once.
We go halfsies and the winner of the coin toss gets to keep the original
jacket....do I boot leg or buy such? no...


I will let you know the results of my tests and I will take a drive Monday
to go and talk to the most knowledgeable people I know at Parts Express...

they are Arum Cantus speakers, Adcom amp and pre amp....a small not so
powerful system but ideally suited for my listening environment.....

no way should the displacement be that great on those woofers......even 3/4
inch would scare me on my Klipschs, and they have 12 in woofers....At any
rate, the Adcom should have some sort of a bass filter to moderate very low
bass, but it is odd that only the one CD copy gives you an issue. Good luck
on your quest, John.
