Anyone here tried Elco Cables

I guess that I should tell you about my system, it consists of Sim Audio P-5 Preamp W-5 Amp Vienna acoustics Bethoven
Speakers with a Metronome tube cd player. current cables are analysis plus all copper, I am quite happy with it as is but was going to try silver cables to compare and have heard good things about Elco Audio cables.

I own the Elco GL999R .
Which is there gold version.(purchased this last February)
It has very good midrange and Female vocals are outstanding.
I notice the bass is a little weak on my CD player(Meridian 508.24) but better with other source material, so I guess it is system dependant.
I believe the gold will take a long time to break in, so maybe that will change.

For what its worth, the Elco GL999R gold Discription and the Stealth PGS look and the discriptions appears to be identical.
I can't comment on the Silver

I'm using the Elco digital cable (the nicer model) and it sounds pretty great. I've compared it directly to the Cardas Lightning 15 and Acoustic Zen MC2. The Acoustic Zen is a little more laid back sounding than the others, but the Elco has just as much detail...maybe more. I'm not done choosing yet, but I think the Cardas may come in 3rd. They're all a little different as far as detail, soundstage, and tonality, so it can be hard to choose which I prefer...it depends on the recording, my mood, etc. All the rambling aside...the Elco is a great cable, but it's $650 retail price is ridiculously high (though, based on what I've seen, it doesn't seem like they stick to those prices too often).
