Kill Top End Extension - All Silver Ribbon Cables

Hi Guys,

I have a system were ALL the Interconnects and Speaker cables are all Pure Silver Based Ribbons from PSC Audio. http://www.pscaudio.com/ Would any of you know, whether this would be a BAD idea, if my current system is a tube based setup. I guess I'm wondering if this whats killing the top end extension in the music. ie. the nice shimmer on the cymbals. I've changed all the tubes on the pre-amp and the Amp is only about 2 weeks old. Furthermore, the pencil valves on the CD player have also just been replaced.

System Configuration
Amp: 13E1 Tube Monoblocks
Pre-Amp - Supratek Sauvignon
CD Player - Audio Aero Capitole MKII
Interconnect: CD to Pre - PSC Custom Pure Silver Ribbons (1 mtr)
Interconnect: Pre to Power PSC Custom Pure Silver Ribbons (2 mtr)
Speaker Cables: PSC Custom Pure Silver Ribbons (2 Mtrs)

Many Thanks to all that reply...

By increasing the spacing between the positive and negative runs of a speaker cable further apart from each other, you increase inductance. Inductance in a speaker cable kills treble response.

If you want to keep the cabling that you have, try taking the two runs and spiral wrap them together. Due to the spacing between conductors that will still exist, you're still going to be on the inductive side, but this might help a bit. You'll probably have to replace these cables to solve at least a good portion of the problem. Sean

In addition to all the foregoing comments, it seems to me that silver (and silver alloy) cabling tends to accentuate the high frequencies. So if anything, your cables are adding to the HF extension, not detracting from it. Must be something else.

Essentially, it sounds like you have new (or newly replaced) tubes throughout your system. Give them a 35 hour week of regular daily play (that means at least 5 hours a day) and if beginning the second week, things don't start to sparkle, then it's tube rolling time!

I just went through the same thing. The interconnects were not the problem but the speaker cables caused a roll off at the top. My VAC PA100 did not have any problem with the silver ribbon (Audio Magic brand) speaker cables but the VAC PHI 110 did not match well at all with these cables. I replaced them with a hybrid silver and copper MAS Reference speaker cable which is a non ribbon design low inductance cable. That solved the high frequency roll off problem for me.

Your new amp needs to break in. If the transformers are new, you should not really expect any magic for a few hundred hours. That's a lot of wire to break in, plus all the caps. I'll bet if you just wait it out, you will be pleased. I can't imagine your silver ribbons REDUCING the high end. It sounds like typical "new amp" syndrome.
