3 speaker cable options - what to choose?

A top KIA is a LOT better than an entry Benz."

Spot on as always, Schubert.

"Currently I want more details and air between the instruments, and that the sound would be more "alive"."

That's something you should take care of with electronics, not cables.

Electronics will be replaced later this year, not now. This a different scale of budget we're talking about. Currently I want to finalize the SC upgrade."

I don't think I get what you are trying to do. How can you finalize your speaker cable upgrade before you have your new electronics in place?

Jmcgrogan - Yup, that's the spirit, everything's much clearer now - just what I was looking for. thanks for the tip."

He's right. There's a reason some of us are not sure that you are doing the right thing by getting your cables before electronics. I can only speak for myself, but I think its foolish. You can get lucky, but the reality is that the same pair of cables can sound different from one piece of equipment to the next. The Gabriel Gold Revelations that you tried with your current amp may sound bad on the next one. Just to be clear, I'm not saying they will definitely sound bad, but it is a real possibility. That's just the way it goes with audio equipment. Also, I speak from actual experience. I've made this mistake myself (and plenty of others, too).

I guess that's a mistake I'll make as a part of my learning process, as foolish as it may sound, sometimes the best lessons are the one's you learn from your own experience.
In this case it is likely to save me from questionable future upgrades...
Nonetheless I do expect an improvement from the switch.
Amplification upgrade is nothing but a vague plan for the future, nothing concrete.
If I'll love what I'm hearing, no further change will be necessary (except for experiments for curiosity's sake)."

Why not give The Cable Co. a call? I find their loaner program one of the most valuable resources available. They really do make it easier for you. Personally, I won't buy cables any other way. Been using them for many years.
