Audiogon speaker wire gurus, please help me

OK, an unbiased opinion from someone who doesn't sell anything.

IMHO IC's and speaker wire should be neutral and allow the electronic's signal to pass undistorted. A question for you to answer to yourself. How do you 'know' the cables in your system are responsible for your systems shortcomings?

You are asking for warmth - which suggests to me that your present system is too cool for you and that you want to bend some part of the frequency response which (for you) embodies the warmth spectrum. IMHO if your cable adds sense of warmth it does so at the expense of other frequencies, like the upper mids and highs which will seem to be rolled.

You want cable which will provide for the impression of expansion of soundstage and air between the instruments. Often when this is achieved it is done by emphasizing the upper mids and highs and concurrently reduces the sense of warmth inherrent in your electronics.

You've got a bunch of individually good components. But, if you find the sound wanting seriously in the areas you outline, I'd be looking at component synergy, not wire. Now if you are talking about typically nominal acoustic differences I'd be trying to find the most neutral cables available and I wouldn't buy anything until I heard it in my system.

FWIW.

I think Alpha Core MI2 Veracity is the undisputed champ of econo wire and has been for years IMHO

Without mentioning any brands I would have to caution you about spending that kind of money on speaker cable. I think the money can be better spent either elsewhere in your system or by dropping $500 on some really good wire and giving the rest to charity. I don't really see the point of dropping that kind of dough on wire.

the purpose of listening to music on a stereo system is to enjoy it, not necessarily achieve neutrality. some people don't want neutrality. they mant some color, like puttting ketchup on your stake or three teaspoons of sugar in a cup of black coffee.

it is best to listen to a bunch of brands and then gradually determine those attributes of sound which are more important and also determine what aspects of sound are less important or unimportant.

there is no substitute for listening. try to find a dealer or the cable company to borrow speaker cable.

your ears are unique. you can't rely on another person's perception.

I agree with dodgealum- too much $ for wire. Try as amny as possible with the option to return from a local retailer or private seller or friend. Find what you think is best and spend some cash on LPS or Cds, etc.
Good luck!
