dynaquest: Truly happy that you enjoy your system and the cables you are using. In some ways I wish I'd never tried better cables than what I was using that were essentially straight 28awg, 22awg, 14awg, 12awg, etc...way back; the problem is that what I've come to use as my reference cables have brought so much to the table in my system to my ears and people who have come over to listen, not being told anything of price, config changes,etc..., that I simply have to have them in the system. Every time I've tried to subtract them and go to stock cords (which I've done several times over the years and often had to live with that for several months for various personal reasons), sound stage, imaging, musicality of instruments, voices, etc....becomes literally a shadow of how the system performed the days before. This is according to what I've heard and those with good ears that I've allowed to share in my system in my home.
You'll notice that I don't go for the reviewers' current flavor of the month in my system at all or cables....there's a reason for that. What I have kicks ass and while they cost well more than I EVER thought reasonable as I used to think like you do many years ago, I cannot deny how the system sounds (and measures mind you) when I have 'the good stuff' installed.
You are going to laugh at this response I'm sure and think me another of the fools who have drunk the kool-aid, the snake-oil, whatever. Quite the opposite actually as I was a huge skeptic for a long time up until a few years ago. Regrettably, my hearing and an open mind now having me using those cables that you would claim don't make any difference; penalties to me I guess both figuratively and financially. With I could get away with 14awg or whatever :-) !
I also side with gbmcleod on cables needing to settle after shipment or transit, not because some dealer or cable maker told me to, or because some fan-boy on some forum said it was so, but because I have found many times, with certain topology cables, particularly those with woven/intertwined helix geometry for multi-stranding conductors or particularly for any cables with heavy ribbon compliment, that they frankly have to reach steady state and their capacitive properties need to stabilize before they start to sound their best. This is usually the first 24-36 hours and sometimes has been as few as 12 depending upon the cable, the metallurgy and the topology. My father was a metallurgist, a musician and an audio hound who NEVER invested in anything but bargain cables from Radio Shack or the local stereo shops beginner's rack; he would tell me that any metals that have been through extremes in altitude, temperature or radical movement have their physical properties changed a bit and they have to acclimate to a certain degree to their current environment. Enough said on that....
dynaquest: I'm sure you are enjoying this response as further proof of your position. Anytime you want to spring for a plane ticket and drop by with your cables, you are welcome here. I'd love for you to do some A/B here with those I'm running and bargain cables and let me know what you hear! BTW...I'm not joking!
