i need 20 meter speaker wire, decent quality

Fwiw I'd consider moving the front end gear closer to the power amps.. You've spent a HUGE amount of money on your gear. I don't see why you would want to hobble the performance by compromising on the quality of the cables because the distance is so great. That said if you just can't move the front end closer to the amps then long Balanced interconnects are the Only way to go. Balanced cables are designed to be used in long distances with minimal loss.. speaker cables that long are just the wrong way to go. Good Luck.

I can't make any promises, but I suspect you could negotiate a more favorable price by telephone. Keep in mind that the MI3 was developed at Krell's request, and they have a great reputation for working with Nelson Pass's Thresholds (with the provided zobel networks). I suspect that they will work quite well with Pass Labs as well.

Merrill;
I would not recommend using the standard 12 or 14 gauge solid core "house wire" as Morrow suggested as a speaker wire. It has heavy insulation all around, and sonically it is rather harsh and edgy. I have experimented with it for both AC cords and D.I.Y speaker cables with poor results. I tried the Anti-Cable solid core wires a few years ago, and was very impressed by some things it did in two different systems I had, but found it had tonality issues which I could not live with. I later tried a similar solid core cable (but cryo-treated) by JW Audio. It had none of the tonality issues that bothered me with the Anti-cables, and the detail and clarity was the best I have heard in my system at this point. My previous 6 foot pair of wires retailed at over $1,200, and I quickly sold them for half that amount. I was quite shocked that a $60 pair of cables could sound so much better in comparison. They do offer a 30 day trial, but you might want to see if they will still do so on such an unusual length. At $10 a foot, you will only be looking at a bit over $600 for a pair. That would be far more reasonable than a high quality set of 60+ foot interconnects!

Hey Shutterbug thanks, I will check out JW Audio.

btw $10 a foot needs to be doubled at Anti cable. And then when they do the labor of braiding and soldering spades, its over $1,800.00. for a shotgun bi-wire

I did not know you were were looking to bi-wire. I would guess, in that case, you would have to double the price for twice as much wire. I would not think that they would have to charge quite so much extra $ for 4 more spades on the speaker ends. I could understand a few extra dollars, but not four or five hundred dollars. If you have carpet on the floors where you are running them, it would be a good idea to raise the wires off the carpet a few inches to avoid any static interactions. A simple solution is to purchase some (in your case... MANY) inexpensive, round, 3 foot wooden dowel rods and cut them in half to make some simple "tripods" to keep them of the carpet. Home Depot sells approx. 3/8" diameter ones for very little money. You can even stain or gloss them to make them more attractive.
