No one actually knows how to lculate what speaker cable they need

Mr. skyscraper

Nice system.

The Luxman L-507uXII has a DF of 260: http://www.luxman.com/product/detail.php?id=4

For your 10ft. length it is between 1 AWG and 2 AWG. You may adopt one of the 0 AWG DIY that was brought up along this thread (parts source and labor methodes).

I know in person Mr. Yair Tamam a major designer of the Magico speaker. https://magico.net/redefine/redefine.php

For some reason he is not mentioned on this site. (Mr.) Alon is an Israeli name and they have a dealer in Israel too. I know that they earned over night a great reputation with their speakers. On my 3rd seminar held here in Israel, Mr. Tamam lectured on his vision of building a speaker…it was in 2001.

Mr.  conradnash
Please be kind to take your Bi wire subject with Mr. 
geoffkait who keeps posting on the subject (none relevant to this thread) to another place. Thanks.

Thank you for your assistance. You are fortunate to be acquainted with individuals in your field such as Mr. Taman. Must make for interesting company. I have nothing but respect for individuals having achieved that level of expertise. It doesn't come easy. Take care now,  

Michael
