Greetings, .6mm equates to about 22.5 awg. With 23 awg being .584mm and 22 awg being .635 mm. Probably some Cardas wire. George uses a lot of in between gauges. That wire is a bit large for my taste. It my have a bit too warm sound and lack dynamics. Other than that you might want to try the Chris Ven Haus design. It is excellent IMHO! Happy Listening! John
