Agreed jond. Salectric has built a great system and I value his opinion. I value his opinion so much I am a tad confused how the Duelund wire was not at least pleasing to him. Goes back to system synergy for sure. 
Thanks guys but I am not looking for compliments.  I just wanted to provide a little balance, that's all.
@salectric understood just checked your system out and was blown away. And jealous of your Deja Vu speakers I am a customer and big fan but the speakers are to big for my budget and my room!
Thanks all for your recommendation!

I was just curious?   Any members try the duelund foil 1.0, 2.0 or 3.0 flat silver wires?  Can it be use as main speaker wires?? Please advise??
