I have Duelund 16 GA as speaker cables for my Analysis Audio Epsilon and Air Tight ATM3. (1,5m)
DCA16 GA inter connect between Pre and amps 2.0 m)
DCA 20 GA interconnects between pre and DAC (2.0 m)
DCA 20 GA betwenn Step up and pre (1.0m) shielded by Chris at Paers Connexion. It has been longer to burn in to and take some relative brilliance off.
Next step is to intervert 16 GA for the 20 in the pre to amp circuit.
I Pre ordered the 12 from Part Connexion for the speakers as I am curious. I will see what it brings to the table.
When I am sure of all that I think my quest for cables will be over.
