I bought the same wire a few months back after using Monster 2.4s (I think that's the callout) for a dozen years. The Monster has hunkin' momma wire size. Looks like #8 or so. I had no issues with it, but as you know we all want to spend some more cash on our system every so often. The Dueland is great on the high end. And I think light on the bass. I actually started a thread about wire size a couple weeks back to feel how others felt about wire gage and speaker size. I'm gonna re-hook up the Monster on the low side (speakers are bi-wireable) and see if it gives them more of the great bass they originally had. Speakers are Infinity Ren 90's powered by a Krell FPB300cx. Then I may try the Dueland 12 gage. I just feel the 16 gage can't handle the power requirements. I relate it to trying to run a skill saw using a lamp extension cord. It'll go round and round, but if you want to cut some serious wood, you'll want a good #10 extension cord.
