Interconnects: solid or hollow core wire?

After using various solid and stranded cables over several decades of audio madness, I recently found a synergistic match to my current pile of electron manipulation gear in a recent iteration of relatively inexpensive Audioquest solid core speaker wire...I'm not sure why people want to spend 3 to 10 times the price of this stuff on anything else as it lacks nothing except quasi entertaining mysterious voodoo...if a cable is light on the last octave of bass and musical "pace" (meaning timing I suppose) I can only imagine it's as thin as a polyester microfibre, or the designers blended condor guano into the metal formula. I'm not a cable luddite and if I had unlimited cash I might buy some extreme $26,000 per inch cable just to marvel at how it looks (and engender geek cred in spades, as well as disdain from sane people), but otherwise I remain in the world of the actual, and welcome others along for the ride.

Pmboyd: I use Crimson throughout my system...interconnects and speaker cables. You can see them in my "virtual systems".

To address the bass issue that Agisthos mentioned, DNM has developed two different solid core speaker cables. The Precision Speaker Cable (the thinner of the two) is designed to be used for speakers above 90db. I used this in my old 300b to Lowther speaker set up with great results. The Stereo is designed to be used in speakers that are under 90db. This is a "thicker" cable that DNM made for high current amps and harder to drive speakers. DNM found through customer feedback that the Precision wire wasn't doing all it should in this configuration. I am now using the Stereo in my curent set up and have no desire to change it out.

Hey Rodge, Yes I am using the newer, thicker DNM wire for 'normal' speakers.

I should clarify, when I say it lacks the last octave, I am being unfair, because this is only in comparison to my Downsize Audio 2" wide copper ribbon cables. They have an extra octave in bass compared to most speaker cables, not just DNM.

The Downsize Audio ribbons are the best speaker cables I have heard so far, but they are 10 times the price. For the money the DNM kicks ass.

I have found that solid core is better than stranded in either IC or speaker cables. But then ultra thin ribbon cables are better again, but more expensive.
