D200- Can I use solid core speaker cable?

[Damon]

Welcome. Unless there is some impedance issue, about which I understand almost nothing, I think you should try it. I had solid copper cables on my previous Naim gear, and it was terrible. Going to a well insulated stranded copper made a huge difference, easier highs, better low end clarity, and most notably, the midrange returned to the fore, where the solid copper had the mids sucked back and dull. All the 'problem's I thought were speaker or electronic-related were a function of the cable, it seemed.

The Naim equipment is different than many products in their speaker cable preferences, but the difference was clear and immediate. The Devialet is apparently fairly indifferent, or flexible, in terms of speaker cable, so give it a whirl and let us know what you hear.

BTW my D120 took about 60 hours or so to lose the slight metallic feel to the treble, so that may soften a bit with use as well.
