Anticables, Morrow Cables SP1 or PNF Cables


These are all roughly the same price – any opinions as to which would be more suited to large orchestral works with bi-wired Quad 11L bookshelf speakers?

I find that the Quads seem struggle with passages of music which involve dense orchestration. Which of these speaker cables might help “open” the sound a little?

stmike,
I'm not sure how to do a pm but will let you know within the next couple days. They are a 6 foot pair with spades. 
Strangely, there doesn’t seem to be a way to message anyone on this forum unless responding to a for sale ad.  The length is good for me, but I forgot to ask whether they’re biwires, which I want. If so, I’ll try to find a way to contact you.
