Straightwire speaker cable: Rhapsody II or

Has anyone used over a period of time, StraightWire speaker cable, especially the model Rhapsody II; I believe there is a new series called Rhapsody "S".

I read on "Audio Review" the consumer blog, that the Rhapsody II speaker cable was excellent, but the IC under the same name was mediocre.

BTW, there is a pair of Wireworld Virtuoso II speaker cable for sale on the Cable Company used list Priced at 898.00 for a 10 ft. single wire pair, it seems expensive for a speaker cable design that is almost 20 years old
