Higher end value cables

 ..."but my reading indicates that bjc is terrific for mid to lower fi gear."

The reading is the problem.

Belden 5t00up 10awg equals super hi-fi exotic cables with less resistance, capacitance and inductance (therefore the most transparent, minimal insertion loss at all frequencies) and A LOT LESS anti-physics compounds. 

Suggest:

Always try cable in your system to make any determination.

See JPSLABS.COM    their cables are excellent.  

Looking at virtue cables right now. Have you listened to them ps?

I second gcp's suggestion.  Virtue Nirvana are BIG bang for the buck, and then some.  You'll also find Jason a completely stand-up guy who is truly dedicated to providing his customers with excellent cables,  at real world prices. His craftsmanship is also exemplary.
No affiliation except as a very happy customer.  Right now I'm burning in a pair of the Nirvana speaker cables and am loving it.  Once they have another 80 or so hours on 'em, in go a pair of his IC's from preamp to my mono tube amps.
