Overrated/Underrated

Underrated:  The tremendous value available from the Wireworld line.  Check the quality of cable constructs considering their price versus other brands. 

Overrated:  Kimber.  Even their Select line of cables don't have the continuity of sound they should have for the asking price.

Overrated big guns, underrated small companies and snobbed ones.
Some of my list, ML, Wilson, B&W, Focal, Clearaudio....overrated
PMC, Bryston, Lavardin, Leben....underrated.

Please... Cables! Cables!!! 

Virtually all cables have been becoming overrated/obsolete since the appearance of Bluetooth and similar technologies.

I've been looming up both my rigs lately with Blue Jeans, ergo Canare 4S11 speaker cables and Belden ICs. BJ applies their magic sauce terminations.

I'd say underrated simply as their prices are nutso low. 

I love my Schmitt Custom speaker cables.  Very nice Mom & Pop shop. Great customer service.
