Reviews online are true to certain extents, scientifically proven based on test statistics (Amount of oxygen in the wires etc..) and of course the perceived results in the trained ears of the people who review these cables.
My 2 cents...
Try and see whether you can tell the difference between, locally available well made cables such as Canare, Klotz, George Ls etc. If they suit your needs get them. I've been using Canare and Klotz and they work just great. Ask me whether I can tell the difference between them, and frankly speaking, I can at best tell the difference between those cheapo multi coloured patch cables and mine. But The difference between planet waves, pro-el, canare, klotz, georgeLs...honestly no.
Also no offense but the gear you're using also has to justify the type of cables you use. A lot of folks use the marketting hype of "only as strong as your weakest link" to push boutique cables, but honestly after a certain level. There's only certain nuances in a cable which your ears can pick up.
Evidence Cables cost a bomb though, they'll only be worth the dough if you and your listeners can tell the difference, and also if you've got the gear and chops to justify it as well.
Lavaman stocks loads of great cables, every single big name is there, Evidence is one of them too.

Do read up on the resources there, lot's to learn on cables, it's madness!
Klotz, Canare are available from Mr Misse, and I believe luther carries them too.
George Ls, available at Guitar77 and Davis.
Mogami, should be available at TY Music. (Scott Henderson Approved!)
