Whenever the Monster Cables conversation crops up,...I like to direct people to this graphic, which is admittedly outdated as Monster has come down on their prices,...albeit still not competitive.

Then I like to point them to this article.
http://www.audioholics.com/news/industr ... rikes-backLastly I like to bring up the "fact" that for a while they were using slightly oversized 1/4" plugs on their instrument and speaker cables. This may have been a QC issue or intentional but the result was essentially the bigger plugs were wearing out jacks to the point that only the slightly oversized plugs on Monster's cables were the only ones that would work on the slutified jacks. As far as I know Monster rectified that situation years ago and I will cop to not having any actual real world experience with this,...but seriously,...if those are more than mere rumors,...that's bullshit.
Last Christmas I had a $100 Best Buy gift card and as I was trying to get my pedalboard powered I figured I'd head up there and see what was available in terms of power strips,...hoping to find something compact to put on my board. The only viable options they had were Monster Products. I bought something else entirely instead (MK Multimedia iRig).
Even if Monster Cables are in the clearance bin at Guitar Center for cheaper than the equivalent Live Wire or competing instrument, patch or speaker cable,....I'll still pass on them.
Their headphones may be the bee's knees,....but I will never know since they aren't getting a dime out of me.
