I use monster. Ive tried 1,2,3 and thx ultra monster ranges. The more you spend the better they get of course.
More cash does not always equal more noticable improvements but I still find it hard to take Monster seriously while they include claims like this one :
'Gas injected cellular dielectric for high velocity'
Glad you are enjoying your Monster cables but in general there are better places to spent your money than with them, Thor and IXOS would be two suggestions.
