Well, my band is (are?) 1964 Ears endorsing artists.. so I'm a tad biased on 1964... but I had been using Qi's for about 2 yrs prior to that happening - and absolutely loved them.. upgraded to the A8's w/ the endorsement.. Awesome IEM's.. took a bit of getting used to as the ADEL tech almost makes them behave like IEM's w/ ambient ports...
I'd buy another set in a heart beat..
I also love my G3 wireless.. yes, I took lots of twists and turns to get there and they are not cheap - but neither is the Axe.
I gig frequently for a weekend warrior (75 gigs in 2015 - haven't tallied this year yet).. so the $$ was worth, and I get pristine audio night after night. We use IEM's no matter the set up.. My mix is 95% consistent gig to gig.. The xmitters are in the same rack as the console. We power jup and go..
