I can definitely vouch for the dpa's. Mine were used when I got them (from Broadway) and are over 10 years on with no problems. I use them in metal & punk shows and they have gotten used hard, including spilt beer, fat fucks with axe body spray moshing into me, etc. My coresounds went down 2x in 2 years, so, I'd say "no" to that
Btw, the issue with my coresounds was with the cabling & connection soldering. If you end up going dpa, do NOT buy them from coresound. They are available elsewhere, I'd say equally matched or nearly so, and MUCH cheaper.
