Abso-bloody-lootly, Kev...
Opinions are just that...opinions...
However, Pioneer sell their CDJs as professional kit...
When I buy any pro kit (amps, speakers, effects, decks, etc) I expect the level of support that goes with the price tag and the pro definition...
If my HiFi CD deck goes down, then it isn't so important if it gets fixed this week, next week or next month...Indeed, if it only cost £150, it matters less if it never gets fixed.
On the other hand, if I have a pair of CDJ1000s that cosy £1500,odd, and they need a *fuse* I don't expect to have problem getting them fixed a]promptly and b]at a reasonable cost!
The acid test of pro gear for me (as a rig owner) is what happens when you need the back-up.
Some companies bend over backwards to help sort the problem: Harman (C-Audio, Crown, JBL, BSS, PD, Studiocraft, and several more) Formula Sound, Technics/Panasonic and Numark have all been excellent...Even if the equipment is long discontinued...Harman even fixed 2 of my C-Audio amps while I waited and watched so I could complete a gig without having to borrow or hire any replacement gear!!
Haven't (yet) had to test out QSC or Behringer as their kit has been reliable and the only Behringer bits to fail were swapped out by the dealers under warranty.
OHM, on the other hand, along with Pioneer get the wooden spoon for customer service. At least OHM understand about "pro users"...but they muddied themselves by arguing with me rather than sorting out *their* problem and then refusing to service my (old) amp!
But Pioneer are by far the worst...expensive parts, unknowledgeable and rude customer service people, poor service agents and zero spares availability in the UK.
