More power? That doesn’t make any sense. HD25s and your average mixer puts out enough volume to do permanent damage. Why on earth would you want to go louder? Why do you think that those you listed do?
I got the HD25 and the HDJ2000. Love 'em both to death!
The HD25 is more “active” and “energetic” whereas the HDJ2000 is more “laidback” and really packs a punch.
But when push really comes to shove.. I’m grabbing the HDJ2000!
I’ve used just about every headphone manufacture there is. The problem with The Pioneer, Sonys and Technics products. The right channel usually always end up crapping out over time. After taking apart my old pair of Pioneer’s. I learned the failure is due to poor wire routing and a wire chaffing against a metal bracket when fold and un-folding the headphone. The wiring problem could be solved if the manufactures put a piece of electical tape around this wire. These headphones are almost impossible to put back together once taken apart. I treat all of my gear pretty good. I take care in packing my gear for shows and events. At most, I’ve gotten about a year to year and a half out of the Pioneers. The life span of my technics about the same. The last pair of headphone i purchased were a pair of The Allen & Heath headphone. I think i spent just over $200 for them. That was about 3 years ago. These headphone still sound as crisp and clear as the day i bought them. They are also the best headphone i’ve used for playing on loud systems. They fit tight against your ear so you don’t have to keep putting constant pressure on the cups, which is one of the main causes for hearing damage.
