thinking of getting the best ultrasone and without paying the price for the ed9., so go for the modded alo780 or the pro2500?

The bass on the HFI780 and ALO780 is more powerful than the PL2500.
They both (780/2500) tighten up and become more controlled with more hours, but the PL2500 bass volume decreases more with hours and levels off, and I haven't heard the 780 drop off yet. The ALO780 had more bass control and definition at 50 hours than the HFI780 at 200 hours when I first compared them. With 36 more hours on both the ALO and stock ones, they continue to improve in that area.
Also, the ALO ones never showed the dip in performance during burn in that the stock ones had between 36-75 hours. I suspect that was the diode board. They are at 255 vs 85 hours each, if my math is right, and with the stock ones it seemed most of the changes were in the first 150 hours, after that it was just adding more refinement and control. I am now about to send mine off in an hour or two for Ken to mod, then I'll return these later in the week.
