Yep, the PMA-2500NE is a corker. As much power as you could pretty much every need, loads of inputs and I found the DAC to be excellent. The only downside is the sheer size, make sure it fits on/in your rack.
So much so, I now have an older PMA-2000IVR, pretty much the same amplifier inside without the DAC. Years ago, before both I had the PMA-2000AE, the middle model, again, as far as I can tell and remember, pretty much the same as the PMA-2000IVR. The main difference operation wise, IIRC the 2500NE does not have a pre out, where as the older models do. I remember the built in phonostage being great in the 2500NE and 2000AE, I've not had a chance to try it in the 2000IVR yet.
