Hi,   Please add me to the list for the PM-2 loaner program.        Thanks

Would like to participate in the PM-3 loaner program.

Would like to participate in the PM-3 loaner program. I own several TOL cans, but never had the opportunity to try any planars.

If at all possible, I would recommend that you try to sample any headphones you're considering for purchase. Head-Fi can be very confusing since so many of the opinions and recommendations are obviously very subjective. There are so many variables that need to be taken into consideration...

Never owned the 600. I believe it's supposed to be a little "brighter", which I don't think would offer any advantages for classical.  

Sennheiser HD 650 would be a good choice for your budget. Also, their "smooth" signature would be very complimentary to the harsher/brighter sounding Akg's. FYI, I own both phones and with few exceptions, I prefer the 650's for classical.  

Count me in.
