I picked up the P-75 and had a little time with it. So far It sounds very good. I do feel that maybe they should put it in a bigger box with some weights. My remote is bigger than the P-75. Many adjustments to play with. I think the P-75 has less surface noise than the EAR 834p. This may be becouse of the adjustable loading. This will take some time to play with.
