I've recently acquired a suhr reactive load at IR to use with headphones while playing at home (which has been more often as of late). I'm using a pair of sennheiser HD280 pros and have had horrible results thus far. It has my perplex'd sounding brittle, fuzzy, and unresponsive. I've heard a headphone amplifier helps for high impedance headphones (I believe these are rated at 64 ohms). For those who have used the RLIR do you believe that this would solve the problem or should I look into getting a better set of headphones? Does the RLIR sound terrible regardless when using headphones? I've heard many amazing demos of this unit so I have a feeling it shouldn't be this bad.
