I've owned my HD650's and FiiO e7/e9 amp/dac for about nine months now. It's my only "audiophile" set I've ever owned. Lately, I've been getting the feeling that my headphones do not sound quite as impressive as they used to. I can't mark it down to any single trait; the overall sound is either getting worse, slowly, or I'm experiencing a sort of diminished return on the output quality of my headphones (which is entirely psychological).
- Is it possible to get "over" the amazing sound a pair of headphones is able to output?
- Am I just getting bored? I've heard the HD650's are boring before. Should I get a new pair of headphones? Amp? DAC? Which one(s)?
Has anyone experienced this before?
