I love my HE-400, have had them for 10 years. This is the original model - not 400i, 400S, or 4XX. They're great and I can't pick any specific flaw with them. But I have never heard the audiophile things that audiophiles always claim to hear in their multi-thousand dollar setups. I don't think HE-400 have particularly remarkable sound stage, instrument separation, or detail resolution.
I have also owned Sennheiser HD800 (not HD800S) but quickly sold them. I couldn't find anything that HD800 did better than HE-400, but they cost over twice as much and have clearly poor frequency response that I've had trouble correcting.
I would like to upgrade to headphones that are clearly better than HE-400. What models would you recommend for, say, below $1500? I have read a couple HE-560 v4 reviews, including the one from Amir, and it sounds like they're are better, but not sure if better enough to be a solid upgrade.
I'm not at all set on Hifiman or planars, all I care about is sound.
