Such a shame to hear that, of course hearing health is top priority. I had a 3 year old Heresy with no issues. I do recommend JDS Atom Amp if you are looking for another amp, ifi zen can is also a good choice.

Hello, they don't require a lot of power but they're pretty transparent to the source. If your source has a thin sound, you will hear that and it pretty unpleasant (harsh treble). I believe they pair really good with warm sounding sources such as an iFi Zen DAC. Had them twice in the past.

Sennheiser offers pretty good comfort and a sound signature most people will enjoy. I had been a fan for the last 4 years but I wanted to try something different. Bought and returned the K240 Studio, great sound (for the money) but they lack a lot of bass extension to me. Today I got Philips X2HRs, first impressions are very positive. To me, the HD 600 line has a very unique midrange and soft treble. Everything else isn't that great compared to the competition IMO in the same price ratio. I get your frustration but most people first hifi headphones are usually Sennys.

Forget the headphones, I don't want to blow my ears :( That's terrible.

I am very treble sensitive and the HD 560s can get warm with some DACs. I guess everyone has a different taste.

I tried it but it's very difficult to get it back :( Besided, I didn't want to destroy them. I tried the with HD 58X pads, I don't know if those are exactly the same.

I used the HD 58X pads to test the HD600s, theyguy put a terrible third party replacement pads. I was never able to get a full seal since they headband wasn't as rounded as in the pictures.
