So i just bought a Sennheiser HD600 with a upgraded cable cardas 15ft. I hope i will enjoy.
Philippe, the HD600's are excellent, maybe better than the HD650's for some people's ears.
Enjoy your headphones, and resist the temptation to get a tube amp.
I do have a warning, HD600's and HD650's may sound overly blissful and magical when driven from a tube amp. So, don't buy one. Wait...
So need, I did my time on HeadFi. Far to much bullshit on that site for my taste.
No kidding. There is some commonly held belief that EVERYTHING needs to be "burned in". I can understand tubes, maybe, but cables, headphones, solid state amps -- heck, even when people put new capacitors or resistors in their modded equipment they say "Well, they don't sound that good, but after listening to it and letting it burn in, it's starting to open up"
WTF? Maybe you're just learning to appreciate the sound. Just sit back and enjoy...
