I have HD600 and an Antique Sound Lab Tube head-amp.
Headphones can't be beat for “quite time” listening, when others members of household are doing their thing. Also, for some critical listening they are excellent. No room interactions to cloud detail. In this regard, headphones are an excellent tool for the purpose of speaker setup in determining additive or subtractive issues.
However, there is no way that headphones are a substitute for a good speaker system...even the best don't do stereo spread, depth or bass well.
