Is it important to long demo or own HIGH END gear to have a fair accurate view about it?

+1 Like I said earlier, love at first sight. I'm not sure if listening for days is going to do anything other than get you used to the new sound of the system. Maybe that's the point. Maybe I'm too quick to judge, or impatient. Or maybe, I'm so satisfied with how my rig is tuned for my taste that anything that sounds "off" is not tolerated.

@bigkidz ...we advise people that if they do not hear a significant difference within one listening session - probably within 5 minutes...

That, notwithstanding, it is critical to hear the test component in your system, in your room.

I only ever comment on something I've heard. Equipment, artists, or recordings.  However, some components are overpriced, and seem to be aimed at the ever growing cohort of the new rich. It's fair to say that you probably obtain a more reasonable perspective on a piece of equipment when you're in possession of it for a longer period of time. Nevertheless, I'm a love at first sight man. It it doesn't wow when the needle drops, I'm out!
