And here I am going to shamelessly quote myself from another thread
At the end of the day, it depends on how much
obsessiveness and pathological compulsiondedication and commitment one is willing to bring to the table.A purpose-built listening room becomes a necessity if one is to even hear the difference better gear makes. That room alone can cost $250K or more, though it doesn't have to.
I don't have a dedicated listening room and I don't want one. I sometimes listen to music 12 hours a day, so I need to do something else while listening, namely, in my case, work. That supposes, by definition, a very imperfect room, which in turn limits how much better gear I can get while still reasonably hoping to hear significant improvement.
But I wouldn't last an hour in a dedicated listening room before I got cabin fever, so I'm more than willing to live with what I have as it lets me listen to music for another 11 hours, and ultimately listening to music is what I'm here for.
