Debatable, for sure.
What if you have a system in your listening room, and one in the garage (for example), and you happen to listen to them EXACTLY the same amount of time. Now, the definition of "main system" is less clear.
So, if listening time is equal, which wins out? I say the more powerful system.
But, what if they are identical in power output?
Then, the speakers should be the deciding factor.
But, what if the speakers are the same model (allowing for discussion on the different versions of the HPM-100s<g>)?
Ok, so speakers and output are the same. Did you purchase both originally, or one originally and one as a used system?
Then, I think, the original purchase wins, as you would have owned it longer (most likely).
But, what if both were used components? Same rule - which have you owned/used the longest?
Do others listen to the one in the house, and are you the only one listening to the one in the garage? Then, the house system gets more usage. But the question was regarding YOUR main system.
So, what is a main system?
