What makes a system compelling?

It took me years of costly experimentation with both tubes and ss before I settled in on the new ARC stuff (which sounds more like solid state on the extremes but retains gobs of tube magic in the mids and how the images are portrayed..full, round with 3-D action). I have experienced what tbg has many times over up until now. I don't quite understand it but the synergy I have going hits the mark for me...not completely realistic, but better than most seats at the kimmel center in Philadelphia!

In my case my system becomes most compelling when I listening to a recording I would usually have little interest in. I know that sounds stupid, but it is true. It is then I am most conscious of listening to the effect my system has had on a recording. Often I find I will like the sound of these recordings even as I find little of merit in the actual content. It arrives for me as a sort evaluative opportunity. Even then, I would not go as far as saying that I will necessarily percieve this as an improvement in sound quality. There has been a change, and I hear it and think about it. There have been occations- so many occations, when I have heard a recording that I have consistantly enjoyed but could not make out the vocals or instruments because it all became confused in the mix. I could not capture it. When my system has suceeded in untangling this for me I am impressed and I am thankful.This music becomes all the more to me, and I get this much more of my music collection back. I get to have this from time to time- clarity, and I value it and the means by which I got it.

A system becomes compelling for me when I no longer focus on what its is doing to the music that is being played on it and I become one with the music.
