Jylee, you are correct. That was my original question. I also wonder sometimes that maybe SS is better than tubes currently - but maybe are we held back by our own "habits" of listening, such that anything other than tube seems "less" in our world!!
Semi went to the extent of size and Undertow mentioned the iPOD. When I mentioned advancement, I did not mean SIZE. Look at my evolving system - I am going from an integrated to a separate preamp and amp. I still cannot switch to iPOD or data-servers. Maybe they are as good as the current mediums I am using - but maybe I am biased to my current medium and that is preventing me from switching to digital files.
As for music as an art - I completely understand. In fact that is what I "try" convey to my non-audiophile friends. But remember if you can create art using more advance technologies, that can lead to betterment of art - why not explore it? Cave men used rocks, charcoal and other items to create art. Why did modern man come up with ink, paper and other stuff? Maybe SS audio has not been fully explored.
Atmasphere, I understand that humans did advance to Tubes. But looks like they are stuck there :-)
