Most underrated composer of 20th Century?

Map, you are right of course.
But from the perspective of one who hears the footsteps of the Grim Reaper coming ever closer, what Classical can do for you at its greatest, say ,a Bach Cantata, The Monteverdi Vespers, a Josquin Desprez Mass,a Bruckner Motet
or a Mozart Quartet, is to focus you on the eternal and polish
your mind and soul for the coming journey we all must make.

Even the best of the adrenal raisers don't do that.

Schubert, out of curiosity, if time spent on listening to music is so precious why waste any of it posting opinions on the internet?

I'm thankful that I have no such constraints and can listen to most anything that interests me including stuff by Klami, Bantock, Ives, Massenet, ad infinitum, without guilt that I'm not listening (again) to one of the 'greatest composers' or 'greatest compositions' if I were even educated enough to know which ones these may be.

Perhaps ignorance can be bliss after all. :-)

Newbee, because I'm a deeply flawed person who often does stupid things.

Ignorance is not bliss, it is hell itself.

Schubert, Britten is certainly well known and well respected. So why don't I hear his music unless I cue it up myself. That is my point. Something is wrong here. If he is really what people say he is, why is it that at age 60, I have never once heard any of his music in a concert hall, and never once head one of his quartets performed in a chamber series?

As for the transport question, I have no idea which of the 3 might be best as a transport. I do know this, if I were looking for a transport, the PS audio perfect wave would be on my list. I really like the approach of reading, correcting, then playing back what is held in buffer. It seems to me that the approach offers some of what well executed computer based systems can do without having to go all computer geek to pull it off.

Tortilladc, your comment is insightful, and I suspect that you are very right. But great music that endures must by definition have meaning and value outside of a narrow context. Laugh In was a hoot in the 60's, now it is just plain silly tripe.
