I believe that music, art, theatre, literature are the ultimate achievement of mankind. Spending thousands on a book won't improve it's enjoyment, original artwork by a master is beyond our humble wallets (and we can see them free in any major gallery - how brilliant is that?) - but by throwing a few humble thousand pounds at audio, we can appreciate recorded music at it's best.
Would I spend £200k on a hifi, or more? No.
I agree that this is a clear expression of the meaning of an artistic experience, it's value. All I would say is if you don't buy the book, buy the picture, how is the artist to survive.
I love music, live and recorded, but also books an paintings, sculpture. If you think most musicians are poor, you should look at artists. It's near impossible to make a living, unless you are a genius and most of them are'nt recognised till they are dead. So buying pictures, sculpture, keeps the wolf from the door, where buying a print or visiting a gallery does'nt. There is something special about an origonal work too.
I know this is really getting off the subject
