I just listened to M83's very nice and highly praised album, RedSeas&LostGhosts. It hit me that this type of music is much more common now than 30-40 years ago. I have a very high end system (cost > $20k). This album sounds good on my system but honestly I think it would sound about the same on a system at 1/10th the price. The reason is that the design of the music doesn't have much to do with the actual sound of instruments or the way they are artfully played. The music is wall of sound stuff. Good wall of sound stuff. The move to production values and design of innovative soundscapes makes great sound less possible or less important. If you are 25 and this is what you listen to, an iPod will do.
