New LPs with CDs inside

Radiohead, "In Rainbows" is my favorite dual format music software purchased in the last couple of years.

If you order from Radiohead's UK website you get two heavy 45 RPM LP's, CD and CD with extra material.

I burned the CD to iTunes and onto my iPod for the car while LP's get play in my main system.

I also bought the US vinyl which did not come with a CD. It's pressed at 33 and nowhere near the quality of the UK version.

I didn't buy the USA CD, so I have no comparison to offer about sound difference between it and what came from the UK.

I've heard that the "Mudcrutch" (Tom Petty's band) S/T LP comes with a CD that uses no dynamic compression. The retail CD uses dynamic compression which would be an interesting comparison.

Viridian-> You've never thought of comparing LP's and CD's??? Critical listening is a big part of choosing components for our systems and specific recordings/formats that make the music shine. Nothing neurotic about that, IMHO.

My purpose in posting this thread was partly to find out if progress in hardware & software has led anyone to change his assumption regarding the superiority of either medium. As the gap between these media has narrowed, it's interesting to try & describe the small remaining differences between the two. My own observation is that both the vinyl and CD in some of these combined package releases is of high quality, which somewhat removes from the discussion the variability of quality that one often finds from release to release in either medium. Finally, in recent years CD players have gotten so good that it's more interesting to compare them to record players than to other CD players.

The Petty release is something of a break-through insofar has he allows that purchasers of audiophile vinyl might also enjoy an uncompressed CD. What a concept!

The newest Lindsay Buckingham "Get The Screws" has a CD included with the LP.
