Hi Dale!
I am big into the high rez audio. SACD's and vinyl are the staple for my ears. The quality of the remaster and the high rez format are evident on most quality home systems.
There is a fair amount of SACD's that are released regularly. Many times it's jazz or classical. But Mobile Fidelity releases a number of pop and rock classics regularly. Foreigner, Little Feat, Santana, Stevie Ray Vaughn, Yes, Megadeath, The Band, Pixies, The Cars, The Byrds, Doobie Brothers have all been released on SACD within the past year. The real bonus is that all of these are limited edition releases. Most of this stuff sells for more money than you will pay for them in about two years. Search for Alison Kraus "Live" on eBay. That SACD routinely sells for more than $100. Plus, all new SACD releases are Redbook compatable.
For those of you that think SACD is dead, look at all the high end SACD players that continue to be release daily. Marantz, Esoteric, Ayre, McIntosh, Denon, Cary, Krell, etc. all have high end SACD players in their current product portfolio.
I don't listen to music in 5.1. Most SACDs are no longer offered in the 5.1 format. Some of the earlier release were 5.1 compatable.
