Have these formats "caught on" yet for the most part? I consider myself an audio enthusiast -- not yet on the level of audiophile -- buying brands such as Marantz, Onkyo, and Polk; I have not yet reached the sonic demands made of fans of Conrad Johnson and the like. I purchased a Panasonic DVD player when putting my home theater system together which also plays DVD-Audio discs, thinking I would eventually buy into the format...so far, I have not one DVD-A disc nor have I gotten an itch to buy one. Movies? Sure. I have become a sound junkie --- looking for and buying DVDs with awesome DTS soundtracks and analyzing their entire playback experience through my system each time...but with music, I STILL seem satisfied with standard two channel CDs.

My music listening habits in this hobby may not warrant SACD or DVD-A purchase, either; 99 percent of my listening time (when that DOES occur) is spent making mixed "compilation" CD-Rs on my Marantz DR700 CD recorder from mainly CD singles I put into my Marantz CC67 CD changer -- a lot of my music collection is made up of promotional CD singles of songs I only wanted of THAT single, not an entire album...so would SACD or DVD-A make sense for an enthusiast, not audiophile, such as me? I seem to only crave multichannel discs when they are on DVD and Im watching cinema...not when I reach for a music CD....
