I can't speak for others...but for me "resurgence" is the correct term...when I first got interested in hi rez titles I got rid of a lot of my "old" cds...much like I did in the past with other formats when a newer one surfaced...what a mistake that was...I ended up buying a lot of those same CDs back....I discovered 2 things with my "new" hi rez formats...all of them weren't superior in sound as I thought going into the hobby...and the second and most relevant discovery which applies to the thread topic...hi rez is limited in the number of titles that I can purchase...this is where CDs really shine...I didn't do a Wikipedia or Google search... but I would venture to say that there is more music(titles)
available(Key word) on CDs than any other format...
I have stated this recently in a post...old CDs of titles that aren't available...especially in the used market...will be sought out heavily by music fans...which I'm doing now...probably more so in the 50+ demographic...and if you do your research you can find titles that will never be offered in hi rez...but are available on CDs with mastering that is more pleasing than many new releases...I look for specific CDs that you can find on Ebay...you can usually find the barcode and catalog number of the title you want on Ebay...I spend hours looking for some of these titles...partly because I enjoy it
.....with me sometimes the "hunt" is almost as important as getting the CD...
If you have an open mind and aren't pre disposed to the "metrics"(24/96)and you do your research...there is a ton of GREAT music that isn't available in hi rez and can be obtained on CD..and with these newer receivers... with various sound modes.. you can tailor the sound to your preferences....there are quite a few members that enjoy CDs...like Snood..hwkn...and Quad Linda...
