Looks like you need to expand your music collection. (Or at least listen to more CDs in general.) Every type of music out there is available on CD, including very high quality acoustic recordings. And in my experience, when you convert a hi-res file to the lossless Red Book CD standard (16-bit / 44.1 kHz) with a program like dBpoweramp, the two files sound identical, even with ultra-high-end headphones. (
This article covers a lot of information on that topic.) So it's the production process (recording, mastering, etc.) that really matters. It's like the vinyl vs digital debate. Digital is capable of far higher performance (
documentation) but since many versions of albums available on CD or as digital downloads have botched production quality, the vinyl version can still be better.
I'm saying that the production quality is what matters most in terms of sound, not the medium/format. I looked at the lists and don't care much about it. Those gold CDs are still Red Book, anyway. Put the same recording/master on a standard CD, rip both CDs to lossless, and the data will be identical.
On a related note, I've been a musician since the early '90s. I know all about the quality of live sound and how much of it is lost in the production process.
At the end of the day, it's the music itself that matters. I'd rather listen to a song I like in lower quality than a song I dislike in higher quality. That said, I already invested five figures into my music collection, so I'm not looking for more music at the moment; my focus is now on the gear side of things to make the music sound better.
