I thought so.

I think when 44.1 kHz was selected for the sample rate (I still don't know how they decided on such an oddball frequency), there was too much faith in the Nyquist/Shannon Sampling Theorem, which unfortunately only holds true for steady state signals. But music isn't steady state. The theorem falls down with non-steady state "transient" events, where "ringing" is introduced in the time domain (using the so-called "perfect" sinc filter). So the "perfect" sound couldn't truly be perfect.I've had debates with theoretical engineers who thought I was a crackpot for questioning this theorem for audio application..... They treated the time domain issues as a strawman argument.

it's forever.
Even live, maybe I don't like the type of strings that a player is using, etc. Then even this perfect "playback" is "flawed".
I eventually found that my goal is not perfect sound, but maximized enjoyment of music.
The "forever" part made those yuppies reach for their wallets. A good investment is nothing to sneeze at.
You need a nice (literally) clean CD, played on a Read Until Right transport with vanishingly low jitter, such as Parasound's CD-1, a S/PDIF cable that does not mess things up, and a superb DAC with sophisticated filters, such as Bricasti's M1.
Under such conditions, CDs can be astonishingly good, especially CDs that were themselves remasterings of golden-era master tapes.
Yes, an unedited raw pure DSD file will sound better--but in almost every case, there will be a better performance of that particular piece of music.

SO few DACs and CD players truly bring the medium to its potential.
Prior to the experience I had with the Wadia 7/9 transport and DAC, I once thought CD was hopelessly inadequate for true high-fidelity playback..... Since that experience, my everlasting quest to replicate that Wadia experience.
It wasn't until I attained the Prism DA-2 DAC, and later the Don Allen/Philips CDC-935 CD changer, where I thought I could live with only CDs as my playback source. Yet even there, I still give vinyl a slight edge overall.
In regard to the time response/frequency response compromise with CD playback, I think the key is attaining a happy medium where neither flaw can be readily noticed. I once thought this couldn't be done, but I think I'm close.

Reebok can sound great. DSD and other formats can sound different, but better?
Setting aside the truly hi-res workflow, from recording to publishing (which still seems rare), are we really getting any more music or even verisimilitude from hi-res manipulation in the mastering chain if it's not captured at source?
Otherwise we may as well argue that we'll never, ever have perfect anything - or simply down tools as a species and camp right here, where we are now.

I think redbook can be superb with good equipment. My vinyl sounds great and my cd's as well as streaming are wonderful. I enjoy my system no matter what medium I play back in and yes I have heard Hi-Rez downloads all the way up to DSD and don't find any more enjoyment from them.
