Who listens primarily to Redbook CD?

Cd's are an object lesson of respecting scientists dealing intelligently with objective reality, rather the narrative folks speculating that other formats and sampling rates must sound better.  Mathematically, Redbook is solid, revealing its glory as better processing evolves.

Of course, Redbook will also faithfully store badly made masters, and faithfully deliver its information to badly-designed downstream equipment.

@ electrostacker:

Exactly.  Fidelity ends when the original recording session ends.  Wrapping an analog recording from the 1970's in a 24 bit package does not make that recording have greater fidelity. And ripping a CD to 24 bit does not magically make it sound better than the redbook CD (are you listening Neil Young?). 

True Hi-Rez recordings must be recorded at 24 bit and retained at 24 bit throughout the recording and post production process. Almost all "high-rez" recordings being sold today are not better than Redbook.  Just another scam to get us to buy our music all over again.

I received my PS Audio DirectStream Memory Player, replacing my PerfectWave Memory Player, hooked to my DirectStream DAC via the I2S connection.
The new disk player has a number of advances, hooked to a DirectStream DAC it has the ability to output native DSD directly to the DAC (will need to wait on auditioning that, my DAC is an early model and PS Audio will be doing a hardware update for me, for free).
The improvement in the sound quality of "regular" CDs is immediately noticeable!  When a drummer is well recorded, you can "experience" the timbre of ride cymbals vibrating, not just the sound.  It also seems to have more "distinctness" to the individual performers.  The bass is better controlled and defined.  And the soundstage is improved.
Can't wait for my DAC to be returned with the updates.  But so far, the sound of "regular" CDs is awesome!
Great job PS Audio!

I listen to physical CDs... and SACDs... and digital files... and vinyl. I used to listen to R2R tapes but my Teac A3340S didn't survive my last move (sob!).

Why limit oneself to only one format?

Why limit oneself to only one format?

Because you prefer to invest your limited resources in getting the best sound you can from one format, rather than mediocre sound from several.
