Digital Audio for Dummies


As I have stated before, I'm a bit of an audio dinosaur.  I love simple.  I love reliable.  I love a high performance/price ratio.  So no surprise I'm still happily spinning discs.  Give me a nice CD player direct to an integrated and I'm good to go.

But it is 2018.  Reading on this forum about the demise of Oppo was a bit of a wake up call. Also the Lyngdorf 2170 has inspired me.  An elegant all in one box product that is ready to connect with many of the digital options now available.  So I'd like to get educated on what's out there and what you suggest.  Basically I would want to know about ripping all my CD's--exactly how that is done.  Dedicated audio computer?  How big of a hard drive/other considerations?  Wired vs. wireless.  And then what streaming services are out there?  Cost, quality, ease of use?

PLEASE keep things simple and don't assume the reader knows, for example, what Roon is.  I've seen it mentioned, but would want to know exactly what this does, how it functions, etc.

THANKS!

How can we both start with the same data on a Redbook CD and it ends up sounding better an a system like yours as opposed to a conventional CD player? I'm not challenging you here, it just doesn't make sense to me. Where is the "improvement" occurring?

Primarily lower jitter, as well as the capability to play hi-res tracks.  I recently played many re-mastered Beatles albums, all 24/44.1 rather than 16/44.1.  They sound amazing.

If you want your transport to have lower jitter, then the Synchro-Mesh can deliver that. ~20psec at the end of the 4 foot cable.  Never run less than a 4 foot digital cable because you will get more jitter.  Even coax cables add jitter:

To my way of thinking the best I could hope for in this process is to not loose any data that I have on my original CD.

CD players and transports are far from perfect, but losing data is not a concern unless it is from the early 80's.  Jitter is the biggest issue with most digital audio.  See the jitter from this transport and how the Synchro-Mesh reduces it:

Not a minor improvement.

The real appeal of computer audio is not only lower jitter (depending on the hardware), but streaming services and playing hi-res files.  I have many 24/96 and 24/192 files in .wav format downloaded from HDtracks.  Rolling Stones Let it Bleed in 24.176.4 is amazing.

With the right DAC and Ethernet interface, the sound quality will not only beat the best CD players, it will beat some of the best vinyl systems. I have customers that have sold their vinyl systems and vinyl and converted to digital audio. You can read the feedback on my website.

Thanks for the further clarification Steve.  Sure, that would bake sense as far as jitter in concerned.  And obviously streamed hi-res files can be superior.  But in that case we're comparing apples (Redbook) to oranges (Hi-res).  I was focused on apples to apples in my earlier comments.
@corelli a lot of folks have said the same thing about ripped files sounding better. One theory the lack of the physical act of spinning the disc and attendant error correction. Take that away and certainly seems possible to have better sound. In my system it certainly sounds at least as good if not better.

And obviously streamed hi-res files can be superior.

Not sure where you can get these. I only download hi-res files and own them. Download is not streaming.  Download is just a method to get the files on your hard drive rather than ripping a CD.

Streaming services are 44.1 FLAC files at best, and more often not even FLAC quality. You do not own these tracks.  They are not hi-res. This is why I do not pay for streaming services, I only play local files that I own, usually .wav files.

Got it.  Now that I think about it I see where it would be very unlikely hi-res would be streamed.  Thanks for the correction.  A necessary part of learning!
