CD v Streamed

Uncompressed CD audio will take about 10.6mb per minute to play, to stream that takes big space and dollars to stream an album, see what your streaming company’s takes mb per minute to stream, find out and post up here.

I hear CD’s are better, I get better dynamic range from CD every time it’s A/B to me, now that could be that the streaming companies are using the "later compressed re-issues" of the same albums, you can find that out here
Or that the streaming process itself compresses the music to save "streaming size" to save big dollars even if in small amounts.

Here’s a video from the CEO of Disc Makers Pty Ltd, yes he probably also biased because he manufacturers CD’s and vinyl, and is a very bad dancer.

I tried out an Optical Media Converter today. After reading threads about this being an effective improvement I thought I would try it. Some months ago I put a network switch between my ROON server and the router which improved the sound. Still, 44.1kHz/16bit streaming was not quite as good as CD or the Ripped CD FLAC files on my server. The Optical Media Converter consists of two boxes with an Ethernet cable going in box A and fiber cable going out to Box B and then an ethernet cable going out of box B and into my server. The sound was noticeably better right away. Wow! This is an effective tweak. I did an A/B comparison with a couple of CDs to streaming 44.1/16 and I could no longer discern a difference. I was rocking for a few hours until the music stopped suddenly. Box B appears to be defective. The TX indicator light went out on both boxes indicating fiber failure. I did some troubleshooting and using my cellphone camera I can see a red light in the port of box A but no red light in box B. My fiber cable appears to be fine. I noticed after repacking these items that the seals were already broken on the ESD bags. I didn’t catch that when I took them out of the box. What’s up with Amazon these days?

Thanks for this update,
I had a tech geek here in new orleans that **swore** I should dump cdp's and go Stream,
**Its soooo much better resolution**, I  just shuged it off.
Yesterday arrived the chinese 
~LKS Class A/JFET descrete opamps,~~
a  pair of duals @ $50/each , just to try them out,
I  immediaely order a  2nd pair, as the Jadis JS2/Mark2 takes 4 duals. 
I had a  pair of USA made duals and a  pair of chinese high tech descrete duals. 
These new JFET( not sure what this means, but they are really cool looking, even Richard Gray  was impressed = which is a surprise, as his stance is TI makes the best, due to huge lab team/superior engineers), 
WEll let me say just pop in a  single SA100  Descrete or these Dual JFET's, and your player will out shoot any newest DAC or Stream. 
Douk Audio sells duals and  singles  SA200/duals, and SA100/singles.
I passed up Douk and bought another model, the LKS Class A JFET.
Not sure which is superir, my guess is  both are close in performance,  but I think these LKS JFET's are the best bang for opamps.

I received my replacement optical converters today.  It appears the problem may have been in the fiber optic cable.  The old cable does not work at all.  The replacement cable works but one connector is a bit flaky. I had to manipulate the connector going into one converter box to make the connection.  An hour or so later the connection dropped and I had to reinsert the fiber cable.  I need a better solution for the fiber- perhaps I'll try multimode.  Perhaps those connectors are more robust.  Sound is excellent.  I have a CD transport that upsamples to DSD and sends the signal to the DAC via 3 BNC cables.  This Transport/DAC combo works very well with more resolution and a larger 3D soundstage than I ever thought possible with CDs.  So now, I played a CD back to back with streaming 44/1/16k again.  They are very very close.  Next I plan to fire up my analog rig and compare it to streaming.  I almost don't want to know.  Right now, my analog rig has a slight edge over CD with some records.  I guess I will not be able to post my comparison of streaming to vinyl here since this post is titled CD vs Streaming.  What an exciting time for audio.

Of course you can post it up, I’ve done the comparison, and yes while analog is good, it’s maximum of 30db channel separation at 1khz and falls off to almost 10db (mono) in the bass, and around 15db in the highs, it can’t match the 120db channel separation of CD top to bottom.
The sound stage imagining and depth perspective with CD because of that channel separation, is sooo much more precise, wider, and has far better imaging on the outside the speakers too when it’s called for when "anti phase" notes have been deliberately recorded to put them there.

I know all the technical data and comparison between vinyl and analog.  Similar to the SS and Tube amp discussions in the 1980s, SS amps looked great on paper with their great S/N and low distortion but tubes still had the advantage in listening.  With my previous CD player, which was quite good, vinyl still had a clear lead in sound.  With this new DAC/Transport combo and music server I see quite a bit of overlap between Digital songs and records.  Hi res files have the holographic imaging of vinyl w/o the noise so hi res is tops to me now but some records still beat out CD to me with a larger stage and more body to the voices and instruments.  A lot of CDs, and this is not the player's fault since this is not always the case now, make the voices and instruments seem like cardboard cutouts.  I grew up on records, so I can tolerate some background noise in the music.  In fact, for a long time CD was too clean sounding if you get what I mean.  Better turntables and cartridges eliminate a lot of groove noise too.  Speed control of turntable platters is also critical to compete with digital, I think.  Overall, it takes more dollars, more effort and perseverance to get vinyl to a level to compete with good digital.
