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 https://dr.loudness-war.info/
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.

Compression? How about cd vs vinyl.


If you look at the dynamic range data base https://dr.loudness-war.info/, vinyl has the better DR figures also, just like the early versions of older cd issues before they get compressed.

Where cd kills vinyl is in the channel separation, with vinyl you’ve got at best 30db of channel separation and that’s at 1khz at 16khz and at 50hz it’s much worse, almost mono. Where with cd you have 120db channel separation right across the audio band 20hz to 20khz

Why don't you just set up a blind listening test and find out if you can pick out the best sounding one.

I've only been streaming for a few weeks but noticed that Qobuz - hi-rez included, has fairly substantial compression applied.  I witnessed this on pretty much everything I have listened to.  It sounds fine at lower volume levels.  But turn it up and... ack.  For fun, I ripped a song off of Rumours (24/192) and it proved exactly what I was hearing.  It's like an average level was established and nothing escapes it.  Not rim shots, cymbal accents, screams, explosions, nothing.  After ripping hundreds upon hundreds of LPs, I have never seen a cymbal get struck and fail to move the level meter at all.  It's....very odd.

Now you know why I’m so anti compression, and started this thread and even more this one
" Stop compressing our bloody music!!!!!!!!!!! " https://forum.audiogon.com/discussions/stop-compressing-our-bloody-music?highlight=stop%2Bcompressin...
No sounds in life are compressed, why do it to our music, and force us to listen to it

@georgehifi it's disappointing because the potential was there. Kind of like Sat Radio. Such a great concept but a complete failure in execution. I was all set to pay for a year of Qobuz after my 30 day trial but now I really need to weigh all options. Or maybe just pay for ROON and rip the rest of my CDs and LPS to a NAS.
