CD Quality Versus Streaming Quality

I realize this will be a contentious subject, and far be it from me to challenge any of the many expert opinions on this forum, but if I may offer my feedback vis-a-vis what I am hearing, and gain some knowledge in the process.

i will begin saying that my digital front end setup is not state of the art, but i have had the good fortune to listen to a number of really high-end systems. I guess the number one deficit in my digital front end is a streamer server, and no question about it that will improve the sound.

My CD player is a universal player; Pioneer BDP-09fd. It uses Wolfson DACs. It has been modified to a degree. I have bought and sold other players, but kept this one, because it has a beautiful sound that serves the music well.

Recently, i ventured over to my son’s place and we hooked up my player (he doesn’t have one and rely’s on streaming only) We compared tracks / albums of CD quality and master quality streamed on Tidal with ‘redbook’ CDs I have. For example, some Lee Ritenaur CDs and some Indian classical and the wonderful Mozart and Chopin.
His system is highly resolving.

we were both very surprised to find the CDs played on the player to be the better sound. And not just by a little. The sound was clearly superior, with higher resolution and definition, spatial ques, much better and clearer imaging. Very surprising indeed. Shouldn’t there be no difference? This would suggest the streaming service is throttling the bandwidth or compressing the signal?

i am most interested to hear others’ observations, and suggestions as to why this might be? I do love the convenience aspect of streaming, but it IS expensive for a chap like me of fairly modest means. The Tidal HiFi topline service is $30 per month I believe, something the good lady is not too thrilled about. God forbid I should suggest Roon on top of that I may likely get my walking papers. I jest, but only partially LoL. My point is, if I pay this sort of money, isn’t it fair to expect sound to equal the digital stream from the CD player and silver disc?
Thoughts?

Hi Jafant,

I bought the player from a serious enthusiast. He had modded the player to include some form of vibration damping, dynamat treatment and fuses. I believe he did something with the power supply. I am not quite sure, but i have compared this BDP-09fd player side by side to two other BDP-09fd players. The improvements are immediately obvious and compelling. The most general way I can describe it is a more musical presentation. With this modded player, the center image is certainly more present and clear while the sound presents as ‘bigger’, without losing focus. I also perceive better rhythmic drive / better timing. That might be the result of eliminating the smearing associated with noise.

Thank You for the follow up. The BDP-09 is still a Reference Player. Sad, that Pioneer does not support these Vintage products. If you find out more specifics about the "mods", contact me.

What other gear is in your System?

Happy Listening!

I recently picked up the BDP-09 for my collection and system. Do you have any more information regarding "Mods" performed on your player?  Feel free to PM me if you do not wish to divulge here.

 

Happy Listening!

I have reached the same conclusion. I use tidal master streaming the highest tier service they provide and listen to what they call the master tracks. Using the same DAC with my CD player ( ARCAM CDS50) I can tell subtle detail that is more present in the CD, the dynamics are sharper and sound stage is wider. The difference became even more noticeable recently as I upgraded to a pair of KEF R11 Meta floor standers. I check the streaming bit rate and frequency to make sure it is playing FLAC at 48KHz theoretically a higher sample rate than CD but the sounds is inferior. Even non audiophiles can sometimes tell the CD sounds cleaner or nicer or whatever better. 

I think the difference is in mastering or how the album is digitally encoded at first place by the streaming service. I think it is optimized for  most low end and those tiny streaming speakers. When the information is lost during the encoding then play back at higher bit rate will not recover the lost tones. Of course this is just a guess but I have no doubt even the so called Master streaming does not sound as good as a CD for many albums when played back through a Hifi system. It’s great that CD is so cheap these days especially lightly used CDs. I see myself collecting more and more
