CD Quality Versus Streaming Quality

adameos

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!

Why dont you just send him a Private Message to begin with??

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 

I sold my reference quality cd player 15 years ago because ripped music sounded better using 3rd party software like Pure Music. I still have a Sony $1500 SACD/cd player that I have used maybe 5 times in the last 10 years. With high res files and mqa, I sold my $15k turntable and all my vinyl and have never regretted it. 
Looking at some of these posts, they are using cheap stuff like blue jean cables or $100 audioquest cables, like those are high quality. My old usb cable when I used to own that flawed interface was close to $1000. 
The reader software you use makes all the difference for playback quality. If you use Apple’s iTunes/music software, anything will sound better. But if you use Audirvana or Roon, your playback quality goes way up.

Also, when you use a cd player, are you using toslink or coax outputs into an external dac? If so, those are the worst out[uts to use but not as bad as usb, so you already compromised your sound. Or if you use the single ended or balanced outputs, then you are really compromising the sound quality because you are using the internal dac inside the cd player. I have never heard a cd players internal dac sound any good (same goes for dacs built into integrated amps) compared to a standalone quality dac, like the Briscati, DCS, or PS Audio standalone dacs.

My experience has been that streaming great sound but takes much effort. It took me over 1 1/2 years to get the sound of streaming to match my CD Transport and Vinyl sources. Neither I nor my two sons hear a difference now switching between CD or streamer at 44.1/16. Hi res sounds even better but generalizations do not work well with audio. For example, the best sounding vinyl still competes well with the best hi-res audio files. But some hi-res audio sounds the same as 44.1/16 files and some CDs sound better than their vinyl counterparts. Only keep in mind that different pressings of the same vinyl can sound better too.

One of the good, or bad things about this hobby called audio is that we need contrasts to know if one sound is better than the other. Our ears adjust to the sound of our system and we have to hear another system, source or live music outdoors, in a club or in a hall to determine if our system is better/worse. The same goes for sources. So I started out with my CD Transport/DAC combo which sounds great to me compared to other systems I have heard as well as my vinyl source. I bought a music server/streamer and ripped my CDs to FLAC files and got a subscription to Roon. It took a little work finding the right USB cable to get FLAC files and CD to be indistinguishable. At that point streaming was good but not up to CD or FLAC files. After going through various configurations, cables, power supplies, FMC’s, different SFPs and so on I got to a final configuration that makes streaming equivalent to CD, FLAC and downloaded hi-res files.

I am not saying this is the only way. I’m sharing my configuration to help others save time/money.

1) Ditch the ISP’s modem. Get a good quality modem. I also added a low noise power supply to the modem and router. Can’t say that I would hear the difference in an A/B comparison but it is a relatively low cost upgrade. I have coax cable internet service.

2) Get a good quality router. Ethernet cabling is a must for good streaming but a good wifi router should do no harm to the network signal.

3) Get a good audio grade network switch. I struggled with the idea of spending thousands on a network switch. When the LHY SW-8 came out I grabbed one and love it. Very effective. Until then I was using a fiber optic link between my router and streamer. It is good; but the SW-8 is better. Now, the thinking would be that two good things together would be even better. Wasn’t the case. The SW-8 performs best direct into the router.

4) Use Ag plated ethernet cables. Full silver might be better- I don’t know. Silver plated cabling makes a difference. Well worth the minor investment.

I’m sure others have different experiences. Many paths to the same goal. Everything matters. Also, my SW-8 is plugged into my power conditioner.
