Request for support of Spotify Lossless[Resolved in v1.5.60, support Spotify connect lossless/24bit]

No.

 

I think folks experience is that some files are 16 and some 24 on native, built everything shows as 24 on eversolo currently. I’ve heard arguments about whether there is actually any data above 16 in 24 files, but I’ll leave that for others to argue about. Note that a CD has 16.

 

My A8 preamp(set to rk3566) Spotify connect is working in both 24 and 16bit. I don't actually know if the files are in fact are being reproduced in this bit state.

If a file is 24bit it does show up as this in rk3566 but generally most are 16bit currently and will remain so for some time anyway.

Using DMP-A8 setting it only shows 16bit files for all files. As Eversolo support says it will only play 16bit at this point in time.

Where the rk3566 comes from is beyond me. I have updated A8 to 1.15.45 v. and Spotify did update on 15th December.

I guess it will all work out in the end. I'm in New Zealand so whether these make a difference to others in other countries is also beyond me.

 

Are you seeing 24 using Spotify connect lossless, or the internal Spotify app? If its connect, that would be new (and good) news. Note that CD quality is 16. Most music files are 16. Many that claim 24 have been up sampled anyway. The percentage that are true 24 is relatively small I believe.

 

I can see 24 bit on both connect and internal app. But in the internal app it shows as This phone but as rk3566. I updated the internal Spotify app and the connection showed as "This Phone". Which I think exists in the A8 as its not in my Samsung Tab remote. Have to say the whole thing has been a challenge and hard to understand.

 

Yes, I agree!

I believe when using the internal app, it was treating the eversolo as a phone, and the rk3566 might be a chip designation or some such. If you stared with the internal app and started playing a 24 file, and then launched connect, it would continue to show 24, but still show it was connected to rk3566.
If what you are now seeing is that you can start with Spotify connect to eversolo whatever, and it sometimes shows 24 without having first started in the internal app, that would be new and a good thing. Maybe Spotify has flipped another switch on their server side.

I do think the whole 16 vs 24 thing is a bit of a red herring. I believe there is really very little music that is natively 24, but maybe things have moved on and I’m wrong. When you play a CD, it is generally 16.

 

The RK3566 is a System-on-a-Chip (SoC) - Rockchip , and it is used in your Eversolo (ARM-Cortex A55 which transports the digital audio to the DAC)

 

Thanks. It is good to know the specifics.

I tested 24 again using Spotify connect. For me, it is still playing at 16, unless I start with the internal app. It’s possible they are rolling out 24 in groups, or something else is going on.

I would point out that 24 is not all that common on Spotify. Most tracks are natively 16, which makes sense. I had to do a search on “audiophile 24”and then you get a list, but even then some of the tracks on the list were 16.

 

I agree I tried today and I had to do the same process. Once its set it stays in place for the day.

 

Thanks. In retrospect I’m not even sure how much 24 Spotify has. When I play Qobuz, it just says hi def. It does not say 16 or 24. Who knows

 

When I had Qobuz it showed 24 or 16. I've dropped Tidal and Qobuz now. I prefer Spotify for finding new music for my tastes and its sounds better in lossless. The differences are marginal but always thought Qobuz was the best. What we are actually getting is beyond our control. The only certain way is to use downloads or ripped files.

 

That’s interesting. On the iPhone app I was unable to find where it showed 16 or 24. It did however show me sample rate.

 

I'd be curious to measure your bit depth when you listen at home, you'd be amazed, and maybe you'd stop this paranoia.

 

Ha! I was just asking how I see bit rate when I’m playing Qobuz. I’m not seeing it as a metric on my iphone. It just says “up to 24 bit” which is the same thing it says on Spotify, but we then see that it is playing at 16 bit on another screen.

I now see that on the eversolo screen, using Qobuz connect, that it says 24bit when playing.

 

I agree. I’ve also noticed that Qobuz plays a bit louder, which makes it harder to assess whether I can really tell the difference between 14 bit on Qobuz, and 16 bit on Spotify for the same song, since I then have to level set, which makes quick blind testing challenging. I’ve settled on Spotify as well.

 

Yeah Qobuz definitely plays louder . Im guessing it you volume level match you would not be able to tell the difference .

 

No. If you see the pics, it is the SAME song, same source, 24bits on Marantz and 16bits on Eversolo

 

Here is what the designer of MHDT Laboratory’s Orchid Dac (td1541A r2r dac chip) told me regarding 16bit vs 24bit in 2020.
“Also, the 16 bits is MSB (most significant bits) of digital stream.
It means that 16bits out of 24 is not mean 2/3 of entire stream but is about 96-99% of entire stream. In the days of the study of Philip/Sony s' engineers said that 16 MSB is already the max hearable of human's ears”. I don’t have the technical know how to know if that relates specifically to that chip.
