No, Spotify HQ is 320kbps using Ogg coding. To my ears, it's virtually indistinguishable from 16/44 red book standard.

The 24/96 upsampling in Volumio is for files only, it won't affect Spotify.

I have a slight preference for files over Spotify but it very slight. The Signature is a different beast compared to the DigiOne a good step up in resolution it is a bit more clinical at present but still might be burning in

I wonder how close my split power supplies (modded DigiOne) gets to the Signature?

I'd love you to, John, as it'll help me to decide whether to go for the upgrade.
Meanwhile, I'll be working on the SEG some more.

I have a slight preference for files over Spotify but it very slight. This statement would concern me, as locally stored equal quality files will always sound better no matter how good the stream currently. I cannot replicate this effect on any platform I use either streamer (three different makes) or my own streamer Martin One for you I feel.

It depends on what files, Tony. Let's stick with red book 16/44 files for comparison. In terms of streaming, I find Qobuz HiFi virtually indistinguishable from Spotify HQ, which says a lot about how efficient lossy 320k Ogg is versus lossless FLAC. There is only one track I have found so far where the Qobuz sounds slightly more dynamic, but it's by a whisker only.
If I then compare with local files, again I find them to be very close indeed in quality. In my listening it's classical music that benefits more from 16/44 than other types of music, but not reliably. I would put this down to the greater complexity and dynamic range of classical over modern music.
ALL of them sound extraordinarily good, and better than CDs played on my very competent Ayre SACD player. This tells me that the Pi/DigiOne/SEG/PSU combo are performing at a very high level, rather than bringing everything down to the lowest common denominator. I remain, therefore, thoroughly and jaw-droppingly impressed with what Spotify HQ can achieve.
Having been through every component change in a similar way to John, I can tell you that the DigiOne is largely responsible for the incredible leap in sonics. Let no-one tell me that low jitter reclocking and ultimate attention to timing doesn't matter in digital replay. It's highly critical.
John and I are now taking slightly divergent steps to see what works best, or whether they work in harmony. John has the DigiOne Signature while I'm about to install a TentLabs superclock into the SEG. We will compare them and try to identify what each does, if possible. One thing is for certain: these mods are worth doing as they cost peanuts in real terms compared with a major component upgrade.

Hi Martin Still not buying I'm afraid; as I am comparing red book ripped and downloaded 16/44.1Khz files directly and against Spotfiy premium and Qoboz and the difference is clearly audible no problem at all. A couple of times in the last few months I have seen "oh streamed spotify is better than files (equal bit/sample rate)" on a few open forums yet have not actually listened to this on ANY streaming device whether commercial or DIY home brew (some of which are pretty Good!) Having maxed out a SEG with fetmo clocks, extra supplies (4 rail psu like your one) for the ultra reg's which now feed the 3.3Vdc and the 5Vdc rails it still doesn't come close to whats possible, but agree it makes a good difference and for the outlay is a worth while upgrade no question at all. Though that SEG had to go into a bigger box which took some effort I can tell you! There are three clocks in the SEG, depending on whether you use USB or SPDIF, the dac and the other clock is for the PIC. I am willing to be genuinely convinced so if you and John would like to pop round and show me I am barking up the wrong tree I am more than willing to be genuinely converted Either I am missing a fundamental trick here (which is entirely possible and has been known once or twice!) or there is another reason? Happy to put on some food and drink and clear a day and let you guys have run of the equipment, you set up the equipment the way you want to, no strings. Tony

I recently bought a NovaFidelity X40 streamer, and I have found the following.
- Red book CD files I have imported into my Mac using iTunes as Applelossless and then stream into the X40 are about the same as Spotify, marginally worse possibly
- Red book CD files I have imported into my Mac using dBpoweramp as FLAC and then stream into the X40 are marginally ahead of Spotify.
- Red book CD files I have imported into the X40 directly and stored on its internal drive are in a completely different league altogether, so much better in every way.
I went for the X40, because in the context of my system, playing files imported directly onto its drive, it was better than my previous CXC Transport and modded SEG by quite a large margin, and the Pi I had, wasn’t as good as the CXC, again in the context of my system.

Quite happy to do this well John no problem as it also gives me first hand experience of what you are hearing.
Just remind me of the rest of your system please

Almost baffless speakers inuke for bass Philips Black Tulip for the full range PRV drivers and of course the SEG It's not very conventual I admit Certainly not high end but might surprise you what it is capable of

Has anyone tried comparing Spotify via the Pi with any other methods of delivery?

I used to try it with my fanless W10 I could not seriously listen to it. The difference was huge
