The Teclast has LDAC and a 10.1" screen.

Thanks Jules Will ponder The main criteria has been more than answered with all the sampling I'm doing. Can see pros and cons in another piece of tech. Be interested to hear of the pros

Being able to open YouTube on the laptop and play through the system without Volumio or similar getting in the way is perfect. A point I hadn't thought about is letting YouTUbe choose the next item for me and discovering interesting music from artists I know and don't know
Radio 2021 style

I don't quite get this, Youtube resolution for music is poor if you have it set to Low to minimise bandwidth impact its 48kbps, medium is 128kbps and max is 256kbps, however you look at this is compressed lossy and poor MP3. The only reason I can see using youtube as I have occasionally is to see videos of musicians and explore some music, but most that I want is on Qobuz, Tidal or Spotify.
Personally if cost of a subscription to Tidal or Qobuz was an issue then I would just use Spotify, which is free and I believe streams at 320kbps so even though still lossy MP3 level its the best you can get of this.
I presume from what you are saying Mike you are going to plug your computer straight into a DAC using USB to stream music, connected to your amplifier, in which case you just need to download the App for the service you want to use, Spotify, Tidal or Qobuz, in this instance you would not need Volumio.
If you wanted to control it from a mobile phone or tablet, you would need to install Volumio onto the mobile device, sign up to Volumio to enable you to use the service (Spotify, Tidal, Qobuz).
If you were not bothered about that then, if you had Volumio running on your RaspberyPi then you could just download the Spotify, Tidal, Qobuz apps onto the mobile device and then point the Wifi for the app to Volumio for sound, on an Apple device this is called Airplay. When you used the app on the mobile device it would process the music and stream it to Volumio on the RaspberryPi and then to your hifi system.
I hope this has not confused matters for you.

You would be surprised how good YouTube can be I have friends who have really good systems and YouTube via Bluetooth is their go to service. They have all done the streaming with gear that a lot more expensive. I think YouTube just has a bad rep as most people have not tried it via BT5 and LDAC or APX HD

Thanks Adrian I wanted to run my laptop into the system via Bluetooth, no cables Chrome with Allmusic, Amazon and YouTube. Occasionally Spotty. Previously used laptop / Volumio / Pi. Not happy with the results and confirmed I wanted to stay with CD for serious listening. Someone somewhere has been able to run their computers via the Pi into their system. That seemed beyond me When I want to improve sound quality my upgrade path seems to be a tablet and PSU No rush for that ATM

There's certainly a big difference in quality between free Spotify and Premium.
I don't really care that Premium isn't 'high res' - it sounds great, but I will trial their new 'HiFi' service when it's eventually released

Spotify Mobile is 96kbps, Free is 160kbps and Premium is 320kbps.

No it isn't, the CODEC is Ogg Vorbis which sounds a lot better than mp3, so Ogg at 320kbps is why Spotify sounds so relatively good. It may do but "The desktop app’s standard quality is Ogg Vorbis 160kbit/s. Premium subscribers can choose to switch on High quality streaming, which uses 320kbit/s" I believe it drops to 96kbit/s on a mobile device. This is what I found on the Spotify support site. OGG Vorbis is Lossy, so SQ is depleted anyway from the original, my understanding of OGG Vorbis as reported it is an improvement over MP3(my mistake above saying MP3 was used by spotify). OGG Vorbis is primarily sighted as being an improvement with respect to using less storage than other CODECs with respect to compression. Presumably the key reason Spotify do this is to save on bandwidth with their infrastructure. Something else I am aware of but do not have a clear understanding of yet, is that if you stream/cast to another device from Spotify then if that platform does not support OGG Vorbis then this will cause re-encoding into a supported format, say AAC or MP3, this is likely to result in further degradation in SQ.

Interesting - that could be another explanation for why Spotify sounded superior on headphones on Mac compared to my phone.

It is interesting the different experiences and thoughts on this. For me BT5 using either Spotify or YouTube is preferable to any of the servers or super spec computers I had in my system. Trust me I have had quite a few. These days I am heavily reclocking and no desire to go back to the hassle of streamers. It would be great for others to hear what I am doing but times are different now.

I have a theory about 'air gapping' in order to reduce noise transmission through the digital chain.
I do it with a 4G router, you do it with Bluetooth.
Both seem to work extremely well.

Yes for me I think a lot of my issues was the ethernet chain even though I was using a Melcord and Acoustic Lan Revie it was the weakest link and believe the main problem You have found a great solution to this with those high grade clocks you have

So lets say I compare the BT5 with the Limetree Network player. The Limetree has a touch more detail but it also has a edge to the sound and believe this was mainly due to the ethernet chain.

That is such a tricky problem to reduce, I have paid more attention to that than anything else in my system.

Post by John on Jul 13, 2021 7:31:22 GMT
Agree I prefer to miss a touch of resolution than have the edge. What put me off your route was all the extra cabling and costs. I stumbled into a solution that works for me. However I do admire the effort you put into resolving this.
