Keep that Thorens running PetterS. It can really play jazzzzzzzzzzz................. :-) To be serious: I hear it exactly as you do PetterS. I find your contribution here to be in line with my perception of the problems digitally reproduced music run into. The problems that analog recorded music ru...

Wow, I still don't get it. I understand that data being transferred is always clocked. This is fundamental to the transfer of digital information. But this is a different time domain from the audio processing. Do we need to worry about anything before the last time the data was "at rest"? (and if w...

I find that static data is relatively stable and exact. I say relatively, because there are some really strange things that can happen when storing still bit perfect musical data, but these effects are minor, so let's ignore them for the moment. The source in a digital replay system is where the da...

I almost feel a bit guilty driving the hype train, but I can only say what it felt like listening to it. It didn't feel like an incremental improvement, it felt fundamental. I have no idea how or why. Amusingly, I mostly played vinyl through it, which also means streaming source and network setup is...

Ok, so I've finally heard it. I was at Tonläget Hifi today, for a tuneup of my LP12. I got to hear the Klimax 350 Exakt (Katalyst) system with the new Klimax DSM Organik used as Exakt hub with a full spec LP12 connected via Exakt. It sounded great. Tight. Fluid. Tuneful. I would love to have this sy...

Ok.. I actually have one myself. Not an "explanation", but at least an actual difference between DHCP and fixed IP: There needs to be something on the system to keep track of the lease time and trigger a new negotiation. Older Linux distributions (which is what I assume the Tinkerboard part of Käll...

Yes, that is how it's supposed to work. Still, assigning Källa with a fixed IP address instead of DHCP removes a small but easily heard "digital signature" in the music. Not once every 12 hours but all the time. Do you have any explanation for how this can possibly be? It seems to defy understandin...

Taking the hifi part of the network out of the DHCP range reduces the tireless pinging that goes on with constant address allocation and confirmation. A noisy process. Fixing addresses also helps. Helps what? And how? DHCP: Client: Can anyone give me an IP address? Server: Sure, I can. Client: Cool...

IIUC, Apple and Airplay capable.

Matt

Or just Airplay capable, reasonably.

If that’s the case, what happens if Apple releases a new OS that prevents unlicensed users from accessing Airplay? As I understand it, it would be technically impossible without also dropping compatibility with all the Airport Express devices that have the exposed private key in their firmware. But...

Streaming is obviously the future. Yes, this is hard to argue against. Personally, I play vinyl or stream. My thousands of ripped CDs on the NAS almost never get a spin these days. But the downside to streaming only is obvious. Music that used to be available on your service disappears (several hig...

A little summary is that the Källa is a single box streamer/DAC that uses the proprietary Lejonklou Protokoll for sending the music to it that requires an Apple device. This is rather strangely put, and, I suspect, borders on the incorrect. Until Fredrik (or someone else who knows) sets the record ...

I would expect any device that can access files on a NAS and output sound via AirPlay to work for this usecase. Maybe Apple doesn't want your phone to be able to do it, but surely a regular macbook or similar device would?

One less Apple. I, for one, am never going to buy one, if I can avoid it. The Qobuz app is not Apple too. Matt No.. I might have jumped to conclusions here. I assumed the Qobus app to only be able to do AirPlay on an Apple device, but that Audinirvana, apparently being a cross platform solution (I'...

Also, and I really hope I’m right here, I’ve read that the Qobuz app will act as a control point for AirPlay enabled devices. That would make the Käla control point almost as good as Roon, but for free! I just confirmed with Damien, the developer of Audirvana, that Audirvana can output Qobuz via Ai...

Normal Redbook CD albums are disappearing from Tidal. What remains are "MQA" 44.1 (16 bit) albums. Very sad. Matt My reply is a bit late but there's a very informative video about it here Yeah, I saw that one earlier today. It was the final push I needed to end my Tidal subscription. More and more ...

why I said what I said is the following quote from Fredrik which I had in my memory: „I have the AK4497 but haven't heard the 4499. Even better sounds promising. There are also some other new chips around and then there's R2R DACs, which require an extreme amount of precision in the resistors, but ...

You'd be surprised how many different mixes there can be of a piece of music. I once heard a radio program that delved into this. I think the group involved was REM but I could be wrong. The program was about the different mixes that are made of a song and how sometimes people buy an album based on...

Sounds great :-) Will it allow streaming from Qobuz and Spotify? What is the interface for connecting a DAC? Thanks Matt why do you think you need to connect a dac? my guess is we might see a resistor ladder dac as thats what Fredrik is really good at - selecting the right components to an incredib...

I just get more questions. :D

I'll leave it alone for now. I'm sure there will be more information coming..

(Though it does sound like all that is really needed is a device that can speak the correct protocol. Perhaps something like OwnTone would work...?)

And you'll need an Apple device. Wait, what!? What could possibly create this requirement.. are you using AirPlay? That doesn't seem at all likely, but I'm wracking my brain trying to come up with any other explanation.. unless it's simply that the control interface is only realized as a Apple app....

I agree. When talking about one specific comparison, this would be the simplest explanation. Certainly one to rule out before reaching for the "unexplained".

Yes, the 1s and 0s are all the same, some like to call the process "lossless" because of this, but the music is changed. It appears at this point that we just don't know enough about all the factors involved in the music recreated at the end of the chain to measure some of the important things invo...
