Although the primary focus of Källa is streaming services, it can also play FLAC from a NAS using an app like VLC.

That's good news as I have close to 4 TB of music on my NAS.

Thanks Fredrik, looks like I need to read all the information about Källa.

Hello,
A quick question about the Sagatuns and the mute state. If the preamps is in mute, not lowered by 12db, does the LEDs keeps flashing? Is that correct?

Hello Hermann!

Yes, in both the -12 dB and the full mute state, the volume indicator keeps flashing.

Thanks Fredrik, it's different from what I'm used to.

When will the Kölla be available? It looks like it would be suitable to replace my NDS.

Yes, I see. The decision to keep it blinking was made because if it would go dark, there is no way to know whether the unit is muted. And if you listened very loud, it would then return to that high volume once you pressed MUTE or VOL+. With the blinking you can see which level it will return to by the colour in which it blinks.

Källa will start shipping any day now. But as I need to check every unit carefully before it's approved, it will take a while until the preorders have shipped. Stay tuned!

Thank you Fredrik for the explanation. As soon as a conventional potentiometer is used, the volume setting can of course be seen directly. In this respect, I can understand the decision. It just takes some getting used to.

Obviously the following passage from the manual is translated incorrectly. I actually assumed it went out and the Sagatuns had an error.
  • Pressing and holding MUTE for half a second (until
    the indicator fades) mutes the volume completely.
    Volume is restored by pressing MUTE or a VOL button.
"Fades" translates to goes out, actually as I understood. Mh...

I would have no problem with the LED lighting up during mute, as it is switched off during "operation". Flashing lights demand attention and can be distracting, certainly depending on the location of Sagatuns. On the other hand, the flashing indicator at -12 db is appropriate, as the condition is usually temporary.

We've had power cut twice in the past few years and I was'nt at home both times. The Naim preamplifier automatically starts in mute mode. Have you ever played through the scenario of a power failure? Is there anything to worry about if Sagatuns not muted?

My enquiry regarding Källa is placed with Marco. I am very curious about this test, especially since the NDS seems to have taken my thoughts on board and shows a musicality that is stunning. After a small change in the line-up, it was immediately clear that he was playing sub-optimally before.

It's much easier to try and see in real life how the volume works than to explain it in words.

Actually the quoted passage is correct. What happens the instance that you push a button on the remote is that the indicator lights up. Then, if it's the MUTE button you're pressing, Sagatun will count how long before you release it.

If you release the button while the indicator is still on (within half a second), Sagatun will go into the -12 dB state.

If you keep the button pressed until the indicator fades out (more than half a second), Sagatun will go into the MUTE state.

The indicator will then start blinking; mostly on in the -12 dB state and on/off in the MUTE state.

If the power cuts, or you switch Sagatun off and back on, it will always start at volume 40 (blue). The original plan was that it would remember its last volume setting, but it turned out that the contents of the internal memory significantly affected musicality - even though the circuit was in its lowest power (sleep) mode and the digital section was isolated from the analogue path. This was one of the first times that I was completely dumbfounded by a technological finding. Many more were to follow when the work on Källa began in 2017.

Thank you for taking the time to explain Fredrik. I'm sorry I couldn't follow it, but understand better now.
