You need to subscribe to MyVolumio, login and then you can login to Tidal and Qobuz directly from My Music.
I have Spotify Family too, it's excellent value for money.

Still nothing back from Allo to my support request sent on the 31st Dec.
Must have got lost over New Year.. New request / reminder sent.
I've not had any responses on the Audiophile Style site they say is their centralised support place either..
Here's hoping.

Best check the sites that tell you how to spot a fake, that sellers feedback is only 90% so be wary. If buying from Amazon for instance ONLY buy the ones sold by Amazon NOT a market seller as they will more times than not be fake. |

I ditched the 1.5TB Samsung usb drive with 950 artists and multiple albums..
Volumio handled it well but a flash drive with just the ones I can't find on Spotify, was worth a try I thought.
Of course with so little on it, it's lightning fast.
Will evaluate sound later on today.

Indeed - it is absolutely NOT worth skimping on SD cards bearing in mind their application. Buy a good brand from an upstanding vendor.
Apologies to Steve for hijacking his thread.

Are you using the RPi's USB socket (not great for SQ) or a NAS or Windows share? |

Yup - should be good. My only caveat is that USB implementation in routers is pretty awful and only USB 2.0 usually.

Yes. It definitely sounds better, cleaner, more dynamic. Getting rid of a powered spinny data data retrieval device for solid state memory is an improvement. Nice of Talktalk to give a little schematic   16GB will go quite a long way for Spotify missers -) I need to up the Spotify streaming game now. Only a few things left to do.. |

This evening's fun was to strip out the RPi / Kali and install it properly, bolted in, although that makes access to the SD card a bit tougher!
The short I2S connecting wires won't like being disturbed so bolted down was necessary.
As ever, check and recheck polarities and pin connections.
Nice when it all works first time..

Yes, I thought you would install it properly. Nice work getting it all going!
Did you present the Pi to the rear of the chassis or bring the ethernet cable inside?

The need for < 40mm connections meant the RPi / Kali has to sit Infront of the Najda board. So the Lan cable and power has to find its way to there. Reminds me of a question I have.. what do you call a Lan chassis mounted socket that has a short lead to a plug? - I don't know, what do you call a ... Boom boom  Seriously, I'm trying to order one and my searches aren't returning anything of use. I want to have a Lan socket on the back of my Najda case that leads to the RPi. And I don't want to have to make it up.. You can easily find / buy similar such things for usb chassis mount sockets to plugs.. Next up is copper casing some things inside the Najda case.. |

Something like this? Easy enough to snip a short patch cable and punch in at the chassis socket end.  |

Yes that looks good Martin, I might just go the continuous Lan cable approach and have a grommeted cable width slot at the top of my Najda case. This actually appeals to my prototype, nothing needs to get too prissy or permanent approach. I must be on version 5.5.35 of my system by now Good news! Allo support got back to me. They recommended setting the DAC model to R-PI DAC in Volumio. I just never got that far down the exhaustive list This I did, and it did not crash the RPi or brick the SD card Good start! Also they said: "With Kali 24bit format does not play back properely. So enable Audio resampling on to 32bit." I did this too and just had a little listen. Sounds good! Instrument placement and timing is as it should be on all my test tracks. The very slight overall balance offset, still there on Apple Pi DAC, is now gone. As Martin pointed out earlier the Audio resampling setting does not affect Spotify etc. It did change things on NAS file playback. The lights on Kali change accordingly. I set the target sample rate to 96, as that is what Najda works at. I have yet to try other settings. Most of the time I'm using Spotify anyway.. I re-asked Allo support if there is any other way of connecting Kali, using the MCLK etc, but I suspect I have it as it should be. |

I think your Najda generates its own master clock as otherwise the I2S connection wouldn't work. This is also true of the LKS DAC I'm considering - no MCLK input signal required over I2S as it generates its local master clock from the femto-clock.
That brings me to a future possible upgrade for you, depending on what clock the Najda uses. If it's a standard crystal you might be able to install a Tentlabs or similar superclock for lower jitter. It made a hell of a difference to my SEG.

I'll have a good search on the Najda DIYaudio thread. I'm sure it's been discussed. If not I'll ask Najda Nick |

Hehe,
From the horse's mouth a few years ago
"I2S buses are currently clocked by the codec chip.
In order to gain a good understanding of the clocking, you should look at the datasheet of that chip (CS42428).
The basic idea is that the DSP generates a base FS clock (so 48 kHz at 48 kHz sampling rate, 96 kHz at 96 kHz sampling rate etc). This FS clock is fed into the codec PLL, which on its turn derives all required clocks to sample the audio and drive the I2S buses.
As discussed previously with MellowFellow, I don't think there's much benefit in replacing the DSP crystal. On the other hand, the new firmware will activate the external clock input, and this will allow short-cutting the PLL."
And
"The I2S bus consists in audio lines and in clock lines.
The device generating the clocks is the bus master.
In the Najda, the CS42428 is generating those clocks - i.e. "I2S buses are clocked by the codec chip" - all buses except the I2S input (which is clocked by the master I2S source). So for the SPDIF outputs, the audio samples are coming from the DSP of course, but the clocks are still the ones from the codec.
As for your other question, it's still early to give specs for the external clock. We'll talk about that soon again."
I smiled coming across comments where one guy compared Najda to a +£5K DAC and Najda was better..

I've not researched these things. Is that good or bad? |
