Now started using using my QP 1 to power the hub adds a bit more depth to the sound whilst streaming

What in the name of Daisy Duke is a "medical grade" PSU??

Another good reason for supercaps... current capability. Instantaneous - yes. Constant current capability, they make no difference. I must ask Tony what my QP-1 can supply, thought it was around 3A. I didn't intend to dive into the details...the only two full supercap PSUs I have experience of can give 5V @ 4A continuous. Naturally the continuous rating is a feature to the PS used the trickle charger (if 4A can be described as a trickle). Both PSs will power my current hungry DAC (5V 1A) for well over 30 seconds. What I had in mind in my original post was that even a power hungry startup for the Limetree should be very well catered for by such a PS. These (Temple and Ciunas) supercap PSs should be able to manage something like 8A 10 seconds at a guess. The interesting thing with the two SC PS designs is that they are different - SMPS trickle charger vs linear and very different supercaps - yet they sound the same with my DAC. The SC designs out-do my Paul Hynes ps and various batteries.

Yes, my QP-1 dual 5V dual supercap PSU can run my Pi streamer for a good 20-30s after removing power. I use it for dirty (Pi) power and clean (Kali reclocker) power.
I still suspect a grounding issue that prevented the Limetree from initialising. It did show its LEDs, but would not start up properly.

What in the name of Daisy Duke is a "medical grade" PSU?? I suspect they are made to better specs, especially for RFI and EMI around other medical equipment. However, it's probably as misused as 'milspec' and 'laboratory grade' are.

What in the name of Daisy Duke is a "medical grade" PSU?? Medical equipment can be sensitive to RFI, and can give false readings and the like.
The PSUs of equipment in the vicinity are heavily filtered to very much reduce RFI.
And yes, I agree with Martin, medical grade probably is a misused term.

Just a quick update The bass has increased in depth and punch. I now had to move the bass volume down a notch on my Behringer In the past I would of described my sound as a bit lean. Now it has warmth and depth.

So is everything set up to work optimally in the system or are there any further tweaks needed for the streamer?

Good outcome, John. Sounds like it's working well for you.

I still, need to add the PSU to it Jules

A further update I just tried the Tidal interface and it is even worse than Quobus as will not stream for from it just says files not available when you click on the track or album. Also the same awful search facility as Quobuz. Thankfully for files and Spotify no such issues and sounds a lot better than the SOtM Ultra Neo. If Quobus or Tidal is your main source I could not recommend this player. It would work quite well using Tidal and Quobuz if using as a Roon endpoint in that case those issues would not be present but more costly due to extra Roon subscription.

Yes, I did think the Limetree app interface was making things a lot worse for Qobuz than is necessary.
Volumio handles Qobuz a lot better.

Yes the search function is pretty poor in comparison But for me it works as I am not using either and the unit is fuss free to setup

The stock smps is quite fair the key was in the casework 3amps @ 5.2vdc John now has his QP1 powering the lime tree network bridge
Some are arranging of the internals and new regulator and now 5 amps rock steady if required no issues with internet connection sounding rather nice know I believe
One interesting feature the unit has is a sma WLAN input upon an inside inspection I feel a full reference clock can be applied to this little gem which would really take it into quite decent performance
Nice product

The PSU has up performance over the SMPS which was a medical-grade unit. Deeper soundstage, more detail and dynamics. I had to lower volume levels by a few dB to match the volume I am used too. A scary proposition adding a reference clock as already sounding very good and will have to wait until Lindermann get permission from Spotify to add to the app, as at the moment I am using the WILAN input to hear Spotify Tony reckons a bit more to come from the PSU in the next few days

From my understanding the Lindemann "Network Bridge" appears to really be a media player with functionality comparable to a Raspberry Pi with an Allo Digione, except you pay 5 or 6 times the price and you have to make do with the software they provide. Plus you still need to buy a good PSU - as you do with the RPi/DigiOne. Is that correct or am I missing something? How does it sound compared to the RPI/DigiOne combo?

There are two versions. Mine is the Bridge version. The Network Player version uses a built-in DAC but I have a better DAC so did not see the point I cannot make comments on the Player version It is pretty good with the supplied SMPS I had a PSU with 2 outputs and just made sense to have this converted. It was beating my old SOtM Ultra 200 even with the supplied SMPS. The SOtM is considered better than both the Digi One and Signature. I have had them both and think the Limetree beats all 3 in sound quality in every way I can think off. Adding the PSU just takes this further especially with Files The Lindermann does have its faults. Its interface with Tidal and Quobuz is poor in terms of searching, it could be so much friendlier that way. But no issues with Spotify via BlueTooth and Files Please remember to get the best out of the SOtM 200 Ultra Neo it is also highly recommended to use a good PSU

A further observation I took the Lindermann around to a friend who has the Allo Sparky and a fanless pc using HQ player resampling his files to 756 My friend ordered the Limetree as on comparison the pc was two dimensional This was with the supplied SMPS
In terms of sound quality it is fairer to compare it with the SOtM and it's a good bit cheaper, out performs and not so chunky to use with an app. At the moment I would say Volumio is a better interface to work with But certainly better than the SOtM interface
I don't really use Tidal or Qobuz so the issue I mentioned does not affect me

Great result, John! Sounds like impressive unit. We'll have to have a streamer bake-off at some point - I'd be very interested to compare it to the Pro-Ject.
