The design of the rack must have an influence. Presumably Naim equipment is optimised to work on Naims rack.
As the limetree will presumably be used on a variety of different supports, it’s probably not possible to state a particular type of feet will always be optimal.
Try designcable.com. They are in Nottingham. They are priced reasonably and to my ears better than any thing by QED.
I’ve reached a conclusion here. The Limetree is an amazing machine. I have one in another system and it’s a keeper.
But as good as it sounds on my main system, especially with Tidal Max, I’m going back to native NDS and its glitches.
The Limetree sounds good with my NDS. Very good. It’s a sound I could happily live with, and the functionality is excellent.
We’re getting into small margins here but the sound signatures are different. Native NDS has an analogue roughness to it that the Limetree polishes off. And I like that roughness. It just grabs me that little bit more.
I won’t be looking for any more transports for the NDS, I’m just going to accept what the NDS does and how it behaves.
It’s been an interesting experiement and big thanks to @Blackbird for your help on this. And to anyone considering a Limetree, my advice is give it a try. It has a very appealing sound.
Maybe the Innuos Pulse can retain the Naim sound signature ?
At least the PhoenixNet does it.
The Limetree was close. Very close. But any possible deviation is enough to distract me. I’m not saying the sound was worse with the Limetree, not at all, but there is a very strong and clear signature to Naim. As I said, the word that struck me was ‘roughness’. The Naim sound in my system has a certain edge that reminds me of live music listened close up.
Which digital cable did you use? I have 5 different digital cables here now including a Bridge II and all combinations change the signature.
You use the standard SMPS or?
I used a QED Optical cable
Never tried a better digital coax cable? I’d give that a try if I were you knowing how much they can improve the sound but you seem to have decided on your path now 
I didn’t use the best cable, no question. And I won’t be selling the Limetree just yet. But I just like familiarity.
I noticed on my other system that the Limetree has a very sophisticated sound. It isn’t soft, top ends really sparkle. But it lacks that Naim roughness. Others might say that’s a good thing I’ve tried different cables with the Limetree and they’ve improved sound but haven’t changed the signature to my ears.
Is that a similar feeling as cohesion meaning the sound sounds together and not separated? If so I understand what you mean and it is a fine balance to keep it yet still get more out of the system. I’ve had very expensive cables in my system that some might like very much but which lost the naim cohesion and drive of a performance which is what makes it sound musical and engaging. In my experience it is possible to keep the naim signature yet get more information out of it but it is a puzzle to make it work and it’s not always more expensive means better.
The native Tidal presentation to my ears might be bit more together but lacks dynamics, air, soundstage, depth, micro details and all this but I very much understand if one prefer one over the other. I listen mostly to jazz and love the presentation Bridge II with the rest of my digital chain presents to me since it sounds more real and alive than native Tidal. All choices are the rights ones as long as we like what we hear 
The worst type of cable to use with digital sound.
Try a good 75Ohm coax ideally RCA-BNC into the NDS.
However any protocol conversion to S/PDIF is going to be compromised. That standard allows for jitter. It was a compromise design between Sony ‘S’ and Philips ‘P’ just like the CD Redbook standard. If we could have just had 24/48 then! Or even 16/48
Toslink is certainly the worst type of cable to use with analogue sound. 
Good quality toslink can be as good as coax up to a point. Probably 2 or 3 hundred pound coax cable.
However, it can’t compete with coax costing thousands.
Hi,
I agree with the nds being warm and very analoge sounding (wich I very much like) but on the other hand having some edges which makes it very involving. But I know only how it sounds bare. On the other hand our systems are very similar
Or do an even bigger approach, like innous pulse or pulsar (both with lps inside)
Might aim for Aavik S-280 if going anywhere.
I’ve heard Bruckner on dCS and Mahler on Naim, and remember the timbral beauty, but the sound right out of the S-280 box and its analog signature, really put the hooks in me. I think once you hear it, you’ll be convinced. And hearing it through your setup may be a game-changer. I should add that the cabling attached was mesmerizingly good and very expensive.
Big Dan didn’t said that bare Nds is better. He just preferred it vs the Limitree / Nds for local streaming. Another one too. Preferred as more Naim sound. Another one too.
Tidal was not used.
I used it with ND555. Was hoping it would mitigate firmware issues. It didn’t although I wanted it to. It’s nice piece of kit in that it gives Qobuz to NDS. Useful with standalone DAC.
But prefer sound of ND555 to adding Limetree Bridge. Am keeping the Limetree for now, but its boxed up for rainy day!
Other than adding unsupported services to an older Naim device (a bridge lets me use Roon with my UnitiQute2), I fail to see why people are motivated at all to use an $800 streamer box into the digital input of a top of the line Naim streamer, versus the built-in streamer front end!
If you would be at my place listening to the difference you would understand complete 
The streaming section in NDS was old already when released. That’s why ND555 took its place using “same” streaming platform as Lindemann Bridge II.
Hi Blackbird, do you have any details on the modification for the Bridge, not much came up in a search?
