Hi Ramesh,

I did not try using the short Clarixa cable, as the last time I tried that, it affected SQ badly.

That is at least the same as our experience, with assembling the "good cable" also inside for its 15-20cm piece or whatever is required.

I now may wonder what happens when you'd put the Lush^2 in that position. Of course it is not a "short cable" any more in that case, but this isn't necessarily bad at all. Now I forgot whether you also have a Lush^1 but if you do, try the Lush^1 where you normally use the Lush^2 and put the Lush^2 in the "short cable" position.

I offer this option because that short cable could be highly sensitive to radiation and the isolation chips is also ...
And this is how the Lush^2 could explicitly be of help here (all the shields).

Haha, thank you for you kind words, Shreekant.

Kind regards !

Well guys ... sorry to hear this ...
For me it is the same. For "a whole world" it is the same.

I just sent a message to Tidal Support on what to do. I hope they ever answer, because I didn't contact them in years and possibly things have changed there.

I really can't tell where it happened or what happened, but the offered download indeed does not show the a. But Scrolling works indeed (I just checked it).

Apologies for the confusion ...

Hi there Stanley,

I'm afraid it should show 2.11a. Thus you must be doing something "wrong" ...

Best regards,

So Jack ...

You're not one of the astronauts on Space-X, right ? You sound a bit like good-bye for ever.

What I certainly do get from this is how Covid-19 is getting to our nerves. Small example from this afternoon for us :

We were driving from Arnhem to the west a bit and back, just following a nice route. Hardly doable with a 1 million bicyclists on our track (they own the small roads these days), so half way we took a short cut on that route and decided to visit family in Arnhem. Our son Paul was driving (all right, he was our friendly chauffeur) and his mood went bad. Why ?

He is now more than two months performing his (EE) graduation from home while normally this would have been at the firm hospitising him for his graduating internship. On a side note : he is the only one from his group who will manage to graduate because all others failed to arrange for this "working at home" in time and the others will continue with that in October.
And thus his mood went bad; we shouldn't visit family, of which she out of all is practising physiotherapy.

And so I changed the navigation to "back home" and there (45 minutes later than could have been) I grabbed my beer (I am lying a small part here Party).

The moral : in the G-D 4 hour trip nothing was open for a beer.
This is killing, right ?

Jack, next time you reach Arnhem, step on it and end up 50Km or so more north for a beer. Last time we miserably failed.

This is now solved in 2.11a.

People can download this and unRAR and paste over the XX folder of the existing 2.11 version (and only 2.11 !) :

[removed - is now contained in the normal Download files]

Hey ...
Yes, I know, this is a bug I introduced close to putting 2.11 to production and I couldn't find the solution easily.
It's in that ToDo I showed (with *) ...

I will try to solve it soon.
Kind regards,

Hi Fralippo,

The so-called Release Notes of this version, tell that I searched for this bug endlessly, but that I can't find it. And worse : this has been solved at some stage, but it sneaked in again.

As far as I can tell this only happens from album to album (so have a playlist with ten tracks from 10 different albums and it occurs after each track). So surely it happens at the end of the playlist.

If it occurs to you with an SFS of 0.39, well, then you have "noticing" ears. Of course you can hear it because a "chop off" really occurs, but this will now be so marginal that I would have difficulty in knowing. With an SFS of 10.19 it will be dead-clear alright.
And if you now tell me "but this really does not matter for chopped off length" then I have been debugging in the wrong direction ...

Kind regards,
10  Ultimate Audio Playback / XXHighEnd Support / Re: General questions about Arc Prediction Custom Filters on: May 01, 2020, 01:13:36 pm

Hi there Zheng,

Let's see whether I can answer your questions adequately;

First off, digital filtering always comes along with upsampling. This is hard to explain, but I could try to convince you that only the upsampling step allows to have the result mostly the same as the original. Think like injected additional samples while the original samples remain. But mind you, this is typical for Arc Prediction and this means of filtering is far from common (at all).
The more upsampling steps, the more samples can be injected in between the originals. Thus, with 16x upsampling, 15 samples are injected between each 2 originals. Let's say that they imply (and hunt for) a better transition from the one original to the next original. Not "one big jump" but in 16 small (calculated) steps now. Or in two steps when upsampling is just 2x.

"Custom" Arc Prediction is not really different, BUT in this case a second stage filter is applied on top of the normal Arc Prediction. This is done the most mildly where the (possible) transients of Arc Prediction are sustained. In this case, however, the original sampling points are changed, as in any normal digital filter doing this, but with the notice that this is "measured" (by me with the analyser) to not noticeably change the transients. Do notice that a normal filter will change the transients notably, me always stating that it will changes violins into flutes (think micro transients, implied by the bow and the resin onto the string - the more resin the more "jumping" (transients) on the string).

The more times upsampling, the better the filtering can be applied (this is a story in itself). But notice that this is generally so, because it also can depend on the behaviour of the DAC at higher sampling rates (it needs to process more data and this in itself can be audible in a negative sense). And indeed it is so that some people play our NOS1 DAC at 352.8 instead of 705.6 (upsampled RedBook); less current is used now, which may mean that more reserve is there for stuff like again transients.

As you can see, the transients are almost a hobby-horse to me. The accurate rendering of them is key (in my view).

When playing out 44.1K (from 44.1K) no filtering can be active. Still it may be so that the software may "touch" other parts which again imply processing, but now in-software only. And mind you, as we know, XXHighEnd is "tweaking" all over the place and this is about processing (all over the place). Also more physical things may be in order, like you outputting 44.1K all right, but maybe outputting in 24 (or 32) bits, while the original is 16 bits. Officially this can't matter, but now physically it may imply half more data (or double) towards the DAC, which now must process it.
And as we also know by now, everything matters ...

What are the filters in the group [NOS] for? ony for Phasure DAC?

It is that you mention them, otherwise I never even saw them. I suppose they sneaked in the production version, from some testing a long time ago. Please don't use those.

I hope it is all clear a little !
Kind regards,
11  Ultimate Audio Playback / XXHighEnd Support / Re: Tidal om XXhighEnd and new computer name. on: April 18, 2020, 09:41:56 am

Funny ... If you look in here XXHighEnd Model 2.10 - Respecting Selection Sequences & SQ+ with uneven SFS and in there you search (Ctrl-f) for RAM-OS, you can see that I made something for it. But what you as the user must do for it ? no idea. Anyway, this has been made explicitly for those using the RAM-OS Disk twice (like for old Mach II and new Mach III - you'd just have the RAM-OS Disk twice (your case obviously)).

Fact is that the reference from within RDC always should go by means if IP address, with the notice that I see people have that working with the computer name. And at least that can cause problems to begin with. So probably the issue would be that you work with a computer with name RAM-OS and this is now the Music Server PC and that the RDC connection does not allow you to connect to that same name, that being the Audio PC.
What I had to make for that, I have no idea any more, but the Release Note I referred to tells I did.

Hi there KNB,

I know what you mean and theoretically this can't be solved by means of "no re-activation" of the Music Server PC. However, a special "install" environment exists to cope with "this", noticing to myself that the "this" is quite unknown by myself by now, not even knowing what it exactly is what you want to solve. I mean, re-activating the Music Server PC can't be the problem, right ? (but ask for a new Code)

Real point is : the two times the same Computer Name is the recognizable issue for me. And I have made something for that, of which I forgot what it was ... (or why it was really necessary) ...

Regards for now, sleeping

Hi Joseph,

These are good questions. I do this from the top of my head now, so ask if you see different colors :

- No color (black-ish red) : Audio Engine (program) is not running at all. Notice that this can be incurred for by clicking the led (kill Audio engine).

- Blue : Audio Engine is in memory, but idle.

- Red : Audio Engine is playing Audio momentarily (should be audible).

- Yellow : Audio engine is playing Audio, but is Paused by means of Alt-E (continue with Alt-P).

Only the latter will do something to SQ, once it is in this sate for several hours such as 20 hours after Alt-E was used on the last Playback session (internal special quiet playback on-going).

I hope this helps ...
14  Ultimate Audio Playback / Your thoughts about the Sound Quality / Re: V 2.11 an opus magnum on: April 14, 2020, 04:04:37 pm

Hi Juan,

when I click play I see that the album is read by the 12 cores.

You seem to skip a step there, which is : check by means of TaskManager how many cores are active now. So if you had 12 (hyperthreded) in your example it should show 8. If it still shows 12 *there* something isn't working ... Esepcially not if XXHE=s Boot Menu shows the 8 after a reboot (Reboot is necessary !).


Kind regards,
15  Ultimate Audio Playback / Cables (Community induced) / Re: The greatest invention in/for Audio (Lush^2) on: April 14, 2020, 04:00:13 pm

Yea, see ? That changes the start-up sequence. In this case : first start the device(s) (they run now from the source as well as the target) and then connect the cable (it starts to push-thru right away).
Btw, leave it like this and better don't re-attempt. Haha.

Regards and thank you for the feedback.
