You can promote a speaker without marginalizing your audience.

In this video the new Beolab 90 fully active speakers technicalities are explained:

https://youtu.be/yC0hjRHCYs0

This speaker is designed in such a way that it is able to manipulate the directivity. The implications of directivity for the perception of location are mentioned as well as the link with the work environment of the sound engineers.

It is a speaker born out of passion for audio and thoroughness. Interesting material and imho relevant results are presented since we all listen to a stereo system and share the objectives.

regards, Coen

Ok, it seems I have solved the issue by completely deleting XXHighEnd-207 folder and then unzipping and running (unnecessary?) Setup.exe in the new folder. I have good sound now as I have had from W10 Enterprise LTSB trial mode Wink
Which services I can kill (disable) in W10 Services Manager and which are absolutely necessary for a smooth run of XXHighEnd?
I am not going to use the machine for anything else but music playing. Maybe only converting flacs to wavs.
Sorry for duplicate log file and here is the right one:

Just encountered same problem with latest Patricia Barber 24/96 FLAC download
http://www.patriciabarber.com/store/monday-night-live-green-mill-volume-3
I get blank screen with just mouse pointer during unattended play. Renamed cover art to GreenMill3.jpg but got same problem, renamed it to Folder.jpg and it works.

(Not her best album)

The other day I asked P.B. (you know) and it was the 4th time in a row that he just did not respond. Maybe he does not like me any more for some reason.

Hmm ... I just learnt that he left Tidal close to a year ago. That explains all ...

Hi Bert,

Great that you managed.

The setting of a "too low" filter is allowed, but a kind of a waste because you won't be utikizing the upsampled headroom for the Custom Filter. So, not advised but allowed (the other way around is not allowed because we can't filter beyond the Nyquist freqency (in this case after upsampling)).

I was clever ( I think :-)) and saved the new Mojo settings and loaded settings for the original driver. I noticed it sets everything except... the driver.

This depends a bit on the environment of the Save. Notice this goes by "sequence number" of the Drivers listed, and when you meanwhile eliminated a Driver, the sequence number of the one you originally used will have changed. So I think this will already happen when you go from Normal OS to Minimized OS. Well, not sure because it never bugged me and this can be coincidence (number can stay the same). Anyway I think this is explainable.
Btw do notice that I am not even sure whether you really mean Driver or possibly something else like Filter setting (it just reads like you may mean something else).

One final note. When loading original settings, so presetloader.xxsi, the XX screen shrinks to a small size.

Not intended but very well can be (a bug); dealing with the "scaling" is relatively difficult and the moment of saving happens under the hood in "normal" Scale Factor and the scaling is restored at start up. So I guess something like this last step is forgotton now.
Thanks for mentioning this.

Best regards,
Peter

Guys, don't be too quick to instantly dismiss Floyd Tooles works.  Without his decades of research and constant access to R&D funds to set up and perform literally thousands of blind tests in pretty much the same controlled environment I think that speaker design would still be in the dark ages...hit and miss. 

As a result of his work we know that controlled directivity and even power response are THE basic things that make or break how a speaker sounds.  His work also tells us what "most" people like to hear, and that is a diffuse sound field (i.e. lots of room reflections) with the reflections being the same frequency spectrum as the direct sound, which is where controlled directivity and power response come in i.e. a speaker sounds exactly the same on and off axis.

Of course one test setup cannot test every variant of speaker design out there, but I really do think that his basic results are indisputable.  It does not mean that he has tested everything that influences sound quality, but he does know the easy way to make a speaker sound "better", and that is the radiation pattern of its sound field.

The Orelo MKII does not have the ideal radiation pattern that Toole promotes because it uses a tractrix horn expansion (not conical or OSWG) but it is a point source and it does control the directivity of the sound above the room frequency.  Funny thing is that most of those that actually "listen" to horns prefer the tractrix expansion to those couple of expansions that are more technically correct.

As for the power response, I have no idea how the Orelo MKII fares, that stuff is difficult to measure so very few actually do it unless you have a facility just for that purpose.

Peter,

To date I have been a bit "meh" about the MQA stuff in general, but if you are suddenly excited by the possibilities then I will be as well. 

If the result is access to "the best masters" of the recordings plus with XXHE we will end up with a mix of fabulous time and frequency domain then that does sound very nice to me.

Cheers,

Anthony

Ramesh,

A few steps higher ..... Wink

So called uniform response is a unicorn.... in what domain is it? just power ... not enough ...  Happy  other variable are indeed required.

I'm putting forward the conclusion ... with what Bert/Peter have achieved .... controlling the reflections will enhance the systems performance well beyond presently possible ... wide/narrow dispersion or otherwise ...... All it requires is to incorporate room treatments  Wink

New acoustic panels and new position of the speakers now have near completely solved room interactions.

If you are visiting LA, round 2 ....  Happy

Hi, Peter,

Yes, that was the missing link. Missed that setting. After I set it to 32/768 I could set the upsample rate to 16 times. Great.
So, that is solved, but what I noted was that the filter setting was still on 176400 instead of 705600 and it worked, see screendump. So, does XX not check on this Filter setting? Well, yes, it seems it does because if I set it to 705600 and then go back to original driver settings (176400) I get an Q5 sample rate mismatch and this makes sense. So what happens if I select this new Chord driver with 32/768 setting and 16* upsample rate but leave the filter on 176? I don't get this Q5 message.

I was clever ( I think :-)) and saved the new Mojo settings and loaded settings for the original driver. I noticed it sets everything except... the driver. So, to test it I set it to the chord driver and loaded original settings. All settings were set except... the driver. Is this OK?

One final note. When loading original settings, so presetloader.xxsi, the XX screen shrinks to a small size. It didn't do that when loading the Mojo settings. A little bug?

Bert
