Hi,

Not the driver, just set the button closed to the NOS1 middlepart to off. This has to do with the 4channel trick that is needed for 16x bitrates (on).

Regards, Coen

P.s it is mentioned in the button explanation in the manual

You're right of course, with the switch back up I have both channels playing.

Re: Orelo MK-II Imaging.So must I go back to W7 because of this handful not working in order to let 1000s not work optimally ?
No. I refuse.
I better sit down and work out the frequencies where W7 behaves totally different from W8. That seems doable to me. Next I will be able to tune the speakers for where W7 is the better one and apply that to W8, Mind you, if so at all.

Done.

And you won't believe the story ...

Done.

And you won't believe the story ...

secret

Or maybe you do.

Let's start with me telling that I always wondered why the speaker needed a "notch" at ~90Hz. But, it needed it (to present a straight line performance) and so I applied it. However, it was in my mind that it could be a room anomaly, never mind I measure from very close (like 2cm).

So for a few weeks already I was tempted to remove this notch in order to see whether I'd receive a coloured sound from it, or whether it maybe would be for the better. And, after playing with Windows 7 for a week and perceiving the more deep down from earth bass - and after going back to Windows 8 that deep down being gone again, three days ago I finally did it.


Here you see that notch and this thus went out.

Within a second it was clear to me : Windows 7 bass was back.
Well, not for all its aspects (W8 bass is better) but the deep down earth was there.

Aha.

And maybe in the next 10 seconds I knew what has been going on, and it is almost too stupid to put into words, but still ... how to think of such a thing. OK, I didn't.

What I have been saying for about ever, is that it is actually impossible to tune for example speakers through measurement means which are different from what we actually use for playback. Do I need to explain this ? I hope not, because it should be quite clear that if an XXHighEnd dial is able to bring us better bass or anything, that dial will not be present in official measurement means (that doesn't play XXHighEnd Wink) and so ... what will we be doing when utilizing such means.

So I was smart and I did NOT;
I used XXHighEnd for it and just played the test tones through that.
Not that I thought of using special "good SQ" settings ...

Let's say I have been in dual mode, because from one side I know that such settings make a difference, but from the other I also know they are not measurable.
Uhm ...

Small intermezzo to setup some tense :
We are currently with 6 if I count in Bert who applies similar to the Big Orelo. 5 of us tend to "complain" about very maybe wanting some more LF output. Notice that it is allowed to include me after comparing to W7. But also notice that there's one amongst us who doesn't complain at all. Actually the other way around - he's the only person who deemed it necessary to move the speakers more out of the corner. And he uses Windows 7. Me too found the LF to buzz too much, and me too had the idea that the speakers could use some more "out of the corners". But I never payed attention to it really because my W7 situation was temporary.

So what is the common sense here ?

Like I said, almost too stupid to put into words, but ALSO, I'm sure, no speaker builder with his best ideas of it all will think about it ...

Don't tune your speaker on a Windows 7 machine while intended use is on Windows 8.

Yep. So logical, once we start using our brains somewhat.

So that is what I did; Using my W7 machine containing all the sh*t for whatever work, and it includes the DSP software. And the recording hardware and drivers and all needed to do this. Of course I am not going to load my W8 audio PC with that.
Of course not.
But I should have.

Without me realizing it really back at the time(s), below you see how the Orelino was tuned. Mind you, although the design in the basics is rather the same, the drivers are totally different. Please notice that although the MKII was tuned later than the Orelino, the MKII was tuned from scratch, and no Orelino (DSP) base was used. Here :


Same thing ? You can say so yes. There's a small difference in the peak frequency and also the range is smaller, but with the notice that this has been for myself only and wasn't setup in as much detail I applied for the MKII which was "for you". But you can bet I would have come to the "more same" when I had payed as much attention (and no exact 90Hz would have been used, to name something).
Anyway, same thing.
So :

Quote
Done.

Yes, with the big fun that I already had it done without me realizing it. So, assumed it is W7 which needs this while W8 does not need this, this is the difference for W7 against W8 in the LF area.
Please notice that this now has been determined audibly and that it is of course no real science that I myself judge W8 (without the notch) to sound the same now as W7 (with the notch).

For me this does not imply a buzz like W7 shows it, so I am the most happy with this. I suddenly found the best of both worlds ... The bass quality in optima forma, with the highs quality W7 never will show. The both combined makes the more profound highs more soft in the mean time.

Nice.

Nice, but how can it help people not being able to tune their speakers like Orelo MKII (and due Orelino) owners can ?
I really don't know in what direction to talk;
Highs should be way more profound from these mid-high horns to begin with, while bass is also way more profound to begin with. Fact seems to be that Windows 8 needs a boost of similar shape and position you see from the notch I had to apply. Don't ask me what reality is. I mean, when I had tuned the speaker(s) under Windows 8 that notch would not have been there and Windows 7 would have been deep down earth exploding; we know how much 2.5dB means for the low frequencies ... way much. And my W7 already showed a tad too much of it, let alone that 2.5dB could be added (I didn't try for listening).
It also won't be true that most people suffer from too much bass under W7, BUT, there are a few who can tune their speakers similarly, amongst them Coen who can't survive W8.

If the latter would be a measure then W8 must be the mere reality and those used to W7 should encounter a better bass quality in W8 (plus less grey in the highs).
And so, if this is correct both people like Coen and the MKII owners suffer from similar under W8 - too few bass output around that 90Hz region. They all tuned their speaker for Windows 7 ...


I hope this made some sense. But of course it was quite a revelation that I announced to be able to find the difference between W7 and W8 by means of measurement, while I actually already did.
Stupid stuff ...

I've just run a series of 1/3 octave band tracks (ripped from the MFSL 'Soundcheck' CD), from 20Hz up to 20KHz. It's clear that there is a 'suck-out' between ~40Hz and ~80Hz in my room. I've never noticed this before. The 20Hz, 25Hz and 31.5Hz tracks show plenty of energy (the 20Hz can hardly be heard, but it definitely energizes the room). There is a significant drop in energy on the 40Hz, 50Hz, 60Hz and 80Hz tracks. The energy starts returning on the 100Hz track.

Hey Peter, my comment here obviously didn't trigger your memory of applying the filter7 notch. Oh well...

Let's start with me telling that I always wondered why the speaker needed a "notch" at ~90Hz. But, it needed it (to present a straight line performance) and so I applied it.

I've just applied the Unity setting to filter7, and indeed the LF is much, much better. Nice 'tweak'.

However... over here, I'm still missing the really low-LF stuff. I've only tried a few tracks though, and it could well be that these simply have no real low-LF to begin with. (Or it could be that I really need to get the NOS1a and PC back in the main room and use short ICs.)

Yeah, my description of the suck-out wasn't very good. In my mind I had the impression of a gentle downwards slope starting ~40-50Hz, peaking ~80KHz [Edit: I meant 80Hz, of course], and then coming back up from 100Hz onwards.

Hey, not bad considering I was using widely-spaced discrete test tones and only my ears! (I really need to get hold of a calibrated test microphone, Earthworks or something, at some point.)

Anyway, the LF is now much better. But I still need to work on the extreme-LF... I need more!

Peter, I am having a serious wtf moment reading this. 

You are saying that w7 has a 2.5dB 'lump' in the frequency response at 90Hz that is not present in w8...am I reading that right?  How does this happen?  Surely Microsoft would have noticed this.  Surely someone else would have noticed this.

I can't even figure out the mechanics of how this is possible let alone why Microsoft have left it un-resolved (although something seems to have been done for w8.

This all makes me wonder why w8.1 could not be made to sound good.

Anthony, then you go claim that both sound the same ?

Otherwise you ask rhetorical questions with the most obvious answer that I don't know (and I am saying that from the start of W8 - there HAS to be a difference and I don't know where it can be, but at least I think I am one step further now).

On a side note (or not) what always puzzled me is that AmirM (former lead developer of Vista Audio Team) was asked the question (WBF through Mani) and he didn't even respond. Why ?

But the most logical is it has to be in "USB" somewhere. At least from that I can reason that a digital loop-back (to check bit perfectness) not necessairly travels the same path as when we go to a DAC. This is all driver stuff with also the notice that W8 is totally different here than W7 (with btw "solutions" in 8.1), and OS/X being even more of a mess.
IOW you don't know what (audio) driver developers all have to do in order to let USB work decently; it's completely tweaked by now (OS/X worse than W8).

What's a bit new is that I'll receive a new library for the driver which in my opinion can solve the stopping of W8 after 10.x minutes, which some people still suffer from. The message : It can happen that W8 forgets to ask for a new (audio) package, so the PC actually doesn't send it and sound stops.
Notice this is a derival from other issues solved in this library and whether it really solves that problem is to see, but it is (hopefully) a clear example for you.

Hi Peter,

Who'd thought about a midbass bump in win7 accounting for most of the difference in sound. Certainly not me, I had to read your post a couple of times to be certain win7 and 8 weren't reversed. I think win8 is here allready a little on the thick side in de midbass (and yes no feeling/suggestion of abyssal bass like in win7 too) and win7 just a tiny tad too thin...

In the mean time I've been moving some stuff around while listening to the macbook on the NOS1a. A music pc on batteries so to speak with a fantastic dac. I think this concept works dispite os-x not being entirely highendaudio friendly and the common ringing FIR filters you are limited to. Notable was how of lttle influence the enabeling/disabeling of the wifi was in this setup. With my iFi dac there is a great difference (on the headphone). Not shure what this actually means for the difference in windows between OSses, but it is mighty convenient for streaming. Whatever.

Back to the "serious" listening attempts: win8 is as hard to catch as an eel. One step forward and at the same time one step back. The worst thing of all: natural is the one word I wouldn't use for any of the outcomes yet. +2,5dB wouldn't change this either (I think). Bleh.

Interesting to know if the driver update solutions also impact sound quality. This is win8 only? I have not experienced any stops after the pagefile/reboot tricks.
