Hey Peter,

I had guessed that you might have been looking at the possible reasons for the SQ differences. 60k lines of C that is some program.  It's a facinating explanation of what could be happening, thank you.

So I think you are saying that buffer size is the simple product of q1 an xq1, but q1 is also used elsewhere in the engine by itself to influance timing. Now you have explained this it may make sense in terms of what I hear. The SQ difference I get when selecting a lower q1 value (of course whilst ensuring the q1, xq1 product remains the same) is similar in character to changing the timer resolution setting.

It's good to know my hearing is not changing slightly each time q1 and xq1 "pairs" are changed  Happy

One thing I have in mind for very sure : the best sound I have now emerged 3 days ago after a reboot, but this was a special reboot which applied something special ... new to 2.11 ...


I am really looking forwards to this, I cannot wait.....

Kr,

Nick.

Ramesh hi,

Can you hear any difference between q1 30, q1x 10 and q1 15, q1x 20. The latter sounds really nice here.

Your system is very similar so it would be useful to understand if you hear a difference too.

Regards, Nick.

Hi Nick, I will try what you suggest but is your signature up to date especially OS version and Xx version?

Robert

Robert hi,

You are right, all up to date now.

Interesting that you hear differences too and feel q1 15, q1x20 to be the better settings.

Either we both have a common problem with our systems or something is not working as expected. Either way for now q1 15 and q1x 20 is definitely favourite here  Happy

Regards Nick.

Hi,

I have been playing with Peters new settings:

Q1 = 30
xQ1 = 5
SFS = 0.69
Q3,4,5 = 1,1,1
Core Appointment = 3-5
Nervous Rate = 10
Wallpaper On, no OSD feautures

Sound is pretty superb, but felt voices were lacking just a little prominence and dynamic, as a result emotion was not quite as strong as it can be.

Changing q1 to 10 and xq1 to 15 has really bought back the emotion and presence. Everything else remains very enjoyable. Mybe bass pitch resolution is a shade more smeared but overall these setting are nice. Might be worth a try.

Nick.




Peter hi,

I am back to this point about  q1 and q1x again,  where sound changes for different values of
q1 and q1x values which produce the same mathematical product.

I'v been playing using q1 30 and q1x 10.
Changing to q1 15 and q1x 20, "definitely" changes sound. The presentation is much clearer and noticeably more dynamic, emotional and musical with the latter setting. Since I last posted above on this, the resolution of my PC has majorly improved, and its now very easy to hear the difference between the setting. The change in sound is repeatable when switching between the settings, q1 15 and q1x 20 just sound so much more musical.

It might be worth looking at how the parameter(s) are passed to the XX Engin and or how they are handled internally something perhaps not behaving as intended with the potential for better sound with certain settings.

Kind regards,

Nick.

Gents,

Your issue is proberbly nothing to do with this but I mention it as was unexpected and therefore a difficult intermittent problem to find.

Some time ago I had periods were it was difficult to connect my PC to the NOS1, also periodically the connection would drop or I would get a high number of usb transmission errors whilst playing music, usually when bass notes were struck. Finally SQ was just not consistent session to session.

It drove me mad. I was doing some very complex stuff in my PC at the time with countless iterations and listening sessions. I just could understand the variability in SQ I was encountering.

Won't bother you with how the issue was isolated, but it turned out to be the short USB cable on my NOS1. Once it was pinpointed I put a meter on the short USB d+ and d- pins. The resistance was all over the place anything from 100 ohms to a few K ohms ! The culprit was the moulded connector at the small end of the cable. Move the cable near the connector and the resistance went anywhere.

The attached pic shows the cheap replacement cable I made up. The new cable stopped all sorts of SQ and connection vairiability problems including some PC to NOS1 USB cables being better at connecting than others.

Stanley

A as mentioned above your problem most proberbly not the same but it might be worth replacing your short cable with a spare just to rule this out.

Kind Regards,
Nick.

Peter hi,

Thanks, for all the very useful information.

I assumed that you would not have used the NOS and XX as the calibration signal source for some of the reasons you gave but just needed to double check. But very good to get it confirmed so I can cast my attention back towards my room and pc setups and trust the DSP curve.

In another answer where I spoke about relativly large bass cone deflections you mentioned that these large excursions generate second harmonics. In the real time FFTs of low frequency sweeps Iv been looking at, and just as you said, when cone excursjons are large those second harmonics are present ! This is not too much of a concern whilst listening though as the bass sound quality is still superb.

On a happy note, its very difficult to overstate the transformation in bass sound quality that the dsp tweeks to compensate for rear wall and corner reinforcements have made. So as not to go off topic in this thread I will start a new thread on the tweeks, it just may help other owners.

Regards,
Nick.

Peter hi,

Im doing some work on room matching my Orelos IIs, I'm very pleased with results so far. I have always had significant bloom in bass due, I think, to rear wall / corner interactions. I have appiled some simple DSP adjustments that have vastly improved bass reproduction. I will post the method used in case it is of used to anyone else when I'm satisfied with the results.

Doing this has raised a question if you could help.

When you generated the bass response curve for the Orelo IIs, that you put up in the graph in the first post in this thread, were use using your NOS1 and audio PC to generate the sweep signal that was sent to the speakers or did you use another device such as your DScope to create the sweep input to the speakers ?

The reason I ask is that with my current setup I am getting some significant driver excursions at  20 to 30 hz when I am playing sweep files through my NOS and when playing a few tracks with very low bass effects dubbed into the track. Im trying to work out where to focus attention to deal with this and it would help to understand how the the origional calibration took place.

Thanks and regards,
Nick.

Ramesh hi,

I think I might be able to understand your impressions so far. Extrapolating from listening to Manis system last week (Stealth III, blaxius^2 B:B,W,R) I can understand how the B:B,W,Y could sound a bit etched and forward:

The blaxius^2 is VERY transparent and introduces a life and a joy de vivre to the sound (I will be ordering a set as I just can't listen to my system easily since hearing the cables at Manis  unhappy ).

The Stealth III is more prone to mid / upper mid resonances than my PC.

I suspect that B: B,W,Y "works" here at the moment because this setting in part overcomes the relative darkness of my Blaxius 1 and my PC dosent reinforce the more forward presentation.

I am really looking forwads to listening again when I have Blaxius^2s in my system. For sure I know that I cannot reliably do more work on my PC or Lush^2 settings until the the cables are in.

Thanks for feeding back your thoughts. Its going to be fun seeing if my Lush^2 settings need to change with the introduction on the new cables.

Regards,
Nick.

Thanks Mani,

Might be with a try with A: B-W-Y-R, B: B-W-Y. Gives a very nice sound here but quite livley compared : B-A: B-W-Y-R, B: B-W-R.

Nick.

Hi,

Just to add another combo into the mix (Im not sure if this has been visited by someone before).

I have been using A: B-W-R-Y, B: B-W-Y for ages now. I think I got to this setup  trying to apply  A: B-W-R-Y, B: B-W-R in the dark and could not see the colours properly  Happy

For me  A: B-W-R-Y, B: B-W-Y brings a very livley but natural sound. Getting great presence and stage with excellent base weight speed and pitch.

Regards,
Nick.

Edit - notation was not the standard format.

Mani hi,

What Lush setting were we listing to yesterday at yours ?

Hey Peter,

I almost asked in the last post if it were possible for different values of q1 and xq1, that make the same product for example 150, to sound different.

I have just spent some time a: b ing q1 X xq1 values that give a product of 150.

I still think I can hear some slight differences BUT its more difficult to pick out than I had thought origionally.

Perhaps I have a case of placebo going on  Happy

Either way sound quality is really sublime, your settings are great  Happy

Kind regards,

Nick.

Peter,

Definatly keep posting here.
The CA thread is interesting but can be fustrating sometimes.

A lot of folks here use NOSs so here there are more likley to be relevant observations for NOS systems here.

Having said this, I cannot contribute for a week or so as Im half way through a PC power supply build  unhappy but will be back to this topic when the PC is running again.

Cheers Nick.

Tim hi,

Im using  A: B-W-Y-R, B: B-W.
Will give Peter's other config a go. I have been putting some hours on the cable to burn it in so havent tried anything else as yet.

Nick.
