Peter, not sure what you mean above: I didn't mean to relate the issue to the "OS session." In all XX versions after 2.05, regardless of the OS being used, if you set the nervous rate to 1, it is not saved upon a shut down. When you again boot up the nervous rate automatically reverts to 100. Once I set it back to 1 it stays at that value throughout the entire XX 2.06 session. So you can stop and restart tracks and the value remains one. (With 2.05 it reverts to 100 every time you stop/restart a new track.)

My suggestion is for a patch that will allow one to save the nervous rate to 1 upon a shut down for all versions of XX after 2.05. I'm currently most satisfied using 2.06.  It's no big deal but sometimes I forget to set it to 1 after booting the pc and it takes a few minutes to remember why the sound is off, and I'm only getting older.......

One other thing about setting the nervous rate to 1: you must reset it every time you reboot because it automatically reverts to 100 after a reboot. Peter said he'd address that bug in the next release. Though it would be great if a patch could be created so it could fix the bug in other versions. I'm currently using 2.06. 

A couple of months ago I did exhaustive testing of my settings trying to figure out a particular issue. I found that setting the nervous rate to 1 was a significant SQ improvment. At 100 there was a glare to the sound. At 1 the sound is much more relaxed and neutral sounding.  YMMV.

Just made a change in my signature (SFS from 1 to .02) and it worked. Not sure what happened before. As always, used the "Forum Profile Information," button, under "Modify Profile" to make the change. Then hit save.

But, on second thought, it now seems more likely that I've been using a nervous rate setting of 100 for a long time, given the nature of it since 2.06, and that's what my signature reflected. Only now, since something changed for the worse in my system over the last few months, changing nervous rate back to 1 (where it had been for years before 2.06) makes a very significant improvement in sound.  

Sorry for being uncertain about this.

Yes, I changed the Nervous Rate 100 to 1 in my signature and that caused the signature to disappear both times. About 4 or 5 weeks ago, while trying to sort out my SQ issue, I believe that I changed my signature nervous rate setting from 1 to 100 while erroneously thinking that the 1 was a mistake.

Yes, changing only that one thing caused the signature to disappear when I hit the "post" button, both yesterday and today.

Thanks Peter, nice to know I'm not completely crazy and my system has not gone wacko!

 Both yesterday and today I changed the nervous rate value from 100 to 1. No other changes.

Morning Peter. This quote is from the 2.06 release notes. The part in bold made me think that the Nervous Rate setting of 100 is automatically set to that value when one engages the "Mach II" button, because that is what happens here. As soon as I untick the Mach II button, I am able to reset the nervous rate to 1 and it persists.

HOWEVER: I noticed and heard this morning that upon boot up (I turn the audio PC off at night) the nervous rate value returns to 100 and I must manually reset it whenever I boot the system, even though the Mach II button is not activated. See photo below, which is taken imediately after boot. The left hand parenthesis is covering the 1 setting for the nervous rate. It stays at 100 until I engage the apply button. Again this is only after a reboot. This behavior also occurrs in 2.07.

Is this just my system or do all those with the MACH II button engaged have a nervous rate value of 100?

Sorry Peter, I did something yesterday and just tried again, and again it disappeared.

Just happened to me too.

Yes , activating "Stealth Mach ll" changes Nervous Rate to 100. As long as it remains activated, that value is applied every time the gui returns from playing a track. As soon as I deactivated "SMll" I could change nevous rate to 1 and it persists.

Over the past several months I've had a harshness in the upper mids and treble creep into my system. Its been driving me a bit crazy, especially after having over a year of gorgeous sound in my room. Several weeks ago a friend suggested that all else being equal it  had to be either the source, audio PC/XXHighend, or the DAC. I took the DAC to another friend who has the same DAC and there was clearly a difference in sound between his and mine, so I sent mine in to the manufacturer for a warranty repair. Since then, though, I also discovered a significant cause of the harshness(Another friend has lent me a HOLO Spring DAC, Kitsune Edition, while mine is across the country.) Not sure when but at some point the "This is a Mach II PC" field became ticked in XXHighend XTweaks settings, which, when activated, takes over XTweaks settings and assigns presettings to all EXtweaks values. Thus, my XTweaks Nervous Rate, once the Mach II was activated, was reset to 100 from my usual setting of 1. I believe this happened when I updated to either 2.07 or 2.09. The 2.06a release notes suggest that  the Mach II tab be ticked to prevent the processor from being overheated via improper XTweaks settings. Well with the Nervous Rate set back to 1, about 90% of my good sound returned. I use the original XXHighend PC motherboard without a fan. A Zalman Reserator provides water cooling to the processor, so for me heat is also an issue. I underclock the processor as suggested here and can say that having a nervous rate of 1 does not cause overheating and it dramatically improves the tonal presentation (at least here in my system)

Also, I have gone back to 2.06a as best for sound. After sorting out my XTweaks issue, I briefly tried 2.07 but it wasn't as natural sounding as 2.06a. It might just be that I'm a little exhausted trying to get good sound and I needed to give 2.07 more time/adjustments. But I'm so pleased with the sound now that I'm not up for more testing at this time. I intend to try 2.07 and 2.09 again in the coming months. Of course YMMV.

Thanks Peter, I play around with some settings.
