Last night I tried SFS settings between 0 and 20.
<6: the sound is detailed, but also a bit "detached".
>14: it becomes too "mushy".
So I settled for SFS=10 and that seems balanced (in my system, for now and with the music I played).
A bit more finetuning: I now have my SFS=8.80 and the second highest High Filter Stanley Stanley, 8.80 seems to be a good value. I tried it with the Low Filter and here the sound is great. I'm also trying 8.0/Low F. that makes the sound a bit cleaner. Better for me here. I'm going to stay there for a while to see what happens. The sound in general is sweeter but I still have to see if some details darken Regards, Juan |

Hi Peter, I thought I had read something about it but I'm sure I've mistakenly mixed some concepts like galvanic isolation of the USB cable and removing the ground from the NOS1.
I changed the SFS again to 0.90 and the driver to 8ms and yes, it disappears what seemed to me a slight intrusion of the bass in the mids area. I have to keep listening but for now the sound is beautiful.
Regards,
Juan

Peter, after some time without unplugging the NOS1 I observe a variation of the dcoffset from the reference value, 0.77 / 0.55 to 0.98 / 0.79, maybe more. When I unplug the dac, the reference value only lasts a few minutes and then gradually increases until reaching the aforementioned values where it remains stable with small oscillations. I can not say that due to this I notice a deterioration of the SQ but it is certain that when the dac, the Audio Pc and the USB cable are unplugged for one hour or two, an improvement of the SQ is noticed.
In some post I read that it has to do, as you mention, with the grounding of the USB cable and the dac. I have removed the black wire from the grounding of the NOS1. Previously I was isolating the USB cable to avoid touching the Audio Pc chassis, then this isolation was combined with the Intona and now it continues with the G3. Are normal these variations of the dcoffset because they are the consequence of the absence of grounding? Is there a point when the variation of the dcoffset is stable (more or less) in the highest values when should all be unplugged?
Regards,
Juan

Anthony, it would be great if you told us something more about your vibration isolation stuff. With those results, it's worth knowing. Please.
Juan
I will share Juan,but to be honest I have just started on the project. The way I see it there are three stages and I will start a thread after I have completed the second stage...which is 90% done. This month hopefully! Thanks Anthony, I'm curious, it seems like an elaborate project. Regards Juan |

Peter, have you listened to any ACDC with the new settings? Wow.. Not particularly with these settings, but maybe two weeks ago 3 tracks from my Demo Gallery passed by and I wondered where the nastyness had gone (ADDC is not always the most friendly). But since I was just playing music from a larger playlist, I forgot to revisit it. So I guess I need to now ! I expect guitars with a lot of air in them and with a 2 fold more fundament and even punch. More slick too. Am I right ? Regards, Peter Dirty Deeds was the album and the guitars are just like you say...but the whole presentation is so profound and spectacular and the soundstage sooo very wide and crystal clear. A while back I made some fancy vibration isolation stuff for the NOS1a G3 and it cleaned up the mids and highs tremendously without changing any software settings. The change of sound was not subtle and I had to get rid of my cheap-arse speaker cable for something a bit more suitable to tame the presentation...which worked. Anyway, these new settings combined with my anti-vibration stuff are just fabulous. Anthony, it would be great if you told us something more about your vibration isolation stuff. With those results, it's worth knowing. Please. Juan |

Yes Peter, the sound with your latest settings is spectacular. The basses are bigger, not sure that they are also deeper, there's more detail and also the soundstage is wider and deeper. In moments I had the feeling that the upper bass invades a bit the low mids but I can not be sure, I comment it just in case it can give some clue to make an even better sound.
Anyway, I like these settings more than the ones I have until now. As I say, spectacular!

After some time, too much, I returned to find the sound I was looking for. I was playing with the position of the speakers but I knew that something else was missing. Thanks to the suggestions to change the Q settings and also to discover that the change of seat I had made was a bad issue I found the solution. It seems strange and it cost me to realize. I had always heard from an armchair with a backrest under the shoulders and it occurred to me to change this chair for one with a backrest that reached over the ears. That was really a bad idea. It may seem silly but the fact of returning to my usual seat with the backrest below the shoulders has given me the spatial and airy sound I had before.
More important has been the change of the Q settings. Now I use Q1: 15, xQ: 1. Q3: 0, Q4: 1, Q5: 0.
Q1: 15, xQ: 1 softens the sound a bit with respect to Q1: 14, xQ: 1. But the big improvement comes especially with the change from Q3: 1 to Q3: 0. That, dramatically changes the bass making it deeper and more controlled.
Now SFS is 4.0 max: 120
In short, happy again.
Juan
