The problem you may have now, could be solved my means of reading the text under the second picture (and up to where the list begins) in this post :
Operating System Upgrade XXHighEnd PC

What it's really about is not supported by pictures, but maybe you can make something of it.

Let me know if it helps you,

These new settings are really worth a very long listen! I've been using the smallest SFS possible and now that all seems wrong headed with the new settings. The sound is much more relaxed and neutral. It feels as though my amp went from being 30w per channel to 200. Thanks Peter!

Yes, problem solved indeed. I had to change a lot of settings but now it works again.

There is still one strange issue left though and that is the following: in the bios I can only select if the computer boots from
1 - the 3.5" bay or the DVD, or
2 - the 2.5" bay or the DVD.
For some reason that I do not understand yet I cannot get it to boot from all three (not all three at the same time of course, that is not what I am trying  innocent ). In the boot order I can only pick the DVD and the 3.5" bay or the 2.5" bay even though I just cannot select that.

I checked the bios manual for this, but from that I understand that it should be able to do it, but no...

The reason I wanted this is because the 2.5" disk that contains win8 gives me a boot error that I thought I could fix when I booted from the 3.5" bay and then fix the 2.5". But that did not work. When I boot from the 3.5" harddisk I cannot even find the 2.5" harddisk in the explorer (or the dvd for that matter), so although the computer works again, there is still some strangeness going on.

Definitely more profound bass. Extended listening in my room has shown this. I have knocked back active sub output ever so slightly as a result. Bass on electronic music is better more controlled.

Highs are misleading especially in volume. Really noticeable when turned down how loud they were but clean sounding no distortion.

Hey Dave, congratulations whith your well-thought-over purchase, and thank you for this first report.

Now wait till the day that you can detach all devices (including the SSD for the OS) with as last step the video card. You will be (should be) amazed how much *that* alone will matter. After experiencing that, you will not be able to listen for one minute with the video card in. Promise. Anyway, that relatively bad suddenly.

Best regards,

I am one of the new owners of the MachII with OS RAM drive.  I haven't been able to spend much time listening or optimizing.  I currently have a mouse, keyboard, monitor and USB drive for music hooked up to the Mach II, so again far from an optimal setup.  Prior to the Mach II I had a laptop which is my comparison point for sound quality against another computer.  I don't have a lot of comments so far, but here are a few -

- First it is a remarkable engineering job from the hardware to the software.  I will post more on this later.
- Read the directions carefully, it is all there, but easy to miss things (or maybe it is my reading comprehension).
- I originally hooked up a USB keyboard and then switched to a PS2.  The sound is better with the PS2 keyboard.  To me this gives you an idea of how sensitive the sound quality is to the computer and how with this system you can hear the difference...  Of course most of you have known this for awhile.
- I'm not great at describing sound differences, but I'll give it a shot - bigger sound stage, better clarity and definition, more natural, and a lot more bass. I think the most surprising thing is I've never heard bass sound so natural on my speakers before.  Even though I am coming from a laptop, before the NOS1a I had a great CD player and amp and all the things I mentioned are significantly better except the sound stage with the same speakers.

I plan on using creating a direct Ethernet connection from the laptop to the MachII so I can RDP in.  This way I can take out the video card, etc.

As I progress more I'll post.  Looking forward to hearing other people's thoughts.

Hi All,

So ... what you see below is the picture of the first Stealth going out, just over a week ago.

High Resolution link XXHighEnd Stealth Mach II LPS Front
Switch at the right hand bottom is to turn on the cooling fan manually. Shouldn't be necessary but can be used to cool more than natural convection does, e.g. when you don't use the PC and now for even better longevity. Below you can see the (white) led for it ~1cm next to the switch.

High Resolution link XXHighEnd Stealth Mach II LPS Back
Large slider switch next to the power inlet is to cut mains Protective Earth, so it doesn't imply capacitance in the power cord when you want to play with without PE.

With some other jobs in between the lines, today the 6th of a first planned batch was going out. 2 have been shipped to new NOS1a owners so they won't know the difference anyway Wink and of two of the others we might hear something of, soon because they post here now and then.

Next batch is starting tomorrow with the knowledge that the due owners are all enjoying a vacation or are out for other reasons. bye So hold on for reports other than my own.

So Juan and others ...

Yes, I still agree with those settings fully. But I also see others using it persistently (not posting here).

When going back after these several weeks by now, the old settings sound more or less nasty. Stressed / squeezed.

Apart from the better balance in general, I am still quite sure that the deepest (sub) low bass is there quite more profoundly with the specialty of not colouring or tiring (all so easy with too much sub low) or strange otherwise. This is not a guarantee because I tend to think that I might have started to like such deep down earth bass, so I wonder what others actually think about it (and a reason to have moved this topic now to the Sound Quality board).

Meanwhile the super excessive highs I now have are IMO mostly caused by this setting - and strangely enough actually the thus *high* SFS. But I can not check against my old normal situation which was a normal (XXHighEnd) PC, while today it is the Stealth with Linear Power Supply. And that too for sure contributes to those highs.

I have more to tell about these highs but I don't know how to put that yet. Happy

This topic has been moved to Your thoughts about the Sound Quality.

If I recall correctly the different SFS had to do with the Silverstone being disconnected or maybe it was you who just wanted to compare with an older favorite.

Hi Coen,

The other day I remembered again ... There was this types of albums (or an artist actually) of electronic music, of which I told you "odd, these now seem to sound artificial and while it is synthesizers alright, I am disappointed because this didn't bug me, earlier.".
And so we both started to try things.

Btw, this music was from Gaya Project but I only played one track for example, fairly much in the beginning.

Regards and on behalf of others too, thank you. Happy

PS: I will move this topic now to the Sound Quality board because by now it really belongs there, while most people may miss it when it stays in the XXHighEnd PC board.
