Hi Michael,
While I do not have the same motherboard as the one installed in the XXHE PC, the advantages in having the same components are many as each new tweak and XXHE implementation "should" have the same effect... This makes everything easier to share: ideas, discoveries, perceptions, etc... But of course, it does not mean that you absolutely need to have the same machine...
Regards,
Alain

Hi Cohen,
Well that is beyond my knowledge (if I have a different NOS1 or not)... But each time I forget to put that switch ON (5v), XXHE brings a window (2 consecutive windows in fact), indicating "No sound card"... So I shut XXHE, turn the 5v switch ON and restart XXHE. My NOS1 is almost ON all the time... Maybe I shut something in addition with what Minimize OS does, so that could explain this, but I am not savvy enough to put my finger on it...
Regards,
Alain

It cannot harm to look at the errors in the NOS1 driverpanel allthough you will probably find nothing there. I think my execution was too poor. Also I suspect the cut screen to have more to do with the errors than the cut 5V wires.
Regards, Coen
Hi Coen, When you did this (cutting the 5v), how was XXHE reacting when you loaded it ? I ask this, since with the use of the Sotm USB 3 PCIe card, I can either have the 5v switch turned ON of OFF. And when I forget to turn it ON the first time, XXHE does not see the NOS1... Only after I have loaded XXHE, then I can turn the switch OFF... Alain

Hi Alain, A fellow has loaned me a set of these single ended cables to compare with my expensive interconnects. Note the Blue Jeans LC-1 capacitance of 12.2pF/ft (a third of the capacitance your cable claims). I have not had a chance to spend much time with the loaner cable but I will throw it in now and let you know what I think. EDIT: The Blue Jeans cable is very good. It is uncomfortably close to my high priced interconnect. Cheers, Anthony Hi Antony, After my last post, I disconnected the preamp and tried again with the 6 feet XLR cables. Quite a difference, even if they stiill have a high capacitance. At least it proves to me that my plan on moving a part of my equipment, while a good idea at first, had a serious flaw... Thanks for your help ! I do have good single ended ICs, but I wanted to use the balanced cables path... And yes, I am considering BJC for the replacement Regards, Alain Alain,
I can imagine that you now need to attenuate too much ? More than 48dBFS is a no-go anyway.
Peter
Well.. Unless I do not understand the question correctly... No ? With the preamp, I have more range for the level (up to 8V)... Funny you mention this 48dBFS, because I read the documentation about the NOS1 once again last evening... I had moved my equipment, plugged, unplugged, plugged again quite often for the recent months (ground loop and this)... I think I will rest from that... After I have decided what to do with my subs !!! Because if I decide to keep them, the preamp will again have its place in the equation... Alain

I Anthony,
Thanks for this input. The store wher I bought theses cables is meant for musical instruments and it could be possible that the capacitance is higher than expected ? I used two different lengths (6 feet, then 75 feet). I questionned my choice about such a long cable, I may have been wrong to assume that since they were balanced cables with standard quality, it would not impair the SQ...
On the other hand... I am not sure that choosing a Spectral Audio power amplifier was the right choice. It can deliver a frequency response up to 1.8mhz and with the unfiltered output of the NOS1, it could harm the tweeters... That I have to check too...
Food for thoughts...
Regards,
Alain

For the last week, I have been listening to music with the direct connection between the NOS1 and the power amplifier, as recommended. In other words: without the use of my preamplifier.
I used balanced cables (XLR - 6 feet) first, then reorganised my system with longer balanced cables by installing the music PC, hard drives and NOS1 in another room, leaving only the power amp and speaker in the listening room.
Something is wrong. I don't have the same "presence", same rich SQ in this configuration - as opposed to having the preamp in the chain. The music sounds kind of lifeless when I use XXHighEnd digital volume. I even feel that I have lost some accuracy... ?
Am I missing something ?
Alain
