Hi Coen,

What is the cluster size you use with NTFS ?

Alain
PS: Did you try ExFat also, with 2048k clusters ?

Hi Juan,

Not really... I only conveyed the information that was on CA...

Alain 

Thanks

It is probable that many have seen this, but anyway...

I was wondering... About this project about putting part of the system in another room... What would be the maximum "acceptable" total capacitance before a degradation occurs between the dac and the power amp ? Aren't balanced cables supposed to allow for good signal transfer through some length ?

I would need about 36 feet of cables to accomplish this project...

Alain

I tried with the suggested SFS and I would not swear that I hear an improvement (because of expectation bias), but I feel LF have improved. It would require longer listening to determine the real merit of it, but I can say at least that the results are very interesting !

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...

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...

Alain

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...

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
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...

This links gives specifications about the cables I bought.

I just checked the cable capacitance... It looks quite too high for what I was attempting to do... 46 pF/foot. This multiplied by 75 feet equals 3450 pF...

Ok, will try with the 6 feet version again, to see what it comes to...

Guess I forgot a few questions before getting these...

Alain
PS: This hobby can get quite frustrating when someone is acting "in the blind"...

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 ?
