Confirming that the problem was not with XXHE.  For some reason, the permissions on the music directory folder has been set so I did not have access.  Fixed now.

I activated the second instance of XXHE.  The problem is with the folder on the external drive.  Not an XXHE issue.  For some reason, I am not able to access the folder even with explorer.  I'll figure this one out.

I realize I violated a fundamental guideline by attempting to start the XXHE.exe from two different folders.  Just read the download procedures again.  Essentially I followed scenario (b) by extracting the full .rar file in a new folder.  I'd be happy to get another license and activate the new instance.  This might be the easiest thing to do.  Still not sure why the first instance is unable to load directory.  The circle just spins and spins after I press "L".

I have two machines running XXHE--both have worked fine so far.  One Mach III and one Mach II.  Each machine connected to a NOS1a G3 DAC.  Today all of a sudden XXHE running on the Mach II no longer loads the music directory.  XXHE on the Mach III works fine.  Both instances of XXHE point to the same directory.

I extracted the XXHE .rar again and installed another instance of XXHE on the Mach II.  Probably a bad idea, but wanted to try something.  The new instance of XXHE on the Mach II now loads the music directory BUT it is not activated.

Meanwhile the original instance of XXHE on the Mach II is activated but does not load the music directory.

Not sure why XXHE would not load music directory.  Anything I can try?

> Not that things will explode
Hahah, but Peter, you know i like things exploding.....   

There`s no 2nd NOS1 but i believe Anthony is keeping 1 or 2 spare NOS1`s in his attic for me just in case all goes up in smoke over here.

Since finally getting NOS1`a G3` going (special shout out to Ramesh and Anthony!) i simply had another silly thought - maybe try former fav Palladium cable again.

It`s ok the idea is scr*pped already. Forget it. Thank you (and for all!)

Meanwhile M3/L3/NOS1a/G3/Blaxius/top AC delivery - sounds KILLA man! 

All what Anthony said is correct.
Input impedance of the Orelo is IIRC around 80K Ohm.


Pete, this depends on what you actually are going to do with it. You suggest to try another fine (XLR) cable. But if this is really so - and nothing else, then this obviously won't work because your Orelo does not have balanced inputs.
If this is, however, about a 2nd NOS1 you possess and this is to be connected to something very else with balanced inputs, then fine in itself. But I am not so sure about this, and thus :

The answer is No. In whatever event you can't hope for anything good with a cable made for balanced purpose (your XLR) to behave in any good fashion if it is used as an RCA cable with a wrong impedance on top of it (not that RCA bears a formal impedance but alas).

I see another combination : you do have that 2nd NOS1 and want to try this with your fine XLR on your Orelos ... 
... forget it.
In that case you can leave the old BNC connection be - which you BTW can do anyway, but it will be a total mess electrically. Not that things will explode (all voltages will remain fine) but it will sound like a drag; The half of the XLR you will be using will be worse than a pair of shoe lashes as nothing in that cable will be made / be shielded etc. etc. for single ended operation.

The upside of this all will be that - also with your own original NOS1 you could do this, besides your BNC connection (this is what you asked about too). Thus, no harm done to anything for the BNC connection. But ...

Now this puzzle is pieced together somewhat for me, you won't even had the additionally required wires for a proper XLR connection (they are not hanging loose somewhere in there).
Lastly, electrically such a "faulty" connection has never been tried by me, and again I say the same : it will sound like a drag.
Side note (or not) : I recall a most simple desired combination of two pairs of outputs chosen from RCA, BNC and XLR (but I forgot which), and there was no way I could make that sounding right. The customer in order received an "impossible" from me. But that was judged with my ears and such. What you seem to head for is similar. Thus, what I am saying here is that because of your "illegal" XLR connection, your BNC will sound wrong too. "Will" ? I can't guarantee it.

Do notice please, that all what is impedance "draws" on the output. In this case this is quite directly D/A converter chips (with only one tiny resistor in the path) which have a relation among hem as well (2x 2 for one channel). Thus, draw on this wrongly (or untested) and the one will tear down the other (read : your half-XLR will draw on the other BNC, whether XLR is used or not (not used : means : open ended AKA not terminated). This is fine when it sounds fine. And if you really paid attention, you noticed that this drawing could be on the same chip- half, or the other (of one channel). With Single Ended one half is used for both outputs (like BNC + RCA). With XLR, both halves are used. With half-XLR maybe the other half should be used. LOL.

Try it and let us know ?
And have fun of course !

Peter

Change output impedance and output voltage will not change, but current will change.  Do you need more current from the NOS1a?  Nope, not into the Orelos nor into just about every preamp or amplifier on the planet.

In addition after checking Orelo wiring...

Orelo XLR
pin 2 = hot
pin 1 = ground
pin 3 = nothing

Fine to wire up the new 1x stereo NOS1 XLR sockets in same fashion?

Ok image of my NOS1 parallel wired channels

Should i leave existing wiring on the remaining stereo BNC sockets or should they now be disconnected and protected after swapping in the XLR sockets...
