Nick,

In my proto-box there's currently still the switch hanging around that can add ~240mA per channel (I think I mentioned it in between the lines in the first post). So what I planned at some stage, is adding more current by means of, say, two switches (engage them both and the current is double the native). But it did not sound well. Not for me ! But I never thought of a situation like yours, where indeed it would be so that "double the drive" implies double the required current, all else being equal (read : if in my case and one 50K input impedance amp, the ~500mA is the best, then with two amps 1A should be required - well, sort of because the length of the interlink stays the same). So while I ditched the switches, I shouldn't ...

The additionally attached current ("chips") are only switched in the output signal path and I think/claim this is allowed at this higher level (of current). Measurement really shows no difference at flipping the switch (while it thus surely is audible). Side note (or not) : In my situation this additional current sounds chaotic, but this is not because of the switch; it already does with the chip nicely on the PCB like the others. Still, I can't judge the switch for that merit (of "switch").

Anyway ... thinking more inputs and what not it is not so difficult to again think "switches" (in the case). And if I do what I planned, then 2 switches plus electronics supplying the current, will cost 150 more for SE (300 for Balanced). It goes like this :

One switch can serve two "channels" and a channel is regarded one SE channel. Thus, stereo RCA (= SE, Single Ended) requires one double pole switch (think power switch sized) to attach one step of more current; with Balanced, the one switch would attach one functional channel (like the left channel) for both plus and minus of the differential channel. So it requires two switches to attach current for the left and right channel for one step of more current.
Thus two steps require 4 switches.

The switches would be at the outside of the case, reachable at any time without lifting the lid.

A #2 XLR type please for me Peter.

One question, does the B'ASS have unity (or less ) gain ?

My NOS1a is driving 8 gain clones from its balanced outputs so the current capacity of the B'ASS would be very welcome but very loud volume is -34 db in XX so extra gain would not be a good thing for my system.

Regards,
Nick.

I would say this though. In my opinion, fundamentally, your approach is wrong, because instead of proceeding in a holistic fashion based on a deep understanding of how this very complex and audio unfriendly environment that is the personal computer works, you approach the "audio pc" in a random, piecemeal manner, that will ultimately paper over the cracks and not solve the deep-seated issues. Unfortunately, I think that everyone here has no choice but adopt this haphasard method. It is clearly not unscientific because as with many fields of knowledge significant progress can be made in this way. But it is not ideal.

Blarr blarr blarr....

...So what is my point? Sometime we audio people forget that in buying products from dealers/distributors/manufacturers, we forget that if you tear down all the hullabaloo about a change in settings that means your mother-in-law can shimmy away to "dance music" (what the hell is that anyways? - I thought a set of Bose speakers and two huge subs would do the job) in the kitchen, presumably this being the metaphysical g-spot sweet spot where the system is at its most resolving...you are left with real products which deliver day in day out, and if you run in difficulty, there is someone you can easily turn to.

Thanks Peter, point taken    I will do the reinstall, fingers crossed

Kind regards,

Nick.

Nick, I softly tried to tell you that you may have problems with "sequences". My methanol and key example apparently does not help.

Install W10 properly and try again. Period.

I hope this helps ...
Peter
