Well, its up to anyone to choose the parts to populate the boards with. If on a budget, then select std components. Want the best, then choose that. Its a free world 
On my end, for through hole resistors, I will use Yageo MF/MFR, but initially had planed to redesign the boards so I could use Panasonic ERA smt resistors. A component GB could be a hit and miss since there are so many minds wanting to add to the pile of "what's good and not".
For the MUSES chips, a GB makes total sense. We could probably include some other IC's as well... just a thought.

Hi All,
I missed probably the last 5 pages on the forum, I am going to check if anything for me.
Then Fencki I consider this closed now, 2 people did not answered but it is fine, there will be 1~2 spare kit that I am certain will find a buyer.
I am about (in a couple of days, I miss 4 gerbers) to give the updated cost with shipping and everything for each buyer then pay & order.
Shipping cost calculation is done.
Pars could you kindly resend me your gerbers for the encoder to add the costs in?
Also one possible suggestion would be to add on your PCB the hardware debounce components that are not on the control board PCB if we ever move to a dual encoder control of the machine.
I am doing debounce in software but adding the filter does not hurt (2R and 1C).
If not possible then no problem and all will add theses components directly on the pins or not depends on them.

We can check this later on Pars but I don't believe it is possible with just a modification of the control software.
You will need to cut track on the PCB and reroute them.
Nice transfos, this is the company I used for my UP grade, very good quality.
Did you guys started to heat up your soldering irons ?
In the meantime in am taking my “dog” out for a walk
That's a very nice hobby too
Ok so here it could be a modification with a couple of flying wires and reusing the filters on the SW1 to SW6 that won't be used if I add another encoder.
So in the end not necessarily needed Pars, let me check in the coming days to find the best approach for the one willing to use later on a dual encoder vs. SW1 to SW6 + an encoder.
To comment on the position of the UGS vs the buffer, it is a matter of taste as Eric was saying and listening tests will tell.
I agree on the other hand that the Muse has enough headroom for the audio signal that should be in any case at 2VRMS unbalanced coming from standards equipment.
Thanks Alex, and that matches my assumption from looking at the schematics.
That functionality is pretty common in a preamp, but I hadn't seen it mentioned in the homecinema French thread for the Muse preamp (or for the AI version). I could have missed it however.
You are welcome Chris. One solution could be in your case to add a pair of RCA/XLR L/R mounted on the rear panel and directly wired to the bypass relay input so that they are always connected to the selected input source.
I will probably be able to make a FW for this. My DAC is already using this control scheme. We will loose a couple of shortcuts with the existing long press but not a major issue. I like as well the look of the dual encoder design.
fencki is right, it’s easier for us mortals to solve it with a 2nd encoder than with the push buttons... i mean mechanically. Beside this a bit of symmetry is always pleasant to the eyes not to mention that also the main circuit of the preamp is focused around symmetry.
Thanks Alex for accepting this!

I am very committed too, I just need my days to be longer than 24h 
Anyway I finally have all the Gerbers, requested the quotation and I am about to provide the exact cost to everyone.
From the 70$ first quote without any PSU PCB (options) / encoder PCB neither shipping we are now a bit above 100$ for typically a full kit with 2 additional options (total 18 PCB).
The shipping costs to add vary between 25 to 40$ for EMS 4-5 days according to destination, closer to Taiwan being cheaper.
I need to check the price of the packing material.
I will work on panelization to see if I can optimize more.
You have the overall picture, the full details to come latest this week end and then PayPal time (finally).
