Hmm.. that is still a job to do with mine actually. I can solder but... wow... them little things are really small.

Hi Marco, are the Z-foil's the same as Vishay foils? (which I think they are)...Lol - job done!
It was upgrading the resistors in the IQ-Audio DAC, as Dunc outlined, which have now been fitted with Z-Foils... All I can say is
It's a royal pain in the ass though, removing the existing surface-mount resistors, which are not much bigger than a pin head, and trying to solder-in standard sized ones (with tails) in their place, without at the same time lifting the track on the PCB, with the heat of the soldering iron!!
Not a job for the fainthearted, and certainly not something I'd recommend for anyone but the most able and confident at that type of task. Worth it, however, sonically? You betcha!
Marco.
FYI I was having my MDAC upgraded by JW a couple of years back to the then latest upgrade of L2 (I've lost track of where he is now on his PFM thread). Whilst he had my DAC he discovered the benefits of the foil resistors...and offered 2 additional upgrade paths...
One known as 'Toy' (after the forum user who first went for it), using 4 foil resistors in the most important areas (where I can't recall)
The other known as 'Fusion', using about 32 foil resistors...
At £16 a pop for the resistors I went for the 1st option...
As my IQaudioPiDAC is in a case (kitchen duties), I doubt I'd be able to shoehorn them in, even with the aid of a professional
EDIT; Looks like they were used in the analogue signal path, so perhaps not the same as your mod...

All sorted now with the Z-Foil upgrade and sounding great !! I would attach a photo if i knew how.

Looking good, Terry.
I need to find someone to do mine me thinks.
Does anyone know if you can power the PI/IQAudio DAC+ another way rather than the micro USB socket? I'm looking at recasing mine and wondered if there is another way. I have read that you can power the pi via the GIPO pins but not sure if they are available once the dac board is mounted.
Thanks

Oh my god! There's nothing wrong with the bidet is there?
“Nothing discloses real character like the use of power. It is easy for the weak to be gentle. Most people can bear adversity. But if you wish to know what a man really is, give him power. This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".
“You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”
"You don't have free will. You have the appearance of free will.”
“There's a war out there, old friend. A world war. And it's not about who's got the most bullets. It's about who controls the information. What we see and hear, how we work, what we think... it's all about the information!”
