'Analog Dinosaur' succumbs to the joys of FBA : enter Raspberry Pi 2/IQ-Audio DAC+!!

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

I know, theres no way i could do that !! Hopefully my neighbour is going to take them to his work tomorrow, so fingers crossed!!

Unfortunately my neighbor didn't have any success - any takers ?

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!! :doh:

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! :)

Hi Marco, are the Z-foil's the same as Vishay foils? (which I think they are)...

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.

Thanks for the heads up on how to upload the photo guys!!

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
