I had a quick look at my Digikey account and I really can't see what's happened about the parts lists? Sorry about that.
Hi Ray,
When the link I posted earlier is clicked, nothing gets added to the cart. Not sure why that is.

Good day and happy new year to everyone, does anyone have any PCBs available to sell?
Eh!!?😡
I seem to have accidentally deleted the links to the digikey carts, here they are again;

I wonder whether the basket shares are time limited?.
Anyway, good to see you're picking this project up, I'm interested to hear about your results with the output arrangement you plan to use.
Sorry but I was wrong to quote you, I wanted to ask you if any PCBs were available for sale to build the dac
Hi. all of the group buy PCBs were sold but I've not heard from most of the subscribers about any progress with their projects so perhaps you will be lucky and someone will have changed their mind.
You misunderstand, I was mad with myself for deleting the digikey links - no problem with you quoting me at all. Anyway, I've just posted about the PCBs.
If I wanted to create my pcbs myself, having them printed by some company, would the price be high? Are the print files available?
Hi again Tix. I just checked on PCBWay and a repeat order for a minimum quantity of five PCBs will cost around $450US - these are large PCBs and are four-layer with a custom layer stack that is an important part of Marcel's design, hence the cost.
If you're still interested in this project I suggest you check out the first post, which contains lots of useful information - if you haven't already done so, of course.

Will let you know how it goes. Yes, there could be a time limit. The original URL for the SMT parts cart worked okay; it was just the cart for the thru-hole components that wasn't.
Chances are that Eurocircuits is cheaper when you need only one PCB. They have no minimum order quantity and the stack-up needed for the main board of the valve DAC is their default stack-up. I just checked their online price calculator and found these values:
Euro 256.92 including VAT, raw-DSD version
Euro 328.74 including VAT, original version
For comparison, $ 450 is roughly euro 368.
Two PCBs for the raw-DSD version already cost euro 418.35 including VAT, euro 345.74 excluding VAT at Eurocircuits, and five cost euro 573.54 including VAT, euro 474 excluding VAT.

Is there a BOM for the full version of the Valve DAC? I have one for the DSD-only variant, but wasn't sure how much crossover there was on parts.
There is only a list of components and footprints in .csv format for the main PCB. It is hidden in the first of the two .zip archives on the Linear Audio site.

Mind you, the reconstruction filters are not included, only the connectors for the FPGA module are in the list and not the module itself, and the power supply transformer or transformers are also nowhere to be found.

OK, so commas are treated as field separators and semicolons are not. Does it get any better when you take the attachment and rename its extension from .txt to .csv?
Thank you! I was able to import to Excel and specify that the comma is the separator. Now it looks like your screen shot, except the part designations (like R66, R58, etc) are not separated by commas, but that doesn't matter.
I'm going to start making a Mouser BOM based on this list.
