What The ear.net posted about it with their price guess:

$12K is exactly what I thought it would cost. Much easier pill to swallow than the alternative, if you have a DAVE. I may just wait on this instead of spending $30k on a different dac.

They mentioned £12k (pounds)
Thats $15,24k on current exchange rate..
I was hoping Chord would treat them equally. Still $15k is much better than $30K 🤷‍♂️ :pill:

Will be a loong time before 2nd hands hit the market.. but im not buying unheard so next year probably

Unfortunately, even that calculation does not take into consideration the addition of import duty into the USA 😔

Considering the double chassis I'd been expecting £20K+ but hoping it'd be less
And then there’s the feet. Do you think the power supply will be available separately? Will it be possible to buy the Scaler bit and use a lesser power supply, or even batteries, until you can afford the fancy power-supply? After all, the M Scaler used a cheap PSU which was supposed to be perfect. As were batteries.

Of course, you can use any of the widely available 1V 75A power supplies😂
Also good luck to the lps fans😜
Ok straight answer: My bet is 100% not possible this time.

I think the PSU outputs a higher voltage and each FPGA has its own DC-DC converter to 1v, just like the current Mscaler.

I can’t find it anymore, but Rob spoke of a psu that he built that is able to deliver 80A at 1V. I would bet it is this one. Also 75A at 5V would be 375W, that’s too much.

75A could never run through those thin wires he used on the proto.. 1mm2 wires would get burning hot.

That is also what I thought. Maybe that is why the listening sessions where so short.
„Wait a minute, it’s smoking again“😄
I’m just quoting what Rob said. Maybe he meant 75W and just misspoke.

Remember that the original MScaler used 1V at 10A for the core, so multiply that by 5 for the quartet, and you get nearer to the ballpark of the 80A.
