Should I build a ProtoDAC?

[MJR42]

Thanks @hifinet, I’m going to price out my options. The US/CAN$ exchange rate is what’s killing me, so I’ll see what AliExpress can do for me.

Just to be sure, when you list a resistor as “420R” does that mean 420 ohms?

I’m finding foil resistors at https://www.mouser.ca/c/passive-componen...ough-hole/ (in Canadian $$) - these are what you’re recommending for high performance, right? I’m assuming you didn’t find a better option at AliExpress or eBay, is that correct?

How would a site like this identify “audio quality” capacitors? Should I just go by the brand/part names you listed in the original post?

Your help is appreciated. I have a basic experience with electronic circuits, but not with audio electronics.
