I'm wondering folks what are the parts required to build you own PuriFi amplifier. I was really interested in the VTV but then they are out of stock on the stereo version and won't reply to contact request on their websites. So I might want to just build one myself.
Thanks.
It looks like you can buy them directly right here:

Though I have not tried doing so myself. You'll also need a SMPS like this one (and know how to connect it correctly):

And of course you'll need to know exactly what you're doing to ensure it's safe in terms of AC power, grounding, heat / ventilation, correct heat sink mounting and spacing of electronics to safety specs, etc., and that you don't make any subtle mistakes that messes with the signal due to EMF interference, creates an unsafe product due to bad AC wiring that could kill you even though it seems to work just fine until you get shocked, etc. etc. You'll probably also want to buy a signal analyzer if you don't have one to be able to validate it is performing well without any unexpected flaws or spurious signals, etc. etc.
Or you could just buy from a manufacturer who does this all for you . Just be aware of the discussion above about the varying quality of different manufacturers out there. If you already have all the electrical engineering knowledge and tooling you need though, by all means -- DIY looks like the most cost-effective approach to get quality results (as long as you do know exactly what you're doing, which may be more subtle to get right than you think, as evidenced by mistakes made by most other manufacturers).
