The “audiophile” brand components will obviously drive up the cost a huge amount though.

Heres some quotes/estimates with decent parts (price for one item):
6x LM3886 $5.40
2x RCA jack ~$2
4x binding post ~$2
10x 1200uF 50V low esr $1.33
2x 47000uF 40V $14
2x 15uF Poly 400V $8
6x 0.2ohm 2W 1% $2
1x 500VA Toroidal $110 (can source cheaper on ebay, or use a standard core).
xx other smd components, caps, switches, jacks etc. ~$70+
2x heatsink $40 (or less surplus/used)
1x case: price unknown, you can gut something used for next to nothing, or spend hundreds.
4x double sided PCBs: maybe 50sq inches total, $100 would get you enough boards for two amps

Total? approx $500. More if you bought a case and fancier parts, less depending on parts quality.

Or if you are like me you have most of this stuff laying around… :P

He mentioned that an audiophile equipment manufacturer had asked them to make a batch that was gold-plated (so they'd look a little less out-of-place driving a $n,000 amp, no doubt).

If you are interested in buying any of their kits, they appear to ship to other countries. I'm sure the readers who understand mandarin and myself would be happy to help you place an order.
