Did my research on coupling capacitors and ordered a matched pair of V-Cap CuTF 0.22uf 600VDC from HifiCollective in the UK for 300 GBP.

Availability seems to be more problematic with Duelund. The Cast DC copper 0.22uf 630VDC was a 6 month wait at HifiCollective and wasn’t stocked by PartsConnexion.
The Cast DC silver version was only in stock at PartsConnexion and would have cost about 800 GBP with import taxes in the UK.
There is a Cast DC copper pair on eBay China but the seller has no feedback and delivery was 3-4 months.

Might be worth waiting for or could be a fake. Hard to tell. Decided not to take the risk.
Apparently, Frederick Duelund made this rectangular pair himself. Could be amazing and better than current production but I wasn’t willing to take the risk on this either. The higher 0.47uf would be fine as far as I could tell, the VDC is the key metric to match at 600-700.

I understand V-Caps sound better out of the box than Duelunds and the upgrade benefit is skewed slightly more towards clarity than musicality.
