Thanks @jerrybj, appreciate the update and info. I'm also in the UK.
To complement the FI-33 NCF(R) socket, I replaced the Puritan Classic+ C19 connector and mains plug with
Oyaide C-237 Rhodium/Silver plated 20A IEC plug, C19
Furutech FI-1363R NCF UK Mains Plug (90 degree)
respectively.
The Oyaide is also a nice piece and far less expensive than the equivalent Furutech FI-32, however the Furutech parts are of better construction.
Apologies to the OP for the digression ...what's your thoughts on the EtherRegen? I've read mixed reports.
I've not come across the Acoustic Revive part specifically, will look it up.
