I am definitely open to persuasion and other points of view, including a "don't waste your money an accept that you are just a bedroom noodler"! Which is of course the point of asking my friends here
I think if I am buying an amp then I want a clear upgrade from my Blackstar which is pretty good for the money (it's about a £400 amp). Otherwise, it might make more sense to spend my £500 voucher on some premium effects -- the OE Trem, say, or that bonkers Chase Bliss one with the motorised sliders -- or even another guitar. And of course I already have the OE Revival which does a pretty decent job of a whole range of classic amp tones and works like an amp front panel in terms of going FROM clean to driven with the gain knob. Mostly my playing since getting that the OE has been just Tumnus (as a dirty boost) > OE > Fender Reverb and/or Fender Tremolo.
(Although as an aside I am intrigued by the idea of really lovely sounding amp and using the OE Revival feature to blend dry / wet sounds)
The Vox hand wired range can get pricey as well depending on which speaker you want, although the AC15 with the a Greenback speaker like the Morgan is £799 which is a significant difference. It also puts the cost of hand wired in perspective as well: "normal" AC15 w/ Warehouse G12C = £695, hand wired / turrent mount version = £1299. With my £500 voucher an amp in that range would be a very affordable upgrade on my Blackstar.

The other point I would make is that this is really a gift from my employer to mark 10 years of my life in what will almost certainly be my last job before I stop working. Getting a nice amp I'll have until I pass it on to my nephew seems more fitting to mark that than just buying a another pedal.
PS I am pretty sure I am going to sell a lot of my pedals once i get round to it as most of them are already unused.
