I'm Alex.
I replaced the 7,000uF Mallory computer grade caps in my bridged Crowns with 22,000uF Visahay BHC's from Farnell (I don't have a trade account and over £20 is free postage). No turn on surges that I can see and no other troubles at all. The Crowns are so carefully VI limited all over (due to their cold running role in studios) that any sonic advantage in these caps is probably well hidden. The Quad 405 with mk2 current limiting or Dada replacement boards may be more able to justify the expense, although £12 - £15 each or so isn't expensive IMO for low ESR ones.
Tear down these walls; Cut the ties that held me
Crying out at the top of my voice; Tell me now if you can hear me
