@grannyring thanks for the feedback on the Vcap odams. Yes, I agree with you that they have an open and a bit bold character which may not be suitable for this speaker in particular.
I am making an assumption these speakers don’t currently have a top tier copper foil cap in them. If they do, then wonderful and leave them be
The Nenuphar is a full range single driver speaker with no crossover. Amp straight to the driver.
