Nice amps! With the exception that it usually means the loss of a family member, that’s a great inheritance. 😎
I’d at least be pondering speakers that allow the option of some hybrid bi-amping with tubes on the lower mids and up if possible, and SS on the woofers. Even with good passive crossovers it can still highlight the strengths of both classes of amps. Sorry I don’t have any particular models that are available in mind.
