rebuilding after a fire

Okay guys here's the story.   My house burned and I am rebuilding my system.  I'm now 60 years old and want this to be the last system.   Speakers were destroyed and per my insurance requirements I had to replace them to get repaid and have Goldenear Triton Ones with aon surrounds (4) and a super center XXl.  Low end is boosted by a Goldenear supersub xxl so speaker presence is not a problem.   currently using an Anthem D2 preamp and two Sunfire Theater Grands (5 channel 400 watt) in a 7.1 system.  Heres is what I need you for.   The Sunfires are old but to my ears still sound great.  The Anthem has been a good provider for years but should I upgrade amps and pre amp.    Currently using a EAT E Flat turntable with an ortoforn black cartridge.   I listen to a lot of jazz and classical as well as blues and 60 through 70s rock.     Should I upgrade the amps and preamp and if so with what.  I still have some insurance money left and I like separates to avoid crosstalk. Parasound and pass have been recommended but Pass Labs is expensive.    So are the Sunfires sufficient and if not what do you recommend.   Second what theater preamp which is also good for music.

Thanks for all suggestions.
