Upgrade help: Luxman and McIntosh.

This is my first here although I have been reading this forum for several years and and immensely thankful for several knowledgeable posters.

Current system is Bluesound Node 2i >> Schiit Bifrost2 >> Arcam A75 Plus >> Totem Sttaf. 

Musical interests are Jazz, Blues, Classical and Vocals(mostly female) and listen at low to moderate volume.

I have had Arcam/Totem combination for over fifteen years and have been happy but recently caught the upgrade bug, not because my system is unsatisfactory but rather because of the thought that I might be missing something.

After some research I have narrowed my selection to  Luxman L-507uxii with Spendor D7.2 or McIntosh MA352 with Dynaudio Contour 30i.

I think I can live with either of the speakers although I am leaning more towards the Spendors.

I would appreciate any comments/advice from someone who has listened to the specific models or experiance with products from both companies.

Thanks in advance.
