the cart or the horse?

I would keep the speakers and simplify everything else. One voicing

Personally, I’d buy a used integrated - ideally something with DAC on plug-in card

With those speakers, you can be flexible on power specs

+ Used PrimaLuna (Prologue 1?)

+ Budget is almost at the very best Marantz integrated (used)

+ Used NAD, and one simplifies things even further (you aren’t far from an M33, certainly an M10) - they all act as streamers. DIRAC might contribute to listening experience in a room that size

+ With your speakers, I think the suggestion of the Luxman SQ-N150 is a lot of fun, albeit you’ll need an external DAC

+ I like the Hegel 95 suggestion above

That gives you a range of tube & ss to consider, and all of those components will last for a long time (and can be resold)

All the above subject to listening preference, but s/b easy to audition because brands are widespread

Save a little more & think about some inexpensive room treatments, if anything obvious jumps out to you

Let us know what you decide to do!

Have a great day

@onebean  - the old stuff is always fun.  I am actually running a factory refurbished ‘93 Mc pre on my main rig, in part because its so simple I figure they couldn’t have messed it up. Still have my father’s 40 year old Luxman gear and it works just fine (would of course benefit from a refurbishing)

Are there specific vintage dealers you could recommend for @wavendon , and all of us? Would be good to know dealers who do a good job with vintage

I have worked with Audio Classics and had good experiences, but that’s mostly Mc focused

There is SkyFi, but I’ve never worked with them - just note that they do vintage and refurbishing/restoration
