$50k - $80k Budget…Opinions please.

Obvious idea is redo what you had !

Alternatively, do what I use here for mastering every style daily. Evolution MM3 +Exact (used $23,000 +Exact), Allnic Audio A-6000 linear tube amps (used $10,000). DA options are Berkley Audio Design Ser III, Bricasti M1 SE or Mytek Manhattan II (new: $12,000, 9000, 4500)

I buy used, depreciated, broken in, when possible !

After having been through a ton of gear (all the Harbeth and REL S series included), I am confident that nothing will outperform Fleetwood Sound DeVilles. For those of us that like a slightly warm presentation, they give you that musicality but don’t sacrifice detail or efficiency like the Harbeths. My DeVilles sound like my Harbeth 40.2 with the towels taken off! Retail is around $16-20k depending on the options you choose. 

For the rest of the system, a lot depends on what you want to focus on. My guess from your post is that you like a warmer sound, so I would pair the Fleetwoods with a Luxman integrated amplifier or some tubes you like. The other no brainer pairing with the Fleetwoods is either of the Technics GaN integrateds - honestly the $2800 ones sounds outstanding with those speakers. It is just one of those pairings that works super well. DAC is part of the amp itself, so all you need is a nice little streamer, a turntable (go with technics 1200G) and a couple cables. You’ll be all in for $30k or less and have a shockingly better system than most people with $80k systems. 

Tod a dac Thst all would like for $7k a great bargain  the T+A 200 dac

speakers  the New Sonus Faber Serafino G2 is $26k  and cannot be overlooked 

sounds as good as they look , integrated amp the New Gryphon 333 just atop of the iceberg .

Enthusiastic audiogoners here will start spinning you around with all sort of dream gears of their own.  This shows how much they care about you but it might not be a good thing because you will be overwhelmed.  Instead, it is suggested that you go to a reputable source like Stereophile and carefully study not only the measurements but also listening test experience.  Then screen out a few candidates and combination under your budget before presenting them to the audiogoners for advices.  This due diligence is a must.  Don't be lazy.

I fail to see why anyone would buy Macintosh. Abject mediocrity.

If your priority is to purchase US domestic products, buy Boulder. They wipe the floor with Mac.

Watching videos from Munich the Mac - Sonus Faber room was easily the worst.

But the Wolf Von Langa Son, with valve integrated amp, was reviewed by many as best in show, and falls squarely within your budget
