Floorstander reco given a few criteria...

Ok, that's fair. You've piqued my interest tho. Let's say the 3k is spread across the speakers and a different amp - and say there is up to an extra grand if it would make a meaningful difference. What's that combo look like and do you think it would sound notably better than the sonos plus the spendor or wharfedales?

OP, it seems like you’ve opened up a lot of possibilities by saying $4k over floorstanders and an amp. (I think that’s the gist.).

I like jjss49’s suggestions (I’ve heard Spendor; Wharfedale also sounds like a good fit). You might also consider Quicksilver, Totem, Focal:

Separate Preamp and amp ($2300)

Floorstander: ($1415)

or these ($2100)

Integrated amp: new, this integrated is still a great deal: ($2k)

You could pair it with these, used and be a bit closer to $5k:

Or these and hit closer to (4k, total):

Thinking a bit more now....I bet the Quicksilver + Spendors + your phono setup would sound really lovely. You could tube roll a bit to find the sound that suits your taste, music, and room. Search for Quicksilver in these forums -- they bat pretty close to 1000 with folks.
