Speaker Recommendations

I currently have a set of Gunned MMGs, but I’m thinking about trying out a different set of speakers. What do you think would go well with the components listed below? I mostly listen to rock, jazz, and bluegrass. My budget would be no more than $3k and I’m not opposed to buying used speakers. My amp is class D. My room is 14x18.

Audio Mirror Tubadour IV SE DAC

Don Sachs Model 2 Tube preamp

D-Sonic m3a-1200s amp


Fyne Audio 501SP (used), Zu Audio (Soul 6, DW6 Dirty Weekend, Union Supreme), Fritz, Rogers/Falcon/Spendor LS3/5A.....all easy to drive

Can't go wrong with the Atalante 3 monitors. I have them and will never part with them unless I get a bigger space. Then I'll go for the Atalante 5 model. 

All the best,
