Speakers that scale

I’m currently in between speakers, and despite my best efforts to rely on headphones to carry me through the 6 week + waiting period for the build, I ended up shopping my favorite local HIFI shop. Happened upon some Sonus Faber Lumina III’s for an outstanding price. 
 

I placed them in my current 2-channel rig with LTA preamp, and Pass power amp this weekend. As a previous SF owner I knew what to expect, however I have to say the old cliché of “punching above its weight” comes to mind. Perhaps it’s being without speakers for a few weeks. But it reminds me of other speakers I’ve put in my HIFI rig that scaled to the equipment. The ubiquitous KEF LS50 is one. The SF lumina is another. 

Perhaps an interesting discussion topic, what other speakers scale up to “better equipment?” Meaning most of us follow a rule that your speakers and amps likely would account for the majority of the budget for a system. But being you have a reference Amp, Source etc. what other speakers can play with higher priced or higher end gear?
