I ended up getting the Buchardt A10 bookshelf speakers which was about $4k (pre-order price). All these speakers were going in my living room so looks played a role in my choice. I was not too enamored with the KH120ii looks for the living room. I really liked the idea of streaming straight to the speakers, going wireless, having different EQ and Masters tuning options, room correction, quality components, good bass extension, good resale value and the all natural wood cabinets.
I like the A10 more then the KH120ii overall, but do wish for more volume. I'm going to still plan to get larger speakers in the future, but for now all round the A10 is a good speaker to chill out and enjoy the music at low and moderate volumes. Pre-amp, DAC etc. in a while now

Its super hot these days and my huge A biased A/B amp doubles as a radiator, so don't miss it right now.
I'm still curious about the KH150, but I think I will go even bigger next purchase, at least KH310ii so I can party more

Going from online measurements I expect the KH150 to measure better then the A10, even in bass, but waiting for more A10 data.
