Not dissimilar from you, I have an 11x18’ room with 9’ ceilings, and a wife to keep happy. The aesthetics are very important to both of us.
We have Zu Druids. Mark V, bought new in 2015 for 7k. I believe the nee revision extends lower and is up to $10k. Which leaves you with 10k leftover for a vanguard fund.
My wife and I are both very happy with the aesthetics and sound. (BTW, she’ll never say any improvements to the signal chain are happening, but she’ll wander into the room and sit and listen when there has been one).
I Demo’d at a show in ‘before times’ when we could still attend audio shows safely. I heard their little brother, The Zu Soul Supreme, at the NYAS. They were the first thing I heard after a very expensive Vandersteen room. And the Zus, powered by a Peachtree nova, just had me leaving the room with a feeling of ease that I didn’t get from the Vandersteens.
I’m using a restored solid state class A integrated, Pioneer A-91D, with its integrated DAC, spinning mostly CDs, sometimes SACDs, sometimes wax, and we watch a lot of movies on our 2 channel system. Zu prefers a lower damming factor. I tried a more expensive amplifier, designed to measure well, the Sony TA-N77es (I’m a vintage 🇯🇵 person clearly) and the Pioneer went back into the chain as it lowers the frequency extension and helps provide a deeper image. I have a very linear midrange.
Lots of people will recommend Harbeth and I will strongly second them. I’m saving for SHL5+’s to replace my JBL L100s in my bedroom. The M40 series are shockingly lifelike.
Final plug, if you’re interested in the active route, check out Kii threes. One of the few presentations I’ve heard better than Harbeth.
