High value, giant killer speakers?

My reference and last speaker is Philharmonic-3 fro Philharmonic Audio. Just my ears :)

PS - worked through Golden Ear Triton 7s, Triangle Celius 202, My own custom built (by me) 4-way towers, my own custom built 3-way towers, Klipsch RPFs. Was going for B&W 802s but fell in love with the Philharmonic-3. Cabinets by Jim Salk, flamed maple in rose red.

If you have a large room, especially if you listen at high levels, the ATCscm 300 tower speakers are hard to beat, 40k including matching power power amps. My system is simple high end, Jays Audio cdt3mk2 cd transport into Tidal  Preos preamp/dac. Simple, and simply stunning.

I think the Kii Three has a very competitive price since it contains an amp and a dac.

That said we as a community probably have too too many ideas of what a system should sound like to really have generic "gigant killers"

Eminent Technology LFT8 either A or B.  I prefer A cause I am a devoted dipole fan. ET's are still available new in theory but the wait is loooong. Magnepan's were my first love and the 1.7 and bigger are must audition speakers. Gee, there's that dipole thing again.  The recommendation to "save up, get what you want used and stay off the merry-go-round" is words for the wise.  Your worst problem will be getting to hear a particular speaker in your area.
