What would it be? Given your existing equipment; what you could choose; a Cost-no-Object Phono-Amp, a vintage tube amp from the 70's, or some high-end cables?
Having said that...I would choose the "Sonus Faber" speaker. It looks awesome and would dominate my living room like an 800 pound gorilla...and sound stunning. Powering this speaker with my NAD receiver might be a crime against sound production; but this is my choice!
What are your choices?
