Hi Fullrun. I owned Concertinos for almost two years and enjoyed them greatly sitting on top of a pair of Lovan Imperial 2900 stands.
The Imperial 2900s are 29" tall with a single slim, rectangular post that I filled with steel shot. They have a small top plate for small mini monitors and gold capped adjustable spiked footing. These stands were featured in Vienna Acoustics ads in the past and are very elegant looking. I bought mine through Audio Advisor for less than the $280 retail price.
My Concertinos are gone, but the Lovans remain. Now with ProAcs sitting on them.
Good luck.
