I had the original Numa and really liked the sound, close to my old C3/ leslie 145, but quality was an issue.
When Viscount Legend came out I bought it but returned it, cause the sound and sim was in no way close to what I was searchin for.
Later on I tried the Legend again, with the latest update OS 1.6, but still not what I was after.
Then I was lucky to get a KeyB Duo MK2, same "engine" as the Numa, but built like a tank and two manuals.
To my ears keyclick and crosstalk are essential to the overall sound of the KeyB and the way they (together with the C/V) blend into the sim is just great!
The soundmemory of my C3/ 145 says KeyB Duo MK2 is as close as a clone can get (for me).
I´ve tried a lot of different speakers to get the livesound right and now I´m OK with this:
KeyB and Viscount Physis 3 -> Peavey PV6 mixer -> DigiTech RP360 effect -> QSC GX7 poweramp -> two Kustom 12" guitar cabinets fitted with 15" Fane Sovereign fullrange speakers.
Today I´m happy with this rig, tomorrow never knows!
