The old MBs were HORRIBLE to position and took 200-300 hours to break in. Whole line has been completely redesigned. The MB1 B reflects the new designers approach which was all about making them more approachable and easier to live with.
They explicitly state the new speakers break in within 100 hours and are designed so that placement is extremely flexible and they can even be placed close to the wall. 100 hours is nothing in terms of break-in time and can be easily achieved within 30 days.
I find Scansonics to be pretty natural sounding. The detail is achieved through quality of driver rather than increasing the volume on the tweeter. I personally prefer a slightly forward sound profile in a speaker and these are warmer than my optimal taste. I am not sure if they are dead neutral but they are definitely not bright, nor are they dark or laid back.
The thing about Scansonics and all Raidho products is the soundstage and imaging. That is what makes them special.
I am waiting for my freight company to schedule an appointment to drop these off as they should clear customs today. As I said above, 30 day in-home trial if you want to give them a try. If you want, I will also take your Veneres on trade to make it easier but if you are unhappy with the Scasonics, could be a challenge if the Veneres have been sold if you want to return, etc...
