Kenjit the SCM 11 are not as good as the SCM 19, there is a world of difference between the two speakers. The midrange woofer of the 19 is from the higher end models and the 11's are not.
You also can't judge hearing the B&W and Kef Ref 1 in different rooms with probably different gear.
We have the ATC SCM 11 and the SCM 19 in the same room as the Ref 1 and the Paradigm Persona B they all sound dramatically different.
As per the Harbeths we have had a pair of the Anniversary speakers trade in and they were very musical but very colored.
We have also heard the 30 and the 40's at shows, they are very musical loudspeakers and very colored stunning cabinets.
Depends on what you want our of your system and your musical tastes.
