I have never heard a Sim gear but I have heard the Tannoy, Dynaudio and Primaluna. One thing is Dyns always come to their own when playing loud in a relatively larger room.
It is then that you kind of appreciate what they do best. But in a smaller room they are just okay. Tannoy on the other hand is very nice and should I say presents a tonally and timbrally more intimate realistic sound even in a smaller space and even at lower SPLs. Regardless of price I would assume that a good tube amp like Primaluna will always be very high in bringing out emotional content from the music, which your Sim may/would not do as well. Dyns driven by tubes is a hit or a miss, so you need to audition before you buy a tube amp for dyns.
I know Dyns can sound relatively cold and thick if not paired appropriately with electronics and I somehow have a feeling that is causing the issue in your case as well.
