that is your system after two years?! i'm impressed, well done. your speakers are quite sensitive as well, with a friendly impedance curve, so perhaps it's the 'voice' of your speakers you're not happy with.
instead of going SS by default, you could also go with more sensitive speakers, or equally sensitive speakers with more of the traits you are looking for. that, and also i'd try your system along the long wall just to see what happens.
your whole system seems quite high end and balanced as it is already, so any changes will be merely adjusting the personality of the sound. you should be able to get the sound you want without spending too much more. unless of course you want to go HIGHER end, in which case, have fun... =)
