I think first you need to find if the soft bass is from the speakers or the amp. You could try to borrow or home-demo a high-power (wattage) solid state amp with your speakers to see if that improves the bass. If it does then a new amp would help. If it does not, then it's probably the speakers themselves (or it could be your room acoustic). Most Dynaudio speakers tend to have warm and sort of boomy bass especially those big floor standers. Almost everyone who has Dyn would agree. Even the smaller stand-mount have somewhat overly warm bass. A guy just came over to my house to audition a CD player said he had a pair of Dyn 52SE edition but the bass was too warm so he finally sold it.
Anyway, make sure it's the amp before you committ to buying one.
Once in awhile, there are a couple of VTL 200W amp that come up here at Audiogon you can try. It is amazing that those old tube amps can sound a lot better than the so called modern solid stage amps. I had a chance to listen to a Electro-companiet amp with my setup and there was just no comparision considering the VTL amp I have was made 15 - 20 years ago.
