Detlov,
Many lower-powered tube amps offer a great sense of dynamic contrasts when used with speakers of high enough efficiency (especially mid-bass through lower treble). Some of what makes them sound more dynamic is their tendency to bloat the midbass somewhat. I think that most properly designed modern SS amps with adequate power supplies can and do compare well with the best tube designs. And, if your speakers have very low bass capability SS may rule that subterranian region below that bouncey mid-bass area that tubes seem to do so nicely.
