N802's are not inefficient. They are specified at 90db 1W and 1 meter. They are however, very sensitive to the amplifier driving them and cabling. It is all too easy to end up with a lean, bright sound.
The W4S ST500 is an excellent partner along with a decent tube preamp. A VAC Phi 110 produced excellent bass also. The tube amps will produce a fuller sounding bass with less impact. The VAC pa100 sounds real entertaining with jazz.
The N802's are not the last word in bass definition or tunefulness but one can certainly achieve a good spectral balance and plenty of bass with the right setup.
