You might want to look into the NHT Xd system. Their whole raison
d'etre is low distortion; system specs <0.00315% THD, which equates to
something like -130dB.

They don't sound too bad either.

This is true. OTOH this NHT system is the first of a new wave of speakers with
dedicated dsp control which may be the next breakthrough technology advance.
