It is quite a bit more money. Do you really need the die cast woofers? Ian said there is no difference in sq so I didn't get them on my LFR's.
Anyway, what I can say is that they're excellent. Whether they're really more than two grand better than the M80's is very subjective. I think you can notice the slightly deeper bass of the LFR's but it is not a huge difference.
The rear firing drivers combined with the DSP do certainly add sonething. Depending on the source material, the difference can be anything from very subtle to astonishing! However, only you can really decide if they'll be worth it.
Perhaps you should check with Axiom to see if any have found a home out near you yet.
