Just to further counter the inexperience based misinformation above, here is what Origin Live has to say about the relevance of compliance matching:
Cartridge compliance calculations are an overrated simplification of complex problems. For example the vertical compliance is sometimes different to the horizontal compliance but this is not stated. As far as compliance issues go – Origin Live and many dealers find theory bears little or no relation to reality. This view is now increasingly held. There are too many surprising experiences where theoretical optimums mis-track and theoretical mismatches track perfectly.

Its not that what they're telling you is wrong. Their harmonic resonance theory is perfectly valid... theory. Its just that this is the real world.
