Hi all, i would like to hear someones opinion on this. At the moment my system consists of a naim AV2 fed to a three channel amp and for stereo is then fed to a linn, naim six pack isobarik system, rears are shiniann super elfs speakers and the centre is a naim axent speaker and the tv is a pioneer LX5090. The sub is a M&K MX350 and i was wondering to add another to the system. The manual says by adding another sub improves dynamics and i would imagine the base would be flow more easily, what do you think, good idea or over kill ?....thanks.
