I must admit that after searching on this topic I'm still a little hazy as to what if any consensus was generated on this topic. Would it be advantageous to use a outboard bass management solution such as the Outlaw ICBM of M&K BMC Mini of LFE-4? The unit would be connected to a Preamp/Processor which does not offer bass management on its multi-channel inputs. The literature for the 2900 states that it offers on board bass management for both SACD and DVD-A, but I would love to hear some real world experience from members using it with and without the outboard solution. Thanks to all.
