Meridian G68 and MiniDSP

Use a miniDSP unit that does all the work in the digital domain?

I am wondering if the one less digital to analog conversion is better given that I am still going to be using analog amplifiers and speakers.  If the G68 needs to send a digital signal all the way to Meridian speakers, I am not going to improve any sonics.

the Meridian G68 digital outputs are proprietary and are meant to be conected to Meridian active loudspeakers.  In addition to the digital signal, they require a secondary communications link that probably does things such as control volume.

The Mini-DSP module is more of a low cost band-aid if you want to enhance a current system.  I think you're better off just replacing the Marantz 7701 with another processor that does all the EQ / Crossover / Room Correction that the Mini-DSP does.  Emotiva XMC-1 (possibly with Dirac room control)? 

Outlaw 976 has 10-band parametric EQ for each channel.

There are lot's of others, but depend on your budget and if you want automatic room correction of some sort.

I don’t think we are on the same page. The Marantz 7701 has room correction software.  The MiniDSP is being used so I can tri-amplify my main speakers.  I use filters and crossovers in the MiniDSP to accomplish this task.   I am unaware of any pre/pros that have the ability to function in this capacity. I also am unsure why there would need to be volume control outside of the Meridian G68. It contains a volume control that should adjust the digital out gains even if used in an all Meridian system. Why is the volume control on the device if it is intended to be used in a system with that control further downstream? Again, I am wondering if anyone has used a MiniDSP downstream from a digital out on a Meridian product? And what kind of success or failure they think it was?
