Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems Interesting Discussion 861v6 v ADA

There is much to gain from running multiple subs, each on their own PEQ, off a single Meridian sub output. Multiple subs, well implemented, sound terrific. That being said, it's not easy to implement them well. (In my case I run two subs off the single M sub output, and use a QSC to get them properly time aligned and frequency/phase aligned.) With the proper measurement equipment speaker distances are then set to compensate for the QSC's latency.

There is also much to gain from adding PEQ after the Meridian, if properly implemented. I understand the theory of the incremental A/D and then D/A stages being harmful, but that has to be put in the context of the gains that can be made. In my case I use a heavily modified balanced Audyssey Pro (it does not handle the subs) rather than MRC, and it makes a noticeable improvement. I have heard another system that puts a heavily modified Tact in between an Audio Research preamp and top of the line VTL amps, and it too generated a material improvement.

I don't believe I am running either a "QSC system" or an "Audyssey" system. I can easily hear the differences between processors, with the gains from the 861v4 to v6 being staggering (IMO).

That some might prefer an ADA or an 861 should not surprise anyone. But that's not necessarily because of the processing used downstream of the device. The virtues of "chain purity" are greatly overestimated, again IMO.
