Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems Tri-Stereo, will I end up with Meridian Trifield now?

It's not a question of appreciation or sympathy in what you're trying to achieve, it's that I simply don't believe your setup will achieve what you said you wanted, which is Meridian Trifield. Trifield is a very specific way of processing two-channel audio in order to extract information for a centre channel (and surrounds, if present). It does this by extracting phase and amplitude information which it then distributes on a frequency-dependent basis, according to proprietary algorithms.

Not only are neither your NAD, nor Dirac designed with this in mind, they are not even three-channel capable. What you are attempting is analogous to strapping a jet engine on the back of a Ferrari and then asking if it will corner as Maranello intended. You will get something, you might even find it enjoyable, but it will be unpredictable at very best, and certainly nothing to do with what the designer intended. If I understand correctly, you haven't even listened to Trifield as it was intended yet, so how would you judge whatever results you are getting - you have no reference.

Honestly, I would say either stick with what you have with your very nice NAD/Dirac setup -which I'm sure is excellent- OR try your 568 as it was intended, to see if you like it and in which case explore it further, or look at higher-end Meridian options, such as 861, which have Meridian's own room correction built in, which was designed to integrate correctly with all the processing modes the unit offers.
