I'm late to the conversation. Not defining target curves was pro and not a con when I made my purchasing decision (I bought the Lyngdorf MP-50 in 2017). Voicings were a major selling point for me.
Let me first say that my room is more of a game-room than a home cinema (I just added a shuffleboard table). If I had a purpose-built room like
I would have splurged on a Trinnov. In no way am I suggesting Lyngdorf is better, just different. I would place it above the Marantz/Yamaha/NAD flagship preamps (I also have a NAD) and below the Storms/Trinnovs. Maybe closer to Datasat & Theta than some might think.
I don't know how the target curve calibrations and measurements work on the Trinnov. Do you re-run the measurements anytime you want to test a new curve? How fast can you switch between prior curves?
What RoomPerfect allows me to do is make room position measurements without worrying about extraneous noise. My 5-year-old playing nearby [or me tripping and falling] simply lengthens the position measurement, no need to restart the process. Also, you don't have to complete RoomPerfect calibration in one sitting.
While I can't weigh seating positions like on the Trinnov, I can define multiple focus positions. A focus position is basically defining a MLP/sweet spot. As more focus positions and room measurements are added room knowledge increases. You don't have to get room knowledge to 100% the first day, or ever. You can enjoy a movie with the family and add more room measurements later.
Instead of a target curve RoomPerfect attempts to preserve the power response of the main speakers. It also prioritizes taming room modes in the time-domain rather than created a flat amplitude response (ala Audyssey). The user can customize the amplitude response targets separately from the RoomPerfect calibration process.
The beauty of it all is being able to switch focus positions (there is also a global option to provide a more consistent seat-to-seat experience) and voicings in ~2 secs. It's just like choosing a processing mode like Neural X or Auromatic. There are even more options when defining sources.
Lyngdorf's documentation sucks to be blunt. Anyone interested is better off reading McIntosh's docs. Lyngdorf seem to rely on an experienced group of dealer/installers who also work with the Steinway Lyngdorf systems (a fully closed system along the lines of JBL Synthesis). We domestic Lyngdorf owners have had to rely on the European dealers, McIntosh owners, and reverse-engineering to understand the inner-workings (still a work-in-progress).
I believe 2019 will offer opportunities for direct comparisons between some of these processors. Definitely Trinnov vs Lyngdorf.
