Not to divert the topic, but I've read anecdotally (probably here) that Bob S. was not satisfied with 7ks, hence the early intro of 7200s. So I wonder also about the difference between 7ks and 7200s, and how the newer 7200s would compare with the 5200s. Has anyone heard the two 7s side by side and formed an opinion re the 5200s?
The D7K2's are a much better performing speaker than the D7k's (and also outperform the D5K2's)
There are defined reasons why the the D7k's had such a short life span (compared to typical Meridian DSP life spans)
Meridian weren't happy with its overall performance, which led reasonably quickly to it being replaced by its D7K2 successor. Bob Stuart's own comments about the D5K2 performance echo the above points
