I am aware of how biamping works. In fact, I was hoping, in my system, to use a Class A amp for the mids/highs and a Bryston for the bottom end. Turned out the Class A amp was running the highs only. So I went for dual mono bridged.
Again, I understand what Paradigm is doing; JL Audio, among others, is using active room EQ to flatten out room resonances/peaks etc so if they have access to incorporate it (with ARC) I can see why it was done.
Don't get me wrong; I am not knocking the 9H, I would love them just as anyone else, but all I am saying is that they could of easily had a 9H and 9F version (for less money). Most don't care about the Class D amps in subs since the bandwidth is so narrow anyway, but on speakers I could see some raised eyebrows about it. The reason I find this significant is that, at the time, I had the option of choosing the S8 or S6 (analogy to the 9H or 7F for number of bass drivers) and I chose the S8 for the same reasons: it is not just the fact there is more bass but a bigger cabinet and more air to work with.
Regardless, I think it is a fabulous step up for Paradigm, although realistically I couldn't see myself with either; the S8's I have a still newer, with lots of life left in them, and with the addition of two JL Audio subs, provides a beautiful window on the music. Of course, on financial matters, there is always random chance once a week.....
