Okay... Because I started to spin out of control and look at the Adam T5V and the S10 sub accompaniment to bypass the need for an amp...as well as like 5 other monitors.
Gosh there's a lot to learn, and decide.
Depending on what you want to achieve and what kind of listening you do, this may be a good solution.
I also went active since I got a pair of nearly unused T5Vs for cheap. I use a Raspberry PI as a streamer, which also provides the PEQ you want for the them to bring down the highs. To fill out the low end, I have a Rel TZero, which was fine with the passive setup I had before, but doesn't add much now, as the T5Vs reach quite deep in my room. I haven't really integrated it yet, but I may have to switch to a bigger sub (maybe the T10s is a perfect fit?).
Apart from that, I am very happy with the T5Vs, even without the sub! they play nicely in my untreated room.
I think with T7V or T8V, you don't necessarily need a sub.
