Do I have enough power?

Challenges with manis:

1) right amplifier for best (not just good) performance with all kinds of music at target listening volumes

2) Need distance to walls for best results that justify the investment (not an unusual thing at all)

3) THey can sound a touch hot and less laid back compared to some lines, like PSB, for example in some setups, especially with some SS amps. Addressable via many common tweaks as needed though, nothing unusual there either.

I would love to own Mani IIs as a possible step up from my current smaller Dynaudio monitors if I could justify the expenditure. Maybe someday.

What kind of distance to the wall do the Mani's need to sound decent? That might be a problem in my room.

I like them at least 2ft into the room, 4ft is better, but they are better than decent - probably great 1 ft away. They're just not their best unless well away from the wall.
