I don’t know if it will help but here is a very recent review of these loudspeakers, with brief comments on pairing them with appropriate amplification:
They don’t recommend anything specific, but it seems as though a very good and powerful integrated amplifier is what you need to look for (if you want to minimise the space used and get the best from the ‘speakers).
There are also suggestions on appropriate amplification in the readers’ comments.
If it’s not too late to send the 'speakers back you could perhaps exchange them for the wireless active version (more money, naturally).
