Epos M15 a good match with Primaluna prologue 1?

Hi, this is my first post here.

I heard Epos years ago when I couldn't afford them, butI absolutely loved them at the time (both the ES11 and ES14). Since then I've had Jolida with NHT super zeroes, and later KEF RDM1s. I can't remember the efficiency of those speakers, but I recall them being a little harder to drive with my 50 watt Jolida integrated.

Fast forward a few years and a few kids later and I had to abandon the dedicated music system for a HT system with a Harmon Kardon reciever and the PSB Image line (5Ts, 9C and surrounds). While I'm not that keen on the reciever, I absolutely love the PSBs.

Now I'm back to assembling a music system and picked up an integrated tube amp ... the Primaluna prologue 1. I'm also interested in reliving my past love affair with the Epos but can't find a local dealer. I'm looking at some used Epos M15s and was wondering if that would be a good match with the Primaluna or if it would require more power. I'm also wondering how the M15 stacks up against the PSB Image 5T. Has anyone been able to compare these two lines?

Thanks!
