Given your room size, the Pointsource 10 will deliver more pressurization than that model Harbeth, whatever its other virtues. It comes down to your priorities. Based on my listening experience, the Pointsource 10 is balanced to be neutral, and from all I hear about Harbeth, they are balanced to be “warm”. But the 7ES is a smaller box and an 8” woofer, 86 dB vs 91 dB. That is a big difference. Your stated music preferences tilt towards greater cone area and sensitivity being advantages.
MoFi or Harbeth (used)
I’d be grateful for advice choosing between the MoFi SourcePoint 10 or a used pair of the Harbeth Compact 7-ES 35th Anniversary Edition. My room is about 10 by 18 and I will be slightly off axis. My associated equipment is Krell KAV 250 a amp and Audio Research pre amp. I use a BlueSound Node as the source. I listen mainly to blues, jazz, and rock. Thanks very much for any advice.
