@OP,
I own the Primaluna Dialogue HP integrated. It's great. I do, however, think, you might want to try a SET amp. You do not need much power to make those C-Walls sing. I should know. Why? Because I have Klipsch Forte IIIs (in addition to less efficient speakers) and they sound better with a SET amp than the Primaluna, in my room.
You could start with a Dennis Had amp (find him on eBay--he's the former owner of Cary Audio). Wolfe (above) has one. https://www.ebay.com/itm/STEREO-TUBE-AMPLIFIER-INSPIRE-by-DENNIS-HAD-300B-TRIODE-SINGLE-ENDED-AMPLIFIER/153463991221?hash=item23bb2aabb5:g:j7sAAOSw~PVcwdjC
I built the Elekit 8600 300B amp recently reviewed in Stereophile. In a few nights you can have SET nirvana for ~$2K--if you do all the upgrades. https://www.stereophile.com/content/gramophone-dreams-27-elekit-tu-8600r-amplifier-kit
