Hello, I just saw this topic three years after it was published …
i play both amplifiers with Harbeth speakers and I find them both extraordinary.
the Primaluna with the 6L6GC valves is extremely musical and gentle, very refined and coherent. True and real. I use Belden 9497 speaker cables. They just match perfect, offer a wide and deep soundstage, rich tonality and precise and homogenous sound.
