Sounds like you have impedance mismatch with primaluna evo 300 and DI, the Eve 300 has 16 Ohm taps, they are probably not wired optimal for DI’s 2~4 Ohm load.
I tested the Klipsch Heresy IV at a Seattle dealer, they were driven by Jadis Orchestra Black EL34, it was not my cup of tea, the Heresy was too exciting sounding, they made my head hurt after awhile.
I am thinking to get a pair of Tekton the perfect set 15, just to test it myself, I know there are a lots of Tekton haters here at the gon but hey, people have the right to be different. My current speakers are Tannoy Turnberry and Zu Druid MK5.
