I heard a leak 230 with the ls35a at Axpona and it was fantastic. I think it’s SS.
I have the Q7 which is a slightly bigger cabinet and I use the Rogue Cm2. Really like the combination but using kt120s. Will try the el 34.
I had primaluna prologue 2 and loved it. The dialog series has too many tubes and is costly to replace but I hear great things about them and Raven audio.
all the best with your search. I’m interested in what you learn. My taste in music is very similar to yours.
