Primaluna DiaLogue HP Integrated Vs Line Magnetic 845ai

Congrats...Certainly different, but WARMER than EL 34? I’m also looking to pair my Harbeth (C7’s) up with an amp. I went on HUG (Harbeth users Group), and Alan narrowed it down to NAD or Dagastino, or simply choose the one with more power. Yes, that was a poke. (-: It’s just very strange to me. I’m thinking 65-70 tube watts...or if solid state, I will likely go 100 watts. My price range is slightly lower than yours. It seems like the 300B (likely not a good choice w/Harbeth) or 845/211 are regarded as elite output tubes. I only have experience with KT 88, EL 34, and most recently 300B. The latter, I use to drive the very efficient High impedance Altec’s. Perhaps I have cornered myself in to going Solid State by purchasing the C7’s. Maybe not a bad thing, but I would like to have the option to go either way. Interesting to me is Quicksilver for tubes, and Belles for SS.

I owned the PrimaLuna HP with EL34's and to my ear the LM 845ia is warmer and has more tube bloom...the music feeling more palpable.

And yes, the Harbeths aren't rated as all that efficient. Still they seem to drive my LM without any problem.

I have the Primaluna Dialogue HP Integrated with KT 150's and NOS tubes. The Line Magnetic 805 I bought was so much better than the Primaluna that there was no point in A/B ing them. I just immediately boxed up the Primaluna for sale. 

The Lane Magnetic is quite a step up from my suped-up Primaluna. It's much sweeter and less grainy, cold and analytical. The PL sounded dry next to the Line Magnetic with stock tubes. More extended in each direction but never harsh.
