Spendor SP 100 R2 or Harbeth 40.2

the above review will help you

i have the 40.2/40.3xd as well as the sp100 r2, to me they are both truly excellent wonderfully coherent big monitors with similar personalities (easeful effortless natural presentation of the music with inner detail well integrated into the overall soundstage, excellent bass response, magical with voices and acoustic instruments)

harbeth is less efficient, a bit warmer/smoother, likes fine solid state amplification for best bass, sp100 r2 has a touch more forward treble and upper midrange bite, touch more air/snap, 2-3 db more efficient higher impedance, thus more suitable with tube amps than the harbeth

with proper system/component matching and placement i really don't think one outperforms the other

note differing tweeter placement on these two models, so stand height needs to be a bit different for the two

BTW- Most of my gear is Pass Labs- 250.8 amp,,XP 22 preamp....XP-17 Phono

looks like you are good here without any need to budget for upstream electronics upgrades as you start your journey

Have fun, sir!

a couple more reviews FWIW

.In the sum, the Monitor 40.3XD possesses that difficult to define but instantly apparent impression of authority on any and all kinds of music. From the simplest to the most demanding, from a whisper to far louder than you can stand, you have the sense there is no kind of music that it cannot take in easy stride and reproduce as truthfully, beautifully, and faithfully to the source as the current state of the art will allow." - Paul Sedour, The Absolute Sound February 2017

I can confirm that this character continues on into Classic 100 model [=SP100 Mk 3].  BTW in the same room and system, the Classic 100s sounded significantly better than a pair of D7's.
