Electronics for Harbeth, Especially Monitor 40 series


Hello,
Has anyone tried matching "fast" solid-state to the big Harbeths. Something like Goldmund, Soulution, Spectral, etc. The speakers have great tone but can be a little stodgy. I was wondering if this would open them up a bit. Also, has anyone tried using an LDR passive such as Tortuga or Lightspeed for the same reason

They have been refined and defined, sold a ton, several tons since 77’ perhaps. It may be a safe assumption by now to say R&D has all but paid off on more than a couple of their more current designs. So when is cost going to come down on Harbeth speakers? :p
I never thought about at atma-sphere but it makes sense now that Ralph brings it up. They are fast and clean. If the speakers are impedance friendly and that's the sound you want, they are fine amplifiers in my experience.
I have been using Spectral pre and amp with the M40.1 and have been very happy for the last 7 years. The M40.1 are somewhat amp friendly but have a lower sensitivity 84-86 db/1 watt/1 m. I do sit close to near field ~5-6 feet. I listen at about 75 db with peaks in the mid to high 80's max. 
I have 40.1's and I've tried many amps and integrateds.    Tube amps are superior in my experience.  Rankings as follows:

  1. VAC PHI 200 (current amp)
  2. VAC 70/70 Signature (130 pound beast, great on vocals and jazz)
  3. McIntosh MC275 MKV (fun, gutsy classic amp)
  4. VAC 30/30 (incredible amp with midrange to die for, but could use a tad more power)
  5. Plinius SA-102 in class A (best solid state I've owned)
  6. Bryston 4BST (decent value at used prices)
  7. McIntosh MA2275 (too soft and mellow)
  8. Musical Fidelity M3 Nu-Vista (awful gear... will never buy MF again)
