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

Wojciech Pacula, a well known Polish reviewer (6moons, etc), has a pair of 40.1 with Soulution 710 in his reference system.
Maybe it's no coincidence. Perhaps a pair of Job mono amps would be the poor man's equivalent. Harbeth dealers generally seem to pair them with British integrated amps, and I know that Vinny Rossi shows with Harbeth, but those both sound very different from fast solid-state.
Try Chord or Exposure separates; both would count as "fast." 

Naim would be worth a try also; but you'd probably need a 282/HicapDR/250 combo. 

I've heard all three run big Harbeths (and Spendors) very well. 
I don't have the big Harbeths but for my office system P3ESRs I am using a Rega Brio-R, Apollo-R, and a DAC-R.  Works well together.
