While I own and highly recommend getting a Shindo preamp (Monbrisson) for the reasons mentioned above, I would be very cautious about Shindo amps with speakers of that sensitivity. I tried their 40 watt monoblocs with my 90 db speakers and figured they might work, as my 60 watt Jadis amps had been fine. Unfortunately, the Shindos just didn't work--dull, lifeless sound, very restricted frequency range. I had heard the same amps sound absolutely beautiful at the dealer's showroom, with more sensitive speakers, so I knew what they were capable of with the right speakers. If you want to buy Shindo amps, you really need to try the amps you're interested in with your speakers before you buy, as I did.
Also, Shindo preamps as a general rule don't really seem to work well driving long interconnects, so if you have anything longer than a few meters between the preamp and amp I would again suggest an audition before buying. I didn't get my Shindo preamp until I moved to a smaller room and had shortened the length of interconnects to the amp to 1-1/2 meters.
