Proac Studio 100 - will 35 wpc be enough?

Thanks for the answer. Yes, I agree, the Power is often overrated. Do you have the Proac Studio 100 as well?

Hi Chris, your amp will be plenty.  I ran a pair of the Proac D2 monitors, which had almost the exact same sensitivity as your Studio 100, off an Audio Research VSi55 integrated and I think those are rated for 48wpc.  The difference in actual decibels, between a 35wpc amp and 48wpc, is barely enough to move the needle on a decibel meter.   And the VSi55 was more than enough amp to play very loudly, loud enough to be uncomfortable.   Unless you're putting these in a huge room that is inappropriate for the size of the monitor, your amp will be fine.

Thanks Bcgator! That was what I needed to see! 

Chris,
I power my Proac D-30R's with a pair of Manley Snappers running in triode mode. They make about 30W or so. They easily power the D-30R without any struggle whatsoever. The Studio 100's have a similar impedance so I think you should be good to go.

I am a bit surprised that there are no posts by those who insist that they get better sound running their 104 db/w speakers with something like 200 watt amps instead of whimpy 100 watt amps.

Most of the amps I like are lower-powered so I agree with the consensus above.  I have heard the Tablettes, which are less efficient than the Pro Studio 100s, sound very good in a dealer's showroom that is about 20' by 25'.  The speakers are mostly demonstrated with 15 to 30 watt tube amps.
