I recently purchased the Mission M33i from my local audio dealer. Out of the box the Mission M33i seem to sound if anything a bit dull, but give them about 8 hrs and they really come alive. The sonic abilities of the Mission M33i is outstanding at this price. They seem to work well with my Marantz PM4200 because the PM4200 is only 30 watt/chanel the 8 ohm means they are easy for the amp to run and the sensitivity being 90db give you extra volume from a lower power amp. I think this is definitely something to consider when buying your speakers the higher the load impedance (in ohms) and the higher the sensitivity the easier they will be for smaller amps to drive. This is something to bear in mind a 30 watt amp driving a set of speakers rated at 87db is fine but if you use the 90db sensitivity speakers it would mean your amp would be a 60watt amp so the is great advantage in checking the sensitivity befor choosing your speakers if you have a lower powered amp I would recommend you experiment with the position of the M33i to achive the best sound in conclusion the M33i represent excellent value for money.
