M33 for £110? Damn I got mine a few weeks ago for £130! Not sure about the M73's but I am very happy with my M33's, after a good run-in they are sounding great with films and music
There is very little difference between the M33i & M73i to my ears - personally prefer the look of the M33i as it doesnt have the large plasticy front baffle and so looks good with the grills off - there is no way I could live with my M74i speakers without the grills on because of it.
Sarll - I am very impressed with it (I use it purely for movies/tv - no music (multichannel or stereo)
In my opinion when I was testing the Denon AVR range the 2805 pushed the limits of my speakers but certainly didnt go over them - the speakers didnt do justice to the 3805 and as I have no intention to upgrade the speakers any further the 2805 was an excellent partner.
I have a totally seperate stereo system which I dont think I will ever finish upgrading
