Musical Fidelity M5Si vs Rotel 1592 Integrated

I'm torn between these 2 amps for a smaller room roughly 12x12 and have narrowed my search between these two integrateds for my KEF LS50s.  I heard the Musical Fidelity at a dealer recently and loved the sound it reproduced.  Very clean and smooth maybe a little warmer than I'm used to. I have owned Rotel in the past and thought they were great but maybe a tad bright. Has anyone had experience with either one?  The Rotel is at the top of my budget and I don't really need all the features but the built in DAC in both is what I like since I mostly use digital as my source.  I know they are both great products but any help would be greatly appreciated.  I am actually in a trial with the MF and have it at home to audition.  My dealer did not have a Rotel to demo (had the 1570 but not the 1592). Thought the 1570 was very nice but a little fatiguing after about 30 mins of use.  If anyone has any input on how the 1592 sounds in comparison to the 1570 as well that'd be awesome.  Thanks!
