Sources: Denon X5200 or Pioneer SC-87 (haven´t decided yet) and Marantz 7055 amp, Oppo 103, Xbox One, Wii. Used equally for both movies and music.
Will the 3005 satellites pair well with the LS50s? Is the MLP appropiate for the LS50s or will they be forced too much?
Also, if I can´t get the third LS50, would I be better with no center and leaving the Right and Left handle it instead of an inferior speaker?
Finally, I don´t have space for stands so these would be sitting on top of Furniture, but at ear level. Would this diminish their quality?
The LS50 speakers are rated at a maximum continuous power of 100W, with 85 dB/W/m sensitivity. They're meant to be for near field listening and your distance of 10' away from the LS50 is will be an issue to reach 105dB peak. If you can reduce the distance to 9.25' and have them placed close to the room boundaries, it'll reach that peak of 105dB. Consider crossing over from the LS50 to the subs at say 100Hz to gain some additional headroom.
Email KEF if the 3005 egg satellites will match with the LS50. I got a positive response back from KEF in matching the E301 with the LS50.
The Denon X5200 has sufficient power to drive the LS50 in peak power demand in stereo mode and also in multi-channel surround.
Have a look at other Internet Direct (ID) sub companies rather than KEF. You'll get a lot more sound quality for the money. The ID sub companies make better subs than KEF. A few to consider include:
Seaton Sound - the SubMersive ($$$)
JTR - Captivator ($$$)
If you can't get a 3rd LS50 for the center speaker, consider the R-series from KEF, which has center speaker that can be purchased separately. The R-series have a higher sensitivity speakers (R300) available and if you can't reduce your listening distance, this might be the better option.
