I don't know how shunyata fares compared to monster in dedicated lines ... I don't have any, one of the downsides of renting an apartment... but I did use monster's HTS 5100 prior and was warned to avoid piggybacking the 7000 AC filter on top of it by a retailer due to current limiting issues. The monster gear worked really well for video, but that's where its benefits ended in my system ... introducing the hydra was like opening up the music and lifting the veil off ... the difference was obvious ... I now use shunyata in both systems and would recommend it for sure ... see if you can audition one (with a 20 amp IEC powercord for it), that way you'll know for sure if it works for you. If not PS Audio, Sound Applications, Richard Gray and Transparent Audio may be of interest to you ... I have come to think that powerconditioning is key to getting the best out of a system ... as is proper isolation.
The Aeon'i are part of my HT system ... which is more or less mid-fi ... certainly not as well setup as your system, but I still love the sound coming out of it ... it has that electrostatic appeal on a moderate budget (Logos, Clarity surrounds, Audio Refinement Pre-2 DSP and Multi-5 amp, Modwright Sony NS999ES universal player with external powersupply, all ic's from pre to amp are Revelation Audio Labs (RAL) paradise, ic's from player to pre are monster sigma retro gold, digital ic to pre is also RAL's prophecy (for movies only, music is played via pure analog path only), sc's are cardas cross to fronts and mit to rears, an older shunyata hydra 4 with a variety of powercords from audioquest/shunyata/RAL/cardas throughout) ... a small headphone system runs off it as well (Musical Fidelity X-can3 with Sennheiser 600's and the cardas headphone cable, ic's are cardas neutral reference) ... bass is augmented by a Tannoy TS 10 sub, but I prefer to run the Aeon i's full range for music, the Tannoy can't really keep up with them so it's limited to movies and I'm limited in the low end for music playback by the Aeon i's output here ... putting them on granite blocks helped a bit.
My other system is where the magic happens ... there I plan to listen to a few tracks from a CD and end up until my wife wants to go to bed ... which unfortunately is in the same room ... can't have it all! Together with my wife we chose cones for this system (Revelation Audio Mistral S6 with sub6, these are wonderfully emotional sounding speakers that blew us away at the Montreal show this year) and we have no regrets ... I used to think electrostatics were the only choice for music or movies, but I've come to realize that some cones have a certain way of communicating emotion like no other electrostatic out there ... weather it's due to coloration or not is irrelevant ... in this system they are amazing.
