After doing some research on DACS and some more critical listening today and some needed fine tuning on speaker positions (they were inadvertently moved a tad recently), I've decided what I have sounds fine + will most likely stay put.
Most issues I hear appear to be unique to specific recordings.
If I were to invest more in my system at this point, I think it would be in a more powerful amp to flush out the low end even further with the Ohm 5's. Those babys love the juice man! They suck up the power and convert it into increased presence and dynamics without going the slightest bit harsh.
My only urge is to perhaps be able to add even more impact to the recordings that have good dynamic range, like the large scale symphonic works, to see how far things can go.
If I bumped up my amp, I'd probably stick with a larger Musical Fidelity in that things are sounding, dare I say, near perfect.
