good is always the enemy of the best, as I understand it.
despite what or where one feels the need to experiment with what they deem already quite good, or very nice, it just seems purdent to develop a methodology for direction, a base line from which to eveolve, and a destination that can be reached within the confines of the gear on hand.

FYI... perhaps some plants on that window sill could aid in defraction. ficus and spider plants go a long ways to diffusing sound or ameliorating reflections.
Elizabeth's path included a speaker upgrade and some efforts comparing outlets and powewr cords. among other things.
Inna says begin with the cartridge. fine. start there.
it seems prudent to say 'attack that which is blatantly wrong first.
thereafter, a consideration is that once any part of the whole is altered, it becomes the fulcrum all else is hinged to. once an accepatable level of higher performance is extracted, it must be revisited. IMHO.
EXP has shown me trying out PCs on the source, and powewr train, with power amp (s) being flung into the fire first is my baseline I'll let all else balance on.
I would not think to begin shuffeling wires, footers, platforms, etc., unless I felt the outfit was under achieving.
IOW, a 5K to 10K retail priced rig is only gonna yield so much regardless the tweaks, though these tweaks may very well satisfy its owner.
with a rig running 30K to 40K MSRP it might need some experimentation to bring out its best, and that might mean replacing one or more of the electronics for better synergy, and not merely fiddling with wires and the aforementioned bits.
the crucible is always gonna be the ear and mind set of the beholder as to thier perception of what needs to be chased, and for how long.
how many here are component junkies? wire mavens? acoustical treatment obsessive? Power conditioner experts? or rife for taming bass?
the gear itself is IMHO the main limiting factor.
in short, there is no etched in stone tablets plan for attacking and extracting the best from one's system in reality.
just get in where you fit in, or not at all if for you, good is good enough. there is no law against it.
