First: speakers quality improved by the necessary tweaks...
Second: room treatment...(absorption and reflection panels, Helmholtz resonators,Schumann generators...)
Third : amplifier and dac tweaked...
Fourth : Last but not least at all, tweaks and cleaning about mechanical vibrations, and the electro-magnetic grid of the room and the house...
My experience is contrary to many people : Buy good products but dont focus on pricey one at all; the most important fact for audio is not the price/ quality value of your gear but the way you install and implemented them in your room...The most astounding upgrade comes from that, not buying anything more costly...
