When Did Your System Disappear?


As we upgrade our audio systems, things (hopefully) keep sounding better and better. I have found that after a certain point, the system completely disappears. It’s no longer a pair of speakers, amps, preamps, sources, etc. Music is created out of thin air floating between and behind the speakers with little to no colorations in the sound. The regular audio verbiage can be thrown out the window because all you hear is the recording. If something is bright or harsh or bass heavy, it’s the recording not your system.
I noticed this when I modified my source and preamp to accept better power supplies. Using a combination of linear power supplies and large SLA batteries took my system to a new level where the equipment just disappears. Of course, this wasn’t the only thing that helped. Up to that point, every component has been experimented on to achieve a high degree of synergy. Interconnects, power cables, speaker cables, etc. all play a role too. Everything matters. 

My question to you all is when did this happen in your system? Did it develop slowly over time or was there a definite change that occurred with a certain upgrade?

“Active listening”  is the whole point of the speakers disappearing no matter how good (or bad) your rig is. What you bring to a listening session is the determining factor.
When I was 15 my system unfortunately disappeared when someone broke into our house and stole the whole rig. This later turned out to be a blessing when my dad gave me some money from homeowners insurance and purchased a better system and my first Thoren's TT a TD-160c. My current system disappeared when I made custom cabinets for my speaker's with better interior  insulation, upgraded the XO cap's. 
My system in college LITERALLY disappeared..... it got STOLEN!  It was a blessing in disguise though..... it was all JVC Japanese mid-fi (1984), and this event forced me to seek out a high end audio store that introduced me to NAD and Boston Acoustics.... great intro gear for a college student.  I still have that NAD 3150 integrated!    

...when I boxed up all the components and loaded them up in a "climate controlled" storage unit, in preparation for listing our house for sale...

But seriously, after I got the room acoustics under control, the synergy of all the components really started to shine.
