Haven't checked what I did. Not sure it matters to me. I'm always trying to find the synergy with my system. Think for most of us, our virtual systems are just a moment in time. They are constantly changing and evolving.
My speakers get swapped out every once in a while, still working out what footers work best for my TT, changing cables from time to time.
My camp would be speakers make the biggest difference. Most other things are tweaks. However, I did do a complete referb on my pre and power amps. Replaced like 100+ components. That did make a HUGE difference in sound from bottom to top. That totally surprised me.
