It takes about 6 months for speakers to get broken in to sound their best. The room you place your system in is as important as the components you have picked for your system.
What matters most, is you like the sound of your system.
5 years ago I purchased an integrated Primaluna, built my own speakers and love the sound of my system. Could it be better? Of course, if I want to nit pick. Perfection is an opinion, not a reality in Audio reproduction. There is a fine line between, "how much better per $1000 will be worth the cost." For those with deep pockets, well go for it. For me, listening before I purchased maximized the dollars I spent. I had about 100hrs in my speakers before I said, this is what I want. Perfect? For my dollars spent, for me it's darn close.
