I have only experienced a switcher in a store.
My general concern with "A" vs "B" comparisons is when listening to music our brains can 'color' the sound by adding memories to the equation. Therefore, I've been more inclined to be introspective on what I hear and how I feel during the listening.
And in the end I believe most of us like listening to music so I am comfortable with my decision being my decision because I'm sure that with enough time and effort I could realize my decision was merely good versus the 'best'.
In other words, enjoy your process!
