This is great thread! My answer--I have no idea.
How great is Roxy's metaphorical assessment of the system?
Speakers = Body & Voice
Amplifier = Heart
Pre = Soul
I would add that Source = Blood
For years I fought the notion that the preamp was super important. Then I got a legitimate phono preamp (Manley Chinook--still own it despite lots of swapping around). That made me realize that if a phono preamp could make that big of a difference, how about the preamp itself? That was eye opening.
Maybe I should be asking myself, What component is the one to skimp on, if you had to?
