For many enthusiasts like me, there is always going to be a stronger pull towards separates - they're just too cool. You got your phono & preamp in the rack under the turntable, and a monoblock next to each speaker. Just as God intended 😎
Most integrated amps truncate the preamp gain stages, which is OK for digital sources pushing out 2 - 4V+ signals. But as an analog source first guy (often no digital), I appreciate having the extra gain on tap to fill in for that lo-MC or tape deck when needed. And of course, more tubes from separates means more rolling opportunities.
