Like with most things, there’s no correct answer here - it’s question of swings and roundabouts.
I started mixed and moved towards one brand over the decades. However, there accessories and tweeks that the manufacturer may not necessarily sanction.
Maybe, I am losing out on the very best components here and there. Plus, I haven’t fine tuned the character of the sound exactly to my taste. Yet I get the massive benefit of synergy.
For the past few years, I’ve had in mind to introduce a little more variety in the loudspeaker department to try to get the best of both worlds.
