If you were serious about sound you would...

You would not use a Mac computer Waay to much noise with programs in the back ground , your active speakers No thanks far better quality sound from a dedicated amplifier , you want a great reference dac , and SS drive, and dedicated 

 Server . Plus the cables they use in studios are subpar vs good audio.

having owned a Audio store the quality they use in a studio especially cables ,

I tried using these name brand cables in Audio it just restricts the presentation .

for amplifiers,preamp Bricasti has been doing pro audio for 20 years and night and day better then any class D amp stuffed in a speaker Many Top studios use Bricasti also a vacuum tube mixing council like Manley much more natural and just like Tube amps used for guitarists they just sound more natural , All this  is necessary if you want an analog type recording , many new pressing they are bright and just thrown together ,thsts why many older recordings had more life, Care went into the mixing , that’s just my observation ,and opinion .

That list that you mentioned is not high on in any category ,andi have owned a audio store went to many audio shows  and built many audio systems. System 

synergies by far the best important , and many pieces of equipment I have seen in mastering studios is just not that good , for example many use Mugabi Audiocables 

or others it’s not that musical. Now Bricasti is a solidAudio brand that started in mastering studios and is well respected . There are many Loudspeakers -Audiophile that use better quality  Loudspeakers for much less monies. 
Musicality is what counts most ,,the mastering is sometimes. The biggest limitation 

who mixes the recordings . Vacuum tube has always given the most natural

presentation, playing guitar pretty much the vast majority of amplifiers are Vacuum tube , even Vacuum tube mikes Many use .  That’s why many older recordings sounded more natural , the majority of Beatles ,masterpiece Pink Floyd Dark side of the moon , solid state can be verygood , look at Manley again Vacuum tube mixing boards,
