The passive ambient room noise Is important and not always super expensive to attack, especially if you have a DIY mindset. Think treatments, curtains, seal windows and doors, use weather stripping, double Sheetrock, green glue, etc...
the active noise is a bit more difficult but still can be attacked , wall warts ( the switch mode supply type ) on a separate conditioner AND a separate dedicated circuit, etc
get your power panel aligned, motors and hash producers on opposite leg of the analog audio
optical isolation
physical isolation, TT and balanced phono pre in separate room or failing that significant isolation
electrical components isolated with drains....
have fun
never lose sight of the emotional connection to music
