I should be listening to music
In addition to Jem’s advice above (and I’m a bit of a bore on this subject) let me suggest that the best rack might be no rack or a smaller rack.
It costs nothing to experiment with resting amps or sources on alternative pieces of furniture. I have had a monster NVA power amp on a sideboard with everything else in a rack (the phono and phono psu being kept as far apart as possible). This phono/amp combo is currently in storage and I’m listening to a Pioneer A-9 which was top of the range in its day with a matching tuner and a PL71. All are on top of the sideboard and I’ve no complaints about the music.
So try something different; it might save you a lot of money !
