Poll: Which rack s would you use and why?

I have reduced the number of components in my system and sold two 5-shelf racks and a turntable stand. In the interim, before I get my new DAC, transport, line stage and turntable, I have my amps and one box CDP on the floor and the soundstage obviously got better without all the clutter. OK, here is the poll question:

I have a 14' x 17.5 ' room. My speakers are 68" out from the wall (to the front of the speaker). My amps will remain on the floor on SRA dedicated bases. That leaves me six components (including the turntable) to put on shelves (racks). Which would you use to minimize the adverse effects on the soundstage -- two lower (e.g., 31" high) three shelf racks side by side or a single higher (say 45") six shelf rack and why? I am hoping to hear from people who have tried both in their rooms as well as sound engineering type responses.

I am trying to decide what I am going to do so this is not a hypothetical question. Thanks in advance for your ideas!!!

PS - you can also recommend anything else (e.g., brands of racks. other positions options to the extent possble, etc.)

Thanks.
