I was told there would be no math...

I've never considered 500-series due to price. Please forgive my ignorance, but are we looking at >$600 for a DiY 500-series rack solution?
And what DiY 500 series modules are available besides the CAPI pres? Most non-DiY stuff is too rich for my blood, so I don't see myself loading up on manufacturers modules.

you can make something nice that will impress for "general use" yielding high quality results with +/ 15v. That's why the 51x alliance 500 series rack is so exciting, it has 24v rails to sit along side the 15v rails, it opens up a lot more possibilities to designers, and can keep build costs down. 8) |

I went 500 for space savings. My rack is all CAPI right now, running at +/-16. +/-24v is only about 2-3db more signal, it's not really the savior of audio it's made out to be.. Anyway, I love my rack. I'm thinking of another one.

I'm building.tube pres at 24v, I'm also building some nv73 pres at 24v and saving 55$ On each, I also run 2 boxes off of one PSU, do that with a standard 500 rack, you can't, it's badass, and expands the possibilities of 500 series design

500 modules have power rail limits, power current limits, a shared supply and ground increasing crosstalk.
The format is also very crowded for larger hands.
Too bad the dbx/Aphex racks were not popularized as they had more room, a beefer power supply, + - 15 and + - 24 volt rails, better construction, etc.
When you have an analog console with -90 dbu stereo crosstalk at 10k hz, 500 modules in stereo will collapse that crosstalk spec.
One thing you will never see is a decent Audio Precision stereo crosstalk test done on a pair of 500 modules or a 500 series rack, the results would not look pretty.
Back in the 1980's when powered gear racks came out, they were marketed as a way to lower the costs of multiple processors and to save weight and space.
