I chose RCA input for the SEQSS because going with XLR in excludes 90% of the market for the hardware. I chose balanced out simply because the amplifiers used are assumed to be balanced in.
Balanced through is useful in eliminating noise. This requires properly internally grounded hardware on both ends of the cable, which, over 45 years as a live and recording musician, I have had many first hand experiences demonstrating that that is not the case.
With RCA in, if the result is that there is unacceptable noise, an RCA transformer adapter for RCA jack-equipped preamps or an XLR>RCA transforming adapter for balanced out jack-equipped preamps is the correct option.
Technically, this is the 2nd best way to achieve noise-free operation, but in the app we're involved with, there is typically no problem with noise and thus no advantage either way.
The nonsense floating around that XLR somehow magically audibly enhances the actual signal is just that.
