Balanced to RCA

Im just trying to go from:

 CD player to dbx
(balanced to balanced?) 

then

dbx to amplifier (balanced to unbalanced?)

• (Pin 2 is connected to the center RCA pin and Pins 1-3 are grounded to the RCA chassis body)

• (Pin2 is connected to the center RCA pin, Pin1 is grounded to the RCA chassis, while Pin3 is connected with a 10 ohm resistor to the RCA chassis)
  
  

• (Pin 2 is connected to the center RCA pin and Pins 1-3 are grounded to the RCA chassis body)

I am going through the same labyrinth
I have a before-amplifier ( not to be confused with the preamplifier) (It is a dox drive rack) which I’ll be using as an external crossover. It has female XLR inputs and male XLR outputs. My question is what is the best way to convert
RCA to XLR (cd player to dox)
and
XLR to RCA. (dox to amplifier)
  

-typically on the second half Im wondering which would be preferred ?
1. xlr cable from the dox to either: 
     A. Cardas Audio Male RCA to Female XLR Adapters plugged onto my amplifier (McIntoish 2105)
     B. A transformer. (SO max}

What I like about A. Is there is only one set of cables versus B. Two sets of cables.

depending on my speaker choice Ill need need to be bi-amping or tri-amping… so cost is a consideration x2 or x3…

2.???
