I had some big plans with this thread's initial question.
I ended up with 2 2-channel systems and 2 headphone systems and did not need the dual XLR outputs from a single preamp. I decided to use headphones in the same room as my big speakers. So no need to have 2 speakers sets in this room and 2 XLR outputs from a single preamp.
I used the Benchmark HPA4 preamp for the big 2 channel system.
The second 2 channel system in another floor is setup with a Krell K-300i integrated.
The CODA CSiB integrated is used on headphone system 1.
The Topping A90 headphone amp for headphone system 2 (along with the Benchmark HPA4).
This is a lot cheaper than I initially planned and sounds great.
