Jeff Rules! These were returned for refund. 
I had 4x JISBOS kits (1-channel/board). You can use this as a buffer for 2 separate stereo amps, with the SOHA amp or standalone. I was planning to use this as an inexpensive balanced buffer but have moved to other options.
Price is lower than what I paid from GlassJarAudio, $35/pair.
Thanks
