Frank Ultrabank vs Plixir BAC Elite 1500

Guys, I was just wondering if any Frank Ultrabank owners here have a Plixir Elite BAC as a complement in the system. In other words, is there anyone who has both Frank Ultrabank and Plixir BAC Elite in the system. I am curious to know how do both compare. Which components sound better on the Frank Ultrabank and which components sound better on the Plixir. 

Currently I have a Frank Ultrabank in the system but there are insufficient outlets (only 2). The damn thing at 45kg is too big and heavy. Otherwise, I would have bought another unit. I'm now considering the Plixir Elite BAC 1500 due to the lighter weight (although it's more expensive!). 

Any advice would be appreciated.

Get 1 more and the results will be far better. I have 2 Frank power banks. Another friend has 5  in his system
