Which Sub. Rel B-1 or Fathom F-113

Ozzy...I run my X-2 series ll's full range and use my two Gotham's to fill in the bottom. Depending on the input impedance of your amps you might need a tube buffer or something similar as you will be running two loads in parallel. Here is how I solved the problem in my system

Thanks, My Pass Labs Preamp (XP-10) has 2 sets of outputs.
So, will that still be a problem?

My Ref 3 also has 2 sets (4 in all)....two balanced and two SE, so it will be no problem

So why did you have to use the Tube Buffer? I read your link but I still dont see why it is needed.

With two unequal loads running in parallel it would have put great strain on my Ref 3. This way it is prettty effortless. It was done also at the advice of the people from ARC
