A/B testing of RCA interconnects using Y splitter- Thoughts?


I am trying out a few sets of cables and this thought occurred to me but would like to get some more knowledgeable folk's opinion ESPECIALLY on the safety side of the amp & phone stage.

Option 1- connect splitters to the output of PS and connect the two cables to compare. One set to input 1 of integrated amp and the other set to input 4 of integrated amp. I would then switch between the two inputs. This I believe would be a level playing field where the output db and the quality of splitter would be the same for both cables.
Can this harm the amp or the PS?
PS=Sutherland Phd
IA= Luxman L-507ux

Option 2- Just use one cable (A) for some time, learn the music well for a # of hours or a week (just to through a number out there) AND then switch to cable (B)

My intuition tells me option 2 is the way to go but I only will have the cables for a very short time so that is why I started off thinking of the viability on option 1.

Your thoughts would be greatly appreciated.
