How many dedicated lines are enough?

Until a day ago I thought two dedicated lines with 30 amp breakers, 10 guage solid core Romex was all I needed, plus a couple of Shunyata power conditioners and power cords and a few HiFI supreme fuses.

I isolate my Depth sub and Audio Aero cd player on a separate dedicated line with both plugged into a Hydra two.

The turntable, Pre/phono nand tiny 2 watt power amp were plugged into a Hydra 8 on the other line,same phase of the panel of course.

Just for something to try ,I set up a third dedicated line ,this time with a 20 amp breaker, same Romex for my 2 watt power amp.
The amp has a HiFi Supreme fuse and old vintage RCA rectifier, but other than that it's stock.The amp uses a Shunyata Annaconda Helix power cord and it's plugged into a Shunyata Venom recptacle at the end of the dedicated line.

The results were more than positive, perhaps just getting the amp out of the power conditioner, hydra 8 was the answer.I used to think the amp sounded better in the Hydra 2,but since we're only dealing with 2 watts I didn't think that there would be much difference, so my plan was to filter and isolate the CD player the way that I did and plug the amp into the Hydra 8, keeping it all analog.

I am curious if others have had similar results using numerous dedicated lines and further isolating the components?

So far for me,the cd player needs to be on it's own line,then the amp, and then a third line for everythingelse seems to be the best solution.

I did try everything plugged into the Hydra 8 on one dedicated line and didn't like it .
