Is a high priced Line Conditioner needed

It seems you are ok with your sound. Why not just enjoy? Of course there will always be improvements; like a 2014 Ferrari should be better than a 2013. This music hobby could get to be like owning a high maintenance yacht-simply a place to spend money-

Only If you have good equipment-and a fussy appreciative ear.

A line conditioer or 2 will treble you enjoyment. Is it worth it to you

Sabai, you might experiment with an Equitech 2Q. Their winding method is patented for "balanced" power and I found it to far surpass my previous medical grade isolation transfomer. It provided delicacy and nuance contributing to the musical 'feel' for all types of music. I'm predominantly classical and jazz, using Spectral Reference gear (which long ago I assumed should not have needed isolation & conditioning--was I ever wrong; I didn't know the quality of Spectral until I had some superior ac conditioning. MIT, Equitech, Sound Application)
I would experiment w whether your sound is better w Triton before or after the 2Q. Important.I have also found a Sound Application conditioner provided "sublime" conditioning for my digital. Remarkable naturalness, ease, flow..sweet sound like vinyl.
