I don't believe anyone would hear "SIGNIFICANTLY" better sound reproduced from any "one" tweak in their audio system. I do, however, receive more information through my speakers having added the TORUS RM-20 power conditioner, (two years ago) whether the source is from my TT or CD transport. Simply more information. One thing that should be determined in a forum such as this one is: Does a tweak give you "better" sound or just "different" sound. A difference in the information you hear can be quantified, but is that difference actually "better" ? I just added an Audioquest NRG-Z3 power cord from the TORUS to my amplifier. This was added as a request from a retail audio boutique owner I've know for many years. I use good quality cable for interconnects and I terminate these cables myself so I'm not one to purchase expensive cabling. HOWEVER... this Audioquest AC cable created a very discernable change in what I was hearing through my speakers and I'm still (after a week) not sure if the change is better than I was hearing before, but it's certainly different and I don't know why. To be truthful, I didn't want to hear a difference. I wanted to return this cable and get the refund promised if I wasn't convinced that it improved the sound. Now it's a conundrum ..
