My experience using SR power conditioners was not very positive. They did not do much to improve the sound to justify the cost. Also they offer no surge protection which is important to me given the amount of lightning in my area.
I own other SR products including their grounding system and various room acoustics products, so in theory the combination of products should have yielded audible benefits.

I have had the most success using Shunyata and Audioquest power conditioning products which have always produced great results.

Get over it. I can't make much sense of Shunyata's technology descriptions either. But their stuff works. That is why I have 7 Sigma-X power cords and two Denali power conditioners. One is a Denali-X and the other will be upgraded soon. I also have an Altaira chassis ground hub and Sigma-X grounding cables.

Well the Delta-X which is within my budget doesn't look too bad. Something to consider.

I am curious to your thoughts on the grounding system. I'm also in a battle to solve this problem, especially with my turntable which seems to have good days and bad days in terms of how much 60Hz ground loop I hear and to what spaghetti mess of grounding cables I try using to mitigate it.

I did find that switching to a Nordost Blue Heaven RCA was a huge improvement. Probably the best upgrade to it so far.

I do not think the SR grounding system will do anything to resolve a ground loop or hum issue. It is more about sonic benefits which are system dependent and also create a spaghetti mess of cables. While there is some audible benefit I am not certain the cost is worth the limited sonic gains.
Given current market choices I would most likely choose Shunyata’s offering over the SR.

How long is your run from your TT to your phono-pre ? The shorter the better. Your 'hum' may in fact be entering through it.

try this trick, wrap your IC (TT > phono-pre) in aluminum foil, if that eliminates it, you've found your answer

It's pretty short, distance wise, maybe 4ft. I have a 6ft cable I am using. I will try the aluminum foil trick and see what happens.

6' of IC in that connection is too long IMO, remember the signal traveling through it is extremely low and susceptible to interference more easily than any other. FWIW my length is 1/2 meter in that run

My friend recently added the Shunyata grounding system and it made quite a difference. The difference was noticeable putting the difference into words sort of difficult. Things are more in their own space, a new level of what I'd call realism and more quiet. It's funny how you don't really notice noise until it's gone. No one would ever say the system had noise, it's just somehow quiet became more quiet.
