Will an Isolation Transformer Help My Digital?

Low- on the linear power supply, take a look at the product in the link below. I bought one in part because it was cheap, it has a large toroidal transformer, multiple channels for setting voltage and current limit (with read-outs) as well as a channel with fixed voltage/current. I am not using it for an audio component as such (rather, for one of those Acoustic Revive Schumann resonance generators which may put me in the category of "fringe"/voodoo, I dunno), but it seems like a good value.

Lowrider57,
Short answer, yes a good Isolation transformer can help front end components sound better.
This would also help IMO with or without an isolation transformer: https://forum.audiogon.com/discussions/has-anyone-tried-these-stunning-new-cpt-power-cord

This is a bit long, but worth reading: My power filtration for my entire systems is provided by two Extreme Isolation Transformers (5 KVA each). The power goes from my main circuit breaker panel into the Xentek Extreme Isolation Transformers and then into a sub-panel that feeds all eight dedicated AC outlets into my audio systems. The Extreme Isolation transformers have a huge iron core design, noise suppression is -146 and they weigh 129 lbs. each. The isolation transformers actually sit on three 1-1/2" solid brass audio points that are on top of the cinder blocks and the cinder blocks rest on top of three hockey pucks that are on the concrete floor. I hear greatly improved musical response in all areas with no major side effects other than the production of some hum, slight heat and of course any isolation transformer is going to consume additional electricity. The hum and slight heat is not a problem for me since the transformers are located in a different room in the basement. I also think different brands of isolation transformers produce different results and most likely are somewhat system dependent. What works well for one audiophile might not produce the same results for another. The beauty of my power filtration system is I purchased the transformers used and did all of the labor myself. The total cost was well under $1000 (for the used transformers, running 8 dedicated lines and circuit breakers, etc., high end outlets not included). With that said, I improved the sound recently in my secondary system when I attached a CPT 300 power cord to my PLCX0e6 (in my secondary system) and powered my Transport, Dac, and FM tuner and the sound of my front end components were once again improved. See: https://forum.audiogon.com/discussions/has-anyone-tried-these-stunning-new-cpt-power-cord (same link as above).

Lak: a question. Is there some kind of transformer in the box of those Core cables? Is the "output" side delivering true balanced power 60/0/60?
I am also a big believer in isolation transformers and have several, from a smallish medical grade one that I use for my tonearm air compressor to the Equi=Tech 10kVa (which is sitting in storage, awaiting a new property to install it). 

Whart, you ask a great question which I'm not qualified to answer.
I'd love to own the Equi=Tech 10 KVA :-)!
I still own an Equi=Tech Q2.

You could always send an email to Mark at that site or ask that question on the CPT discussion forum here on Audiogon, or phone him. When he sees your question he will answer. It's my understanding that somehow it's balanced power, but that's the limit of my knowledge. LOL!
