Will an Isolation Transformer Help My Digital?

@lak,
Always appreciate your participation. I found a thread where you speak to using an isolation transformer for the entire audio system, as you have done in your own house.

Do you have any thoughts on using a iso transformer on the front-end of my system if indeed digital noise is being introduced?

Lowrider, I'll bet the wall-wart is a switching power supply. If so, it may be feeding noise back into your wall. Why not try an old laboratory power supply capable of the same voltage, instead of the wall-wart? "Old" being the operative word, before switchers became the order of the day.

Just a wild guess.

terry, I'm sure your right since it is a switching power supply. I plan an upgrade, but that's not a bad idea as a test. Too bad I don't work with the bench tech guys anymore.

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.
