If you are going to prise open the wall wart . there is not much point .. all you will find inside is a transformer.. The rectification and smoothing is done on the phono amplifier PCB....

Don't open the wall wart.
It may be double insulated. That is a guarantee that it is safe from mains electric shock even in the event of a fault.

As Andrew said, the rectification and filtering is not in the wall-wart. Replacing it does nothing to help you.

Some time ago PS audio found that the transformer before the bridge would effect the sound even though the current demand was far below the transformers output . Given that if you can get a 17 or 18 volt ac output transformer cheap try it and report back . If the power supply in the box is very good there may be little if any effect. Thus do not spend a lot to try a different ac wall wart or transformer . Regards

My personal opinion is that these sort of things are snake oil.

Something that is well designed should expect to see some sort of trash on the mains and be able to deal with it.

That a big if . It appears a lot of power supplies are not designed to filter out the non primary freq. from the ac line. In a private conversation with Tony Cortasman after he review some filters I ask if as a defense contractor was his ac secured as well as the phone lines . He said of course then I pointed out the the ac line was so heavily filter to prevent spying on his activates related to the DOD that there was no noise on his ac line. Since most of us do not have secured ac coming in to our homes a line conditioner can have an effect.

True. But, if the line conditioner has an audible effect, the designer didn't do their job when designing the equipment. That's not acceptable for a piece of "audiophile" equipment. If it's a cheap piece of equipment, its own flaws will probably mask the line conditioner's effects. At least that's my opinion about it.
