How to upgrade "power cord" on turntable with wall wart?

Yes, can be good for amp and preamp, but for turntable power supply it doesn’t matter in my opinion.

You can upgrade tonearm wire instead, external phono cable (or cartridge if you want huge different in sound)

power cable for turntable is the last thing, really

Quarantine neurosis combined with Audio neurosis.

Make sure you replace the factory cord of the new power supply to the table, with a made in USA product. The electrons are being ruined by the made in China supplied item.

All goofing aside, the Project Xtension is a fine table. An appropriate cart and phonostage(with a nice cables if you insist) should be all that's needed.

If it doesn't, sell everything and listen to your Iphone thru Beats.


Obsessing on room and speaker placement is where to consider  upgraditis.

My very first mod was to hard-wire a power cord to the motor of a Basis turntable. The first step in proof of concept, to determine if such things even matter, and if so then how much. The improvement was immediately noticeable.

Exercise caution here, mikepaul, there are way more people with opinions than experience, and even more with way more opinions than listening skills. Logic and reasoning, won’t even go there.

Well maybe for a second. Long enough to point out if things outside the signal path can’t matter then why does the turntable matter at all? Platter, bearing, tone arm, motor- whole thing is outside the signal path. Yet someone with no experience just said emphatically it can’t make any difference.

Inside the wall wart you will find the simplest of simple power supplies. A transformer, couple of diodes, maybe a cap. Probably on a flimsy little circuit board. Not much.

Each one of those cheap little parts contributes to performance. Its not just the wire. Its all of it.

My suggestion is first go check out my system and read the description and comments, so you will know I know what I’m talking about. https://systems.audiogon.com/systems/8367 Notice the mods done to the Active Shielding MPCs. These are almost exactly the same sort of wall wart. All the same principles apply.

Then once you have a handle on it open yours up and have a look inside. Then either DIY or maybe take some pics and message Michael Spallone. Or me. Whatever you do, understand that yes indeed this will make a difference.

Please recall what type of power cable goes to your outlet and what type of outlet it is, something special? What's the point to change 1 meter of the power cable from turntable motor to the outlet if the rest of power cable is just regular power cable you can buy very cheap. There is no audio signal goes throught turntable motor, so it is not the same case as with the amps/preapms. 

If you care about pure electricity then you have to change cables in your house or in your flat. Or maybe power conditioner, pure energy ??? Your own electro station? ))

It makes a difference.  When I bought my Technics SL1200G I started with the supplied power cable.  I had Rob Fritz from Audio Art build me a cable for the turntable.  Once I inserted it into the system, there was an immediate and noticeable increase in PRAT. Going back to the stock cord, the PRAT diminished noticeably.
