A better lamp cord for my stereo equipment?

As for resale value generally no change in resale value for components with a nice job IEC on back in place of hard wired zip cord.
I agree the liability for a professional would stop a lot of this being done by them.
SO many folks are lawsuit crazy.. It is just not worth it to take any chance for a customer. (do them a favor and they bite you in the arse with a lawsuit)

I own an Audio Research SP-15 I wish I could get in gear and swap the wired in AC for a IEC. Lazy.

If anyone knows of a little box to place the IEC dangle mod..
Cutting the hardwired AC cord just outside the cabinet, then adding a IEC.. if only someone made a small plastic box to place the IEC into, which just covered the back of the IEC and screwed the IEC into. With a hole just big enough in back for the zipline AC wire..

Here are some cable mount IEC connectors

Also I just spent 15 minutes looking for the legal aspect of this issue and could not find a single case of having to re-certify either UL or CSA for components with the power cord is changed by a technician or owner

Having said that - CSA and UL really only applies to companies making devices for sale in the respective domains and not after sales mods made by customers

However, If a technician changes the power cord they immediately become liable for that repair - and as we all know, power supplies can catch fire - whereas changes to an internal circuit board will probably only fry that board, which is why most technicians will not touch a power supply - except the really competent ones

Also - if your insurance company discovers you tinkered with a piece of electronics after it’s purchase - and it actually caused a fire - you would probably not be covered.

Hopefully the fire would destroy all evidence :-)

Realistically - the number of components in the world that are constructed by DIY enthusiasts must be huge and with the right due diligence they are probably completely safe.

Using the connectors in the link above is comparable to replacing a switch or plug on a table lamp.

If the plug is polarized - for sure, care must be taken to get the polarity correct - otherwise there may be a risk of electric shock

As for UL and certainly CSA - I have encountered cable products having both of these certifications where the polarity was incorrect - which makes me wonder exactly how stringent they are at enforcement.

Next time you purchase a power cable from Home Depot - check the polarity - it might just surprise you :-)

Never had good results with ferrites on Audio Equipment whereas I always had good results with ferrites on appliances such as fridge, TV, computer, etc.

Just leaving this here in case somebody wants to try it.
