Is there a difference? I have a good 20A cable with an inexpensive 20-15 amp IEC adapter. Worth upgrading? I'm a cable devotee, no convincing there, but this one brings out the skeptic in me.

If you are going to use an adapter (and I use one into my Audience AR6T power conditioner), Voodoo Cable makes an excellent product.

+1 on the VooDoo Cable adapter. Works great for me.

I would put a 20A IEC inlet on the piece of gear as ANY adapter will degrade some amount.20A IEC's are so much better and should become the standard. This really has little to do with current handing capability. The amount of surface area and the length/width of the 20A "prongs" makes for a FAR SUPERIOR connection both electrically and as important physically. The horizontally vs vertically mounted blades (prongs) also play a role.
I'm sure many here have seen how easy a 15A IEC can fall out or come loose due to the heavy power cords used today. The 15A simply doesn't have enough "prong" length. Then when they start to fit loose on top of that it's really bad.
If you have a few of both you know. If you don't have a 20A IEC then go to a dealer and plug in and unplug a 20A IEC.

The prongs are thick and well made. The backside uses screws to clamp down on the wire which can be up to 10 gauge (which the Furman REF20i has)
I replaced a 20 amp to my Furman REF20i. Going from a 20 amp to the regular 15 so I can use normal (but large) power cords.
I have zero problems. The connection stays very tight, and is not 'warm' or anything.
No problem.
When I recently had an amp rebuilt by Steve McCormack, we decided the best IEC is no IEC and hardwired the power cable to the amp.
I agree about the 20A IEC being superior based on my time with the DNA 500 amp.
The other consideration that the pro guys like is the powerCON connector. I have those connecting DC power from an outboard power supply to my preamp and the connection is very secure. They have silver plated bronze conductors, which are just about as good as it gets for power.
Yes, hardwired is best. But then buyers would complain they can't upgrade the power cord.
...to find the cord you want to use first.
This was a custom built amp so I would only have myself to complain to, since I picked the cord.
The way it is connected to the amp, I could easily change the cord myself, but it does inhibit cable surfing.
I have hard wired an upgraded cord. I've even hardwired a cord or two direct to the transformer primary bypassing a lot of crap that degrades the signal/sound with great sound improvement. Yes there are risks.....I have contingencies for those to prevent catastrophic failure.

Don't really want to modify my amp. And I design high end electronics packaging for a living,,,
I hear ya. It takes about 30 minutes to an hour with a Dremel tool and soldering iron. I understand many will not want to. I would then reterminate the power cord you have to a 15A IEC, that is comparatively simple.

Using an adapter for any audio device tends to degrade performance, so re-terminating the power cord with a 15A IEC connector would be the most advisable option to consider. If re-termination is not acceptable, use of a premium 20A to 15A IEC adapter with copper contacts rather than a generic 20A to 15A IEC adapter with brass contacts would be a worthwhile option to explore. The relatively inexpensive Pangea Item # PG2015ADP from Audio Advisor with right of return if not satisfied would be a simple device to experiment with. However, the most straightforward option to consider if re-termination is unacceptable would be to replace the 15A IEC inlet of the component the power cord is placed on with a 20A IEC inlet, which would be an electrically safe modification in this case.

I would disagree but thanks. I'd bet the Shunyata process for termination is far better than anything I could do (or many others).
Bought a Voodoo adapter, seemed good.

True..... So why don't you contact Shunyata Research and ask them what they would charge you to change the 20 amp IEC to a 15 amp?
