The 15A IEC is inferior, that's all there is to it

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.

RE: The 15A IEC is .. I got a 15 chassis IEC from Furutec and it is very good - Smelly_Socks 12:20:47 08/21/15 (0)
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.
