IEC inlet socket

Hi, I would like to ask the following. My DCCA power cord that has a Furutech FI-25 gold plated IEC plug on one end. Usually this plug has a nice tight fit when inserted into an IEC inlet socket but when I insert this plug into the IEC inlet socket of my Lamm L2 Reference preamplifier the connection is not tight but rather loose. Does any of you know what IEC inlet socket Lamm uses? Which IEC plug is slightly oversized so it will have a tight connection with the IEC inlet socket of the Lamm? Thank you.

wrap electric tape around the IEC cord side.
Alas, an all too common problem. I ordered my new amp with a 20 amp input IEC, and will transition to same throughout my system. Not only does the housing fit snug, but the actual connection is improved allowing for better current transfer.

Wattgates are pretty good as are Tek Line Cables new Reference Line. I just switched to his micro Reference Extremes ($500) and am quite happy. He sells direct saving us all money
Hi Chris,

Are you having the same problem with any of your other DCCA power cords or just this one??

Most of the aftermarket IEC's by Furutech or Wattgate are extremely thight. I wouldn't wrap any electrical tape as mentioned above to create a snugger fit... as your only asking for trouble when you try to remove the PC.
The IEC connectors on the aftermarket cables in my system were loose, too, and searching AudigoN for a solution brought me to this thread and one from a few years ago. The two most promising suggestions (aside from upgrading the connectors themselves) were adding shrink tubing or electrical tape to the male IEC connector.

Wanting to avoid the gooey mess the glue on electrical tape makes as it degrades sent me rummaging for some uber-sized shrink tubing bought for a long ago project. The tubing wasn't found, but the search lead me to what may be a good solution: Teflon tape. The same stuff plumbers use to keep screw on fittings from leaking. Well, supposedly Teflon is better than PVC in building cables and the tape has no glue. If the experiment didn't pan out removal would be easy and clean, so why not?

Carefully wrapping about 24" inches of tape around each male IEC connector, making sure to keep it away from the electrical end of things, worked like a charm. No more sagging IECs and what appears to be a more secure connection.

It could just be my mood or satisfaction from solving a puzzle (like my car being faster after I change the oil?), but after an hour the sound seemed a bit more relaxed. I'll check back if something more realistic crops up. The experiences of anyone else who gives this a try would be of interest.
Good idea with the teflon tape, most likely helps with damping a bit as well.
Or Heatshrink tubing...
Most IEC plugs are tapered somewhat and are usually too long. The Marinco plugs are this way, as are many others.
What I have done on most of my cords is cut or sand off 1/8 to 3/16 inch of the plastic end. The internal prongs will now contact further in on the chassis socket and the larger part of the taper will make a tighter hold. This takes a little work, but it is permanent.
The 20 amp pieces are the way to go, as mentioned previously by another member, but that requires even more work, and an adaptor for when you want to try other cords.
