In Reply to: RE: Strain relief - IEC posted by setamp on August 13, 2014 at 09:40:04
You are on the right track. Common 15A. IECs are a degrade sonically to a 20 A. IEC with a DC 2A3 SE amp, so....I recon hard wiring the AC cord to the chassis will be the best sonically.
The IEC when removed leaves a large hole. I know of NO way to easily plug it up.
I might take a piece of tubing, cut open down its length, and use it over the hole's edges, so the incoming AC wiring does not chaff on the edge of the chassis' hole. I'd use one of the two chassis' empty IEC mounting tab holes to hold a beefy "P" clip which will strain relief and hold in place internally in the amp the hard-wired AC cord.

Quality IECs do not degrade sound quality. The OP is likely embarking on a difficult project for no sonic reward.

Sorry, nope.On any really good system, a 15 A. IEC into an amp is an easily audible degrade, versus a 20 A. IEC.
Also, a hard wired, well-soldered connection would be better than an IEC of any type or of any rating, just less convienient.

No, you're wrong. Say it a thousand times, it still won't be true, wait a thousand years, there still won't be any scientific basis for such statements.

There are many reasons a 20A is superior. Look at both and compare the surface area. But the real improvement comes when one compares how they fit and stay "together". I don't know anyone who hasn't had a 15A IEC come loose out of a piece of gear when using 14 gauge or larger power cords. There is just not enough length and surface area on a 15A prongs. All good hi-fi gear should have 20 IEC regardless of its current consumption for superior power transfer and the superior physical connection.
