Better Power Cord for my Threshold Forte?

suggest MAC powercables...inexpensive and make a big improvement.

Mapleshaderecords.com
offers a unique item,
"Clearview Double Helix Power Cord Kit" that you splice onto your chopped short (by brave you) existing pigtail of a permanently attached power cord.
You can call or email the company to find out the real world results of this idea which lets a bit of the original puny vintage cord remain.
I use their power cords and power strips, but never had the courage to chop short a built in AC cord, although none of my permanently attached cords are as rudimentary or needy as what you describe.

Is there a way for me (modestly skilled) to attach either the MAC powercable or the Clearview Helix at the solder points inside the amp, as opposed to splicing the new cord onto a pigtail? Should I have a pro do this?? Thanks again.

Just use an adapter. it plugs into the stock cord, and has the IEC connection on the other end.

Many places offer them... VA Audio for example, or Google for IEC adapters. Online power, I think supplies these too, singles and doubles. I've used and have both the VA Audio adapter, ($15) AND THE oNLINE ONES ($3 - $6), THE DIFF IS SO SMALL IF ANY, i BOUGHT SEVERAL MORE OF THE CHEAPER ONES TO KEEP AROUND FOR BURNING IN POWER CABLES OR TO USE WITH GBETTER POWER CABLES ON NON MIGRATORY CORDS... EX. CABLE BOX, cd CAROSEL, tv... ETC.

If used solely to CONVERT, say from a 20A IEC TO a 15A IEC, or vice versa, Voodoo Cable offers some fine ones right here on the 'gone.
