I too have the BPT 3.5 Signature. Make sure you give it the full 2 weeks for full break in, although I would say it will be 90% there after 10 days or so.
I have been curious of the same question, and I think I remember seeing something from Chris on his website. www.b-p-t.com and I think it is under "tips" and he names a few power cords for further improvement.
I would have tried already, but as you state it requires a 20 amp IEC. If you decide to try anything let me know. Perhaps I will give Chris @ BPT a call myself.
Good luck & keep us posted.
