Hello,
I had the same problem a while back. Rather than making permanent mods, I bought some banana-type adaptors from Esoteric. These are a two piece connector in which the spade is sandwiched between the two pieces. On the end is a banana-type connector. Monster Cable (may still) sold their version the "X-Terminators" which is the same thing. Audioquest also makes some which are a different design but do the same thing (try Audio Advisor-I saw them there recently). I noticed no signal degradation whatsover using the Esoteric connectors with a set of Cardas speaker wire w/rhodium spades. Good luck!!
