I am using Monster Cable X-Terminators purchased from audio advisor and they don't seem to affect sound quality I tightened them to spades with small needle nose pliers and applied contact enhancer (highly recomended). Speaker cables used are MIT MH-750 Series II CVT Terminator powered by McCormack DNA-2 amp to Polk RT-20P speakers. Let me know how they work for you.
Magnepan Spade Lug Adapters
I just received a fantastic set of Silver Sonic T-14 speaker cables, but they are terminated in spade lugs and my Maggie 1.6QRs have non-standard binding posts which don't accept spade lugs. Supposedly there are adapters out there, but I haven't been able to find any info on them. Do they really exist? Do they affect the sound? Should I just have the cables reterminated? Anyone have any insight? Thanks in advance. Brian
