Personally I would send them back to Audioquest. Otherwise the Audioquest spades are amongst the best I have heard and very cheap compared with the very best spades.
Speaker cable termination
I have a pair of old Audioquest Midnight 2 speaker cables and I need to change the termination from banana plugs to spade lugs. Could anyone recommend where to purchase the spades ? Would the quality of spades make an audible difference ? Can I solder it myself easily ? Is it worthwhile to send it back to Audioquest for re-termination ? Thanks.
