I've just recently gone through this, as I'm in the process of doing up some cables for my Mac Amps.
I myself ordered 3/16" Audioquest Spades from RamElectronics, they come in two sizes for up to 14ga, or up to 10ga, and the cost was reasonable enough.
The best spade lug I've seen out there is the billet machined Cardas CMSS, and these generally go for around $11 ea, but not appear to be crimpable, and would need to be soldered.
One has to weigh the advantages, disadvantages, and costs of adapters versus the correct spades.
I can understand going the adapter route if one perhaps has very expensive cables terminated in another fashion, and has future thoughts-wishes of an Amp upgrade that won't have these issues with narrow Barrier Strips. mark
