amount of lead in brass will have a lot to do with how these sound under your speakers because of their q and their specific needs.When I used Audio Points discs and no-name brass discs in combination with *non* Audio Points spikes I didnt hear a difference between Audio Points brass discs and no-name brand discs, so for me in that situation it wasn't worth paying triple or quadruple for the Audio Points discs. I really believe the difference is so small, that spending significantly more money on the AP discs may lead to wishful thinking about their performance boost.

On the other hand, when AP products like brass cone footers are used together with AP brass discs, the results can yield bigger benefits. IMO, the footers play a more significant role in the results than do the small brass discs. Whether the sound difference is significant enough to warrant the higher cost of the AP brass products is up to each listener.
