I use to get them from myesound or meniscus audio when I needed 1/4 - 20 but neither carry or are sold out.
So where are you finding them these days?
I am spiking my LS90s and want a good brass spike to use on them.
Let me know what you are using these days.
Looked on ebay, partsexpress, dedicatedaudio, amazon and a few others and just not seeing what I want.
Myesound or meniscus audio like spikes is what I prefer, just raw brass spikes.
