I should be receiving my first Spike pin very soon (GOT). I have upgraded speakers on my SAM Sterns and I dig the difference they make, especially on Met and IM.
I've read the Spike pins have a new sound system which sounds much better that SAM pins right out of the box. So, are FF or PP speakers a similarly worthwhile upgrade on Spike, or not really needed?
I'm about to order a shaker motor and need to decide whether or not to add the speaker kit.
