Just got the 3S and all I can say is that sonically, its indistinguishable from just using the Sig 30 alone aa. At first, I thought I heard a difference, but with rapid switching of the interconnects I found out it was all in my mind

. I really can't think of anything else to say about it

other than it looks almost regal sitting atop the Sig 30 with the Herbies Tenderfeet giving the perfect amount of spacing and isolation. Having identical dimensions and look add to the effect.
Vinnie, you've done it again

.
Thanks!
