I thought I will make my last post as a 500+ head-fi'er a special treat to y'all
Here are some macro/micro shots of SA6 instead of the more common computer rendering you will find on the web.

All the ports:
Bass-; Bass=; Bass+.
Treble- (yellow); Treble= (green); Treble+ (gray), Treble++ (black).
Notice the Bass+ port has a very small hole in it (more on review)

Non-animating presentation of the VQ system

Back side view when all the ports has been inserted.

Front side view when all the ports has been inserted.

Full assembly, plus some finger print smudge

Cable head, notice the clown color I painted for L/R (more on this later).

Y junction and the headphone jack.

The case, note the secret compartment for storing a set of bass and treble ports.

[
Update] Using a small soldering iron, I burnt a small hole (1mm deep) on the cable head and painted the blue/red indicator color for L/R channel. Now it looks better than ever.
