Well because I'm a perfectionist when it comes to sound tonality I have since changed to the cheapo thin full foams (also cut into donut) that Golov suggested to me awhile back. They are like a rougher textured VE monk thin (in black) but they block just a tiny bit more sound thus taming the harshness of the treble slightly better whilst retaining the sparkly sound that was lacking with heigi or full ve monk thin foams.
The sound is absolutely perfect now on my stardust since the thin black donut foams give the right balance of bass, tamed treble, mid thickness (not too much as before with heigi/full monk thins) and most importantly an airy quality that is impossible to achieve on the stardust with heigi foams.
As for the actual cutting process it's very easy (just practice once on a throwaway pair of full foams first). Here's what to do.
- Grab a small scissors that's sharp enough to cut with the very top point, make sure the blades are smaller and you can make precise cuts.
- holding the foam under light, with the full front side facing you, you will see through the foam the outline of he circle cut out on the back.
- Stick the scissors through the front gently and start cutting around the outline matching the cut on the back.
- make small cuts and rotate the foam each time until you have a full circle
Voila! now you have yourself a thin donut foam for ultimate clarity.
I'm not using the ve monk donut of the stardust anymore because it was too harsh on the trreble. The foam quality is better on the ve monk the cheap black thin foams, but the sound balance is better on my current configuration.
