Love your system!
I have done the A/B with glass vs. acrylic shelfs in my Quadraspire cube series stuff (which is not quite as good sonically as the Q4, but the only thing that fits and is wife approved for my living room). There is a very notable improvement with the acrylic, at least for the shelf you put your digital source on. For amps and such, I think there is a significant decrease in the degree of benefit, though one is probably still there (I didn't do this A/B specifically, only with my source). Given the quality of your gear, I think buying at least one of the acrylic shelfs for your Ikemi will be a very good investment. It should cost around $350 or so.
