I use a Mothership 01 with my Soloist 3XGT and Composer 3XP. This rack unsurprisingly pairs well with these Burson products. This stack looks great and frees up valuable desk space. Assembly took a bit of thought, mostly because the unit relies somewhat on gravity to stay together, I don't expect to flip it upside down anytime soon but wouldn't be surprised if it were to come apart if I did so. Overall, I'm satisfied and glad that I have this rack for my Burson stack.
