~1600 LRAs does sound like a lot of fun. However, I believe how you control them depends a lot on what exactly you want to acchieve. I'm by no means an expert, but what I've read is that the resonant frequency of LRAs is very narrow (high Q). Meaning, that if you want them to be efficient, you have to excite them exactly at resonance frequency. This ...

Let go of the 5V -> 0.6V DC/DC idea and design an inverter based on a H-Bridge (or many H-Bridges) feeding a transformer (many transformers). You could then let the inversion step also involve the voltage conversion step (which is a good idea, because DC/DC voltage conversion is harder than AC/AC, which can be done trivially with a transformer). Also, 5V ...
