Thanks for the advice. Really helpful

I have the Rackbrute already, got it £100 cheaper than the Mantis, although I appreciate the Mantis offers more HP and better power. I’m banking on the Rackbrute being enough to meet my needs. Although I don’t quite follow how to move the switch and power to gain another 4HP?

On the VCA, it’s difficult to source the Alyseum. Thoughts on either the Intellijel or Doepfer Quad VCA instead? The latter being a fair bit cheaper.
