Discrete owner here. For sure two Discrete PSU over one. I added the second one a few months later and was floored by the improvements. Hard to justify the $7k cost of the power base with the Discrete. At that point it's too close to the cost of the Premier to justify, unless your dealer has a generous upgrade policy.
Love my Discrete! Compared to dCS Bartok, Lumin X1, and Mola Mola Tambaqui I owned, it's the clear winner for me.
@creditingkarma I use the Renderer and am going to have to try the Gigafoil now!
