I haven't heard the HE-4 or the Polaris, but I've used both the Mini-x and the Project Ember with the HE-400. The Mini-X is pretty formidable in the bass, but I find that the Ember has ~95% of the bass weight (tube dependent) and that the increase in openness and resolution is well worth it. They are tied for extension (excellent), and I think the Ember is a bit better in the texture department.
I could be completely wrong here, but it looks like the Polaris and Ember have the same SS output stage? Based on the fact that the output power vs impedance graph is essentially the same for both? If so, I would expect the Polaris to have pretty similar bass performance, maybe a little cleaner than the Ember considering there's no tube. But that is all total speculation.
Anyway, the Mini-x was fun but it had some congestion and graininess that I don't miss.
You totally nailed it, I completely agree with all of this.
Yeah, Polaris has the same output stage as Ember, basically just the SS half of the Ember hybrid. Soundsgoodtome has had both at the same time though, I think he preferred the bass from Polaris.
