@regismc , based on specs Statement linestage should be fine match to Hyperion. Statement output impedance 500 ohms, Hestia 400 ohms, Hyperion input impedance 22k, both well matched based on amp input at least 10x higher than pre out. This is by far the most important spec for pre to amp matching.
Output to input sensitivity of Statement to Hyperion is also close to other amps I use with Statement, Coincident Turbo 1v, PL Dialogue Four 880mv, Hyperion 1.8v, Hestia does have much lower output voltage than Statement. Still, I didn't have to run Statement at extremely low range of volume selectors, yes, a bit lower than other amps, Also, the Statement doesn't use volume potentiometers, transformer based volume control doesn't have favored portion of range. Therefore, Hyperion was used within parameters that would allow it to perform at it's highest potential. I stated how I used Hyperion and how it performed in my system, I stand by my comments. As to how it will perform in other systems, I can't say.
