High-Rez is relative to ones perspective. Unfortunately I’m unfamiliar with Hegel or Silverline. I’m sure they are great to capture a fellow audiophile’s ears. So I can’t comment on these pieces.
Using the Jay in my secondary system, I perceived a slight improvement over my Avatar in area of micro dynamics and few others. Both transport shares similar characteristics. Furthermore I experienced no room node problems due the fact that my Kharma CRM2.3FE doesn’t reach that low.
But in my main system, the twin servo-sub-towers excited my room with new found authority which caught me by surprise. My system measures flat to 18hz but never did I need to retune my system due to transport swap. I cite this as a testament to the Jay.
So if your system doesn’t reach that low, you’ll have no concerns. As jafant sez, enjoy the music.
