Best amps for everything EXCEPT bass

Vandersteen Treo CT speakers. Swarm subwoofer system with two amps. All frequencies are covered and sound outstanding with my Quicksilver V4 tube amps and the Swarm.

So, do I change out the Quicksilver for an Ayre VX5-20? Most of the comments on the Ayre upgrade focus on bass - my set up will benefit from improved bass, but that’s not the focus since the Treo’s aren’t my primary source of bass.

Thoughts, comments and recommendations are welcomed.
