Theta Enterprise or Ayre V1x with Vandy 5A

Thank you. I'm listening with the Ayre V5x and it is truly outstanding, but I'm just finding it a little lean in the midbass. I was hoping the V-1x might improve upon that one shortcoming as it has a much beefier power supply. At the V-1X's price however, the Theta Enterprise now enters the picture.

Thank you all so far for very informative responses.
