Suggestions to upgrade from Lyra Delos

Greetings again folks:

I've done a bunch of tweaking and fiddling with my Thorens TD124 including a new arm (Jeff Spall), Audio Silente bushings and other minor things.  I love my Delos in general, but I feel like it's missing something.  It's very detailed, fast, tight bass, good channel separation and soundstage (in general, feels a bit compressed front to back) but I feel like I'm missing that 'thing.'  Of course it could just be perception on my part, but I don't have much to compare with so that is the intent of this thread.

The rig:

Thorens TD124 Mk1 w/Mk II mods
Jeff Spall (Audiomods UK) Tonearm,v6
Lyra Delos, with Microridge stylus (original, not rebuilt)
Hagerman Audio Labs Trumpet MC (Loaded at 110 Ohms)
Stax SRM-007T Headphone Amp with Stax Lambda Nova Signature headphones

I'd like to stay under $5K as well and would prefer a similar cost to the Delos ($2K) if possible, but willing to invest more in a different experience if that experience is better.

I realize this is a highly subjective ask.  I would appreciate responses from those that have gone from or to a Delos and what you went to / from.  I'm certainly considering the Kleos or a used Etna (if I can find one in the price range) but again, would like to try another direction to experience a broader range of sound signatures.

Thank you, in advance, for any suggestions.
