Cost Effective System Improvement?


My hobby is to get the best possible sound IMO at the lowest possible cost. My system:

Tekton Electron Speakers - Upgraded
Doge 10 Tube Amplifier (generally 30WPC in Class A) with Psvane KT88-TII, GE 5751 3 mica black plate preamp tubes, and NOS Mullard CV4024 phase inverters.
Denafrips Pontus DAC
Canare 4S11 Speaker Cables

I listen only to TIDAL Premium through Bluesound Node 2i using the BluOS on an android tablet. I often listen to vocals and use the following as test tracks:

Vaya Con dios “Don’t Cry for Louie”
Dave’s True Story “Chasin’ The White Line Down”
Dead Can Dance “The Wind That Shakes the Barley”
Harry Nilsson “Without You”
Glen Campbell “By The Time I get To Phoenix”

I would like recommendations on what I might do for a cost effective improvement. I would consider spending $2-4K for different speakers or amplifier. The speakers and/or amplifier would have to weigh less than 80lbs. My back is 75 years old.

I appreciate your recommendations.

My "Cost Effective System Improvement" is totally without cost, but only to those who are regular wearers of eyeglasses.  If you fall into this category, try this -------.   Sit in your "sweet spot" and listen to your favorite music with your eyes closed.   Midway in the piece, remove your glasses and hear the difference !   It always amazed me that audiophiles, who are conscious of every reflective surface in their listening room and spend thousands to adjust and regulate room acoustics, would wear a pair of "reflectors" only inches from their "receptors" !   Try it !  It's free, cost effective and a really big improvement !
   Both Sennheiser and Neumann have developed head-shaped binaural microphones and neither of them come with an eyeglasses option !  I'm just sayin' !
