Upgrade: Terminator Plus or PGM156

I stream TIDAL into a green computer optical rendu into Denafrips Pontus II, into a Coda Csib SS integrated or Doge 10 integrated tube amp, into Q Acoustics Concept 500 speakers.

For my next upgrade I am considering either a Denafrips Terminator Plus or  Puritan PGM156 Power "Conditioner". 

I would consider upgrading the tube amp if I could get one that I might like better and weighs less than 75 lbs. Budge would be <$10K.

Any recommendations would be considered.
