You have a wonderful amp in Kara's 845 based tube.
A lot of things that can be tried at your new house before changing
amps. Have you tried the Psvane WE 845 or Elrog 845 tubes? Also four Synergistic Research products might be worth auditioning-
1.The Tesla SE wall outlet
2. The Black fuses
3. Placing their Electronic Circuit Transducers (ECT) on the amp
4. Room treatment products - the Atmosphere, and UEF acoustic panels.
All the above are available with a return policy. I use them and think they allow one to exactly dial in the sound one is searching for.
They have allowed me to to become very happy with my SET amps.
Best wishes on your audio journey.
