CODA Continum 8 Imput Impeadence

Hi,
im looking to up my amp game from 2 Parasound A23's
I am interested in the CODA Continum 8 monoblocks, they will be built in the TM chassis without the meters and faceplate milling (not a fan) I am on the verge of pulling the trigger but am concerned with the low input impeadence.

CODA states it as 75K ohms unbalanced and just 1K ohm balance (which is what I will be running)

Pre-amp is an Allnic L-1500 tube with 150 ohm out put impeadence

Does anyone have CODA gear and what pre are you running with it? That very low imput impeadence has me worried

thanks for any guidance or experience!
