Signal tube versus power tube, sound impact?


My mono block has eight KT 88 tubes(power tubes) and six smaller signal tubes. I'm using the stock tubes that came with each Mono. I think they are JJ tubes.

Rather than replace them all would it be best to change out the signal or the power tubes? Not sure how good the JJ tubes are but I hear they may not be the greatest.

Some tough supply chain decisions were made during the pandemic. NOS tubes are going to get harder to source every year. Hopefully CJ has a plan for that inevitability.
