Amplifier Power tubes - important to sound?

i replaced all the small tubes on my mono amplifiers and now I'm left with replacing the stock Power tubes, kt88.

I like what I hear with 12 new small tubes - telefunken nos 12ax7 and 12at7.

Now I am left with replacing 16 kt88 stock JJ tubes. will Probably use Siemens 6550 nos.

How much will this impact what I hear do you think? I recall hearing that power tubes don't make that much of a difference.

The donor amp camp with some JJ’s. Amp was very much missing something with the JJ’s. Ordered a pair of The Tube Store preferred series 7189’s. The amp changed completely in its sonic presentation. It now sounds how I hoped it would sound. But, as a single ended amp, swapping out a tube in this simple a circuit, will showcase tube differences kind of dramatically
