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.

If you like the way it sounds now, stock tubes might be the best budget replacement. It you want more with great top end extension kT-88 Gold Lions sound very good. Yes, power tubes are everything.
