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.

This is the greatest place to buy tubes in the entire whole wide world. I sure he's good, but unless he knows what gear you are using, how does he know what the tubes will be operating at?
