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.

 I have the rogue Apollo monoblocks which use 12 Kt88

I have 3 sets of tubes. Golden lion  Electro Harmonix Kt90 and  Kt120.

The 120 are colored in my application.

The kt90 and sharper and firm the gold lion I give the nod to good luck
