Primaluna Prologue Two

I have just purchased a Primaluna Prologue Two Integrated and I must confess that I like what I'm hearing so far. The world of tubes is new to me and I have heard so much about how one can tweak the sound by rolling tubes. My first question to which I hope to get a straight answer to is?. Are the Primaluna tubes that come with the unit bad to the point of warranting a complete tube change. Looking at the Upscale Audio site under tubes the primaluna tubes are on par with many others in so far as price. Second question if there are any owners of the Prologue Two what tubes have you changed and what have been the benefits of the change, also what tubes make the biggest difference. I will eventually like to change all of the tubes but not at the moment, so were do I start and get the most sonic improvement for my investment.
Thanks

Take this for what it is worth as I don't have your amp - to my ears the Gold Lion KT88s in yours are more musical than other new issues with the exception of Shuguang Black Treasures - more dynamics (have had both in my Ayon Spirit)

For 12ax7s might try NOS Tungsol 5751s ;For 12au7s NOS RFTs (similar in sound to RCAs)- used them together in a Cronus Magnum; also very much like Mazfa CIFTE in my Ayon

Like Saki suggests probably best to ask Kevin at Upscale
