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

Congratulations on purchasing a PL2. I have been using both the PL2 and PL5 in my systems since 2005 and I have not felt the need to change amps at all.

Changing out the preamp tubes (12AX7 & 12AU7) will make the most noticeable difference at this point. Speak with Kevin. He will undoubtedly recommend something like NOS tubes from Mullard and Sylvania. They are worth the extra cash.

I would stay put with the power tubes at this point. Over time you can see if you prefer KT88s to EL34s to 6CA7s, etc.
