Mcintosh C2600 preamp tube upgrade

I recently added the new McIntosh C2600 tube preamp to my system. It's paired up with the MC452 power amp along with Sonus Faber Elipsa speakers and Transparent interconnects/speaker cable.
I"m looking for some guidance with regard to upgrading the tubes in the C2600. Should I, or shouldn't I ? 
Also, what brand should I look for and where should I buy them. And finally, is this a diy upgrade or should I have it done at a audio shop? 
I appreciate any guidance all you audiophiles can offer

Great question, and I don't know. It would be stock Mac tubes, that I'm told are average at best.

Tube Complement

6 Tubes, Five - 12AX7A and One - 12AT7
(viewed thru the Top Cover Window)



Does not say what goes where so there is a difference from the C2300.

I wish I could be more exact but have not seen the C2600.

Congratulations.

When I had the C2300, two 12AX7A per channel for analog, MC and MM inputs were used so if all you wanted to change were the analog inputs, two 12AX7A were all that was needed. It is an easy swap but for your first time, you need to be slow and methodical.

Looks like one 12AX7A and one 12AT7 for you but I don't understand how they are utilized.
