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

Yes, use the Gold Lion for the main guarantee your CD will sound great.

Update...I've installed the Gold Lions and right out of the box there was a SIGNIFICANT improvement! To my ears the mid's and base are the most noticeable. 
Hard to believe a little over a hundred bucks could make such a dramatic improvement. 
Looking forward to listening after I hit that 200 hour mark!
I appreciate all who helped.

For my C2300 I used Gold Lions in line stage and Telefunken ribs in phono stage.  I have replaced my phono stage tubes with the Mc brand since I now have an external phono stage.

The C2300 enjoys a great reputation. I hope time will put the C2600 in the same positive light. 
I only upgraded the line stage because I only have CD player for source equipment.
Im curious about your thoughts on burn in time. Some say as low as zero hours  just warm up for 10-15 minutes prior to use, others say as high as 200 hours.
