Lamm LL2 tweaks?

After a very long search I decided to upgrade my Rotel preamp to an LL2 Deluxe. This should be a HUGE improvement and I can't wait for the Lamm to get home!!!

As I wait I'm already wondering which tweaks others have found most effective with this unit and would like your input.
- Tube rolling: I've seen several posts stating it does indeed react to this. What should the pecking order be? 12AU7, 6922, 6X4? Which tubes have worked best for you?
- Vibration control?
- Power cord: I've seen a post stating the LL2 is inmune to PC upgrades. Do others agree?
- Tube dampers?
- Which interconnects have worked best for you?
- Other thoughts?

FWIW it will be paired with a McIntosh MC275 with rolled tubes. ICs are cheaper Nordost, and my next weakest link is my CD player, and I will likely add an outboard DAC.

Thank you!

I own an LL2 preamp, changed the 6922 tubes for NOS ones and got different but not better sound from stock ones.

I am using a Siltech SPX30! PC and that changed the preamp in a much better way, open, fast and more a more liquid presentation.

No footers so far.
