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!

thanks for your input. Those ICs are indeed expensive compared to the value of my components, but I will keep them in the list.

I'm surprised nobody has chimed in in regards to tube rolling, vibration control, or power cords. Anyone?

Thank you!

Thanks all for the input!

Tvad: I recall an older post of yours where you stated the LL2 was rather inmune to power cord upgrades. Maybe that perception changed after trying the Dominus?

For those who noticed an improvement from tube rolling: which tubes should I roll first? The 12AU7, 6922 or 6X4?

I'm certainly going to try it stock first and then go from there.

Keep the feedback coming!

Tvad,

Please don't take my reply as a challenge. It certainly is not! I appreciate your input. I have been digging the archives for info so I had some background prior to posting.

I went back and searched, and searched, and I could find nothing! I was going nuts! I was about to quit digging when I remembered I had also searched the asylum, and there it was: June 22, 2006. http://db.audioasylum.com/cgi/m.mpl?forum=amp&n=97660&highlight=tvad+ll2+immune&r=

But then again, I did not mean to challenge you. Changing points of views based on further experience is good, in my book.

Regards,
Horacio

Hey, Tvad, I have used that "well...I was drunk at the time" line, but in different settings...mostly related to ladies and stuff. Oh well!!

I take you were feeding power direct from a dedicated line thru the Ferrox, right? (ie, no power conditioning)
Did you also used Purist Audio ICs? Did you noticed much sensitivity to the type of IC used?

Thanks!
