LTA Microzotl Preamp Level 2 upgrade

any experience among GONERS getting this wonderful preamp upgraded?
I have had the upgraded Microzotl preamp for about 6 weeks.  Using unbalanced cables it was a nice improvement.  Using the balanced inputs absolutely sent the sound to a new universe.  Speakers totally disappeared in the room.  Incredible imaging, wider and a bit deeper soundstage, increased details.  Well worth it.  A very nice step up indeed!!!
which amp is the Microzotl connected to?
Saving my pennies, will do next year
