Linear Tube Audio- Any feedback on their amps/ Preamp?


I recently was told by another member about Linear Tube Audio as they are using David Berning's designs (approved by David) and are made in the USA.  The Micro ZOTL 2.0 pre has just received great reviews and they also offer the ZOTL 40 and ZOTL 10 amps.  I would really like to get some feedback from someone that owns the pre and one of the amps.  Thanks!

Ditto on the MicroZotl2.0s. Fantastic peice for the money. I have it paired with an Aurender A10 and makes for a solid front end.
Mark Schneider (owner of LTA) told me this and I don't think he'll mind me quoting him:

"The ZOTL circuitry is complex and like no other tube amplifier. It is an advance in tube technology. Which is why it sounds more musical and realistic than almost all others, and certainly anything in its price range. One of our clients just replaced his $16K Pass preamp that comes in 3 pieces and his $27K Pass power amps with a microZOTL and 2 monoblocked 40s....and says they sound better."

My current setup:

Melco N1A server
Exogal Comet plus with wywires umbilical cable
primaluna HP integrated with SE black fuse

Running russell k red 50 monitors and swap with Graham Chartwell ls3/5.

i have heard the micro zotl 2.0 at captial audiofest last year and after finding this thread, I am definitely thinking of trying the ZOTL40. Possibly using the Comet dac as preamp until maybe getting the micro 2.0 as preamp as well. I'm guessing from all the positive results I'll have no objections? Also see a lot of fellow gold lion kt77 lovers here which is awesome. 

Thanks in advance for the feedback. 
@kddusing - if you're nearby, Linear Tube Audio is located in Takoma Park, MD, not far from where CAF is held. They have a show room so you can go by there any day for a listen. I stop in frequently.
Their preamp my brother bought and has several units 3x as much thst are not as good. 
And their Lps+:external power supply is incredible. 
It takes the Very good D-1  Lumin digital  12-13v external power supply and makes it exceed their T-1  3x the money. The ps and get the better wire harness, 
And replace fuses the 2 fuses. 1.6 fast blow 20mm Hifi tuning.  The synergistic 
Can be too rich .in a ps you want the neutrality. $700 retail .The preamp ask for a bigger case and ,Khozmo shunt attenuator 63 step with relay,and remote 
Around $2600 with extras .
