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!

Man. Ultralinear sounds amazing. Okay I’m adding it to the list. Just kind of shocked the ZOTL 10 powers the P3ESRs. Funny how Enjoy The Music just published a great ZOTL 10 review right when I decide to keep mine. He also seems to be the first state that the little 10 can power less efficient Speakers. I don’t crank my stuff though. Well, stars aligned for me on my April fools birthday. Ha.

From reading the review, what does stick out with my system is the quality of the bass and the dynamics. It’s scope is huge and defined. Transient information is just amazing. So real and I have crappy cables right now. 
Any word on a stand alone preamp from LTA?  I thought they were working on one?

I was at LTA recently and saw the stand alone preamp prototype sitting on the work bench. It’s a full size Fern and Robey built case.  It has a ceramic board and optional phono stage. Mark didn’t say when a production model will be available but it looks promising.
Wonder if it will have MC too.  About to buy a DV 75 Mk. IV. But it might be hard to beat it with the Dr. T mode with my 20X2L. 

Am sure it will be a lot more then the MZ2-S.
