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!

Any word on a stand alone preamp from LTA?  I thought they were working on one?
@admranger 

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. 
@zek4u 

im sure it will be quite a bit more than the MZ2. I will stop in again within the next couple of weeks and ask Mark about the MC option. I’m interested in MC as well. Mark did say the David Berning designed phono stage will be very good.
I almost Forgot. I removed my ZOTL40 and installed the UltraLinear in my listening room powering my 87db Janszen zA2.1 speakers. I can’t believe the 20 watts can power these speakers this way. Im listening as loud as I like and not close to clipping. As good as the ZOTL40 is the UL is more refined in every way especially the bass. It has a firm grip on the woofers. I don’t think I’ve ever heard a piano sound so real before. I’m just beginning to tube roll the 12AU7 and 12AX7s.
