New Linear Tube Audio MicroZOTL Preamplifer


MicroZOTL Preamp vs MZ2


Greatly Improved house sound and more of it.


I have been using the MZ2 as a preamp with the ZOTL40 powering Janszen zA2.1 hybrid electrostats. The Micro ZOTL was originally built as a headphone amp, and then David Berning tweaked the design for use as a preamp (the MZ2 that Mark Schneider currently builds) and what a good one it is. A huge Audio bang for the buck. As good as the MZ2 sounds, it’s a bit of a Swiss Army knife product and not a dedicated preamp with full functionality. Enter the Micro ZOTL Preamp.


I am lucky enough to live near Linear Tube Audio and Mark let me borrow his prototype preamp for a few days. The new preamp has a wider, more clearly defined sound stage and more sparkle at the top. The bass is just a bit more real sounding. There is smoothness, a little smoother without losing dynamics. I can’t explain this but could the MZ2 have been a little grainy sounding?


The piano is sounding more real than ever. There is more clarity in the sense of having more space in between notes or just less noise? Not that I could ever detect any audible noise before with the MZ2 but the background is darker. I guess more real, more in the venue feel.


So the flavor is similar, improved and enhanced in purity, refined, actually more refined. I even tried the carefully selected NOS tubes that I use in my MZ2 for comparison to discover that the NOS tubes that come with new pre are pretty darn good. I think Mark has optimized this circuit design as far as it will go and the more I listen the more I like it. I had to return this one but I have already ordered one when the production models are ready.

I got to hear this at AXPONA and it was really something special. I have the M2Z as well and it definitely seemed like the new model had all of the positive traits from it - just done better. Very impressive.
My MicroZOTL Preamp is on the way and glad to move on this before the price increase.

I just got this from LTA today:

With all beta testing and feature enhancements now completed, Linear Tube Audio is excited to launch the new MicroZOTL Preamplifier this week. We are extending our pre-sale through Wednesday, July 18. There are only six days left to get your MZ Pre at the temporary pre-sale price of $3850! The price after the pre-sale will be $4450.
 
Our fully realized MicroZOTL Preamplifier has been upgraded from 64 volume steps to 100 steps – with the smallest step ¼ the size to ensure precise control at low levels. Additionally, we have upgraded the volume control to ceramic printed circuit boards are now using OHNO wire on the output to further improve the sonics.

We look forward to sharing the newest addition to the ZOTL family with you. As each amp is built to order, please allow for 10 days to 2 weeks lead time.

Pre-order today!


I live in DC and helped Mark at LTA when he was making refinements for the preamp. I already own their MZ2 and Ultralinear amp. The new preamp is definitely a step up from the MZ2 especially when using NOS tubes. It is quite a bit more dynamic with more detail and a remarkable soundstage. It is an excellent partner for my Ultralinear and sounds great with my Omega Audio single driver crossover-less speakers. I liked it enough to purchase one and should have it in about a week.

im also local and like to stop in on Mark whenever I’m close to Takoma Park. My new preamp should be ready this week I’m told. Can’t wait.

I now have the new MIcro ZOTL Preamp in my system and after only a couple of hours I cant believe how good it is. Everything I said about this preamp in my original post..... well.... it’s better, much better. I don’t know what alchemy Mark has come up with but this pre is incredible. The UltraLinear and this ZOTL Preamp were made for each other. More to come.
