David Berning preamp..looking for suggestions

I am on a look out for a good tube preamp with preferably a reference grade phono stage inbuilt. I am moving from a tube amplification to solid state amplification primarily to feed my Tannoy Prestige with all the power it needs. In the process I dont want to end up in an all SS system which will be too much of a deviation. So I would love to have at least a tube preamp and if possible a tube phono too. I know it may ultimately involve using a SUT but I can take that much of a compromise (if at all). 

I am considering the Berning ZOTL-One preamp with in-built phono stage. There are many reviews of his power amp but not much about his preamp. Has anyone heard his preamp, any impressions (even second hand) would be very helpful.
I have not heard the one you mentioned but I have Tannoy prestige speakers and recently went to a Bottlehead Beepre. With the optional attenuator, upgraded tubes and some vibration dampening it is the best I have ever heard.  After that experience if I wasn't in love with my Herron phonostage I would've went for their phono and used a SUT. As far as amplification goes I use 845 monoblocks and they work beautifully with the tannoys. I don't think I could ever switch to ss. 
I do have great respect for David Berning however and think you would probably also be happy if you went that route.  Sorry for going off on a tangent. 
Pani, any reason you want to limit your preamp choices to Berning? What are your source components?

I suggest you read about Vinnie Rossi LIO configurable preamp and its user experience in Audio Circle.   I don't have experience using LIO but I am using similar volume attenuator (John Chapman & Dave Slagle autoformer) in passive mode when DIY enthusiasts can purchase it directly from Bent Audio.  It replaced AR REF 5 SE tube preamp in my system.

The LIO has an option for autoformer volume control with tube stage - that's the one I recommend.  It also has phono stage option.  It is also upgradable.  Please check it out.
One statement got my attention . A Vacuum tube preamp is not limited
On it's gain vs A  solid state unit. My custom built DHT- Direct Heated Triode
In my opinion and many others is better thrn any mini tubes or solid state units
It is  solely transformer based my preamp currently has Hammond transformers 
With dual chokes in thd power section. The only capacItors  are a. 47 uf     Obliggato gold , 2 Big 68uf oil capacitors, and 2 Audyn True Copper .1 bypass caps. On the Audio side 2 Lundahl transformers .the gain us Fully controlled by the transformers chosen. The Vacuum tubes chosen are classics.
The rectifier tube is the 274b, and on thd preamp section 1 per channel of the 
26 Vacuum tube, and the 101d tubes ,just flip a switch and Taylor your music to
Which tube you like  for that type of music.why  do you think a Single ended amplifier 
Is so pure. In a preamplifier there is No limitation. My preamplifier is under $4k
But will not be beat by Any conventional preamp even at $10k+. Everyone that 
Hears it in action wants one , instruments just sound more real and dimentional.
Also if the Engineer or builder know their circuits well these tubes run very low voltage and last . The rectifier by  nature is the only tube that puts out 
Any noticeable heat. One more thing as someone who used to  modify gear  .this unit comes with only the best parts quality.transformers is a personal thing .I could have gone Lundahl on the power side also but could not hear the difference. 
Lamm audio  use Hammond on certain sections that says a lot.
All signal wire Neotech Silver Gold Alloy ultra high purity, all hook up wire Neotech 
Single crystal Copper all Teflon jackets ,even connectors Copper Gold.quality counts on every level of the build . Compare parts with sny preamp at any price levrl.Please remember Any commercially bought 
Equipment a minimum of 4x the markup just on parts, plus a 45-50% markup for dealers. 
With my build 75% goes directly into the much higher grade parts ,and you can easily hear the difference .I have been an Audiophile for over 35 years.
What I am telling you is the truth .it is up to you if you choose to  listen.
Enjoy your music !!
EAR 868PL, either of the Atma-Sphere’s, Herron (separate phono and line).
Audioman, You've posted a bald-faced advertisement for something you apparently build and sell. That may be against forum rules, but do you have a website? That fact that Lamm use Hammond transformers does not per se raise the prestige of Hammond transformers, in my eyes, but Hammond products (tranformers and inductors) are certainly decent quality.  There's better, and there's worse,
If you are interested in a David Berning preamp I would suggest give the Micro ZOTL2 a try. I purchased it as a headphone amp and its the best headphone amp that I've heard. I knew it was made to use as a pre and can power high effiency speakers as an amp. I tried it as a preamp just for kicks and was shocked how good it was. It left no sonic charicter at all. No phono however. It's built and sold by urban audio and David Berning licensed the tech to them. Don't let the small price fool you. This little thing is a beast.
The MicroZOTL2 is actually made by Linear Tube Audio. Urban Hifi is our retail store, which has a soon-to-be opening location in Takoma Park, just across the Maryland line in the DC metro area. They are separate companies, though, and Linear Tube Audio sells its products through dealers, and Urban Hifi carries more than just LTA stuff. Several reviews of the MicroZOTL2 as a preamp are linked on our website, lineartubeaudio.com

I don't mean to be advertising, just clarifying. Knowing quite well what goes into a David Berning product versus a Linear Tube Audio product, I think the Berning preamp will be step above the MicroZOTL2, though I have only heard the MicroZOTL2.  
I am using the Micro ZOTL as a preamp as of yesterday and I am very impressed. If your looking for any type of tube coloration you might as well look elsewhere. It is the most transparent pre I've ever heard. Still breaking in so more to come.
