Lampizator Atlantic?

Just a few questions if you'll indulge me.
i have been looking for a used Audio Note Dac because I love the non oversampling R2R sound. With none available for quite sometime I've switched interest to the Lampizator dacs.
1. Can anyone tell me where the Atlantic fits in the Lamp lineup quality and sound wise? Above the 4 and below the L7, above the L7 or even above the B7?
2. What difference would a rectifier tube make in the sound quality?
3. Do the lower models have the same sound signature of the upper models? 
4. Not sure if anyone has any experince with Audio Note dacs but curious if they have the same organic texture to the sound?
Thank you.

Hi jb505,
sorry no one saw this yet. I'll give it a try...
1) pricing should reflect the product order but I believe your first example is it.
2) check out the Atlantic discussion over on Audio Shark for answers to this one.
3) there is definitely a 'house sound' to Lampizator DACs. I'll leave the description of it to someone else but read reviews and search for other discussions and you may be able to glean more on this. 
4) can't help here. Didn't even know Audio Note made DACs. 

Hope that helps you some to make your decision. 

Hi Guys,

I came across the Lampizator DAC recently while looking for great DSD DACs which I think Lampizator specializes in, and then he has now made thee R2Rs DACs. Any new updates regards the Atlantic ? Is PCM playback as good as DSD ? I heard from reviews that DSD is the main thing and PCM is not as impressive.
