Cant find much info on Art Audio Vinyl Reference Phono


I can't seem to find much info on this phono pre. I am looking to buy a phono preamp and I was offered one but not many reviews. The thing I do know about it is it uses a weird tube 6N1P? (not the common 6SN7 or 12AX7). I am currently demoing an Art Audio Vinyl One (Coincidence). Any input is appreciated.

I used to own an Art Audio Vinyl One. A good sounding phono preamp which I think is or was a K&K oem piece. 
I am the newish importer of Art Audio (in year 2).  The Vinyl One was made by K&K in the US more than 10 years ago to keep costs down.  K&K no longer has a relationship with Art Audio.  

The Vinyl Reference was discontinued when Vinyl One production went back to the UK.  This corresponded with a price increase.  You can find a review of the Vinyl Reference at The Absolute Sound.  

We have since added the Vinyl One Copper Reference (I know the name is confusing) which is our ultimate expression using silver foil caps.  Spectacular phono stage.  I currently have my show demo for sale at $4250.  

Everything I know says the Vinyl One is technically the better unit but Vinyl Reference is still excellent.  
@jimbones So you have the unit in house how do you like it?
Its pretty good. I could be a little more transparent. There are some caps I could upgrade.
OK so the vinyl one is better? It's not built very well. The reference looks better built and uses premium parts like Lundhal and Mundorf.
Fair...the K&K Vinyl One was not built quite to the same standard as the UK built Vinyl Reference. 

The circuit is better on the Vinyl One but was made using less expensive parts to hit a more appealing price point. 

The parts on the Vinyl Reference are going to be better as there was less of a focus on keeping costs down.  Even the face plate on UK based models are better quality made by Sheffield Steel which was known for extremely high quality steel production.   

Ultimately, when all production went back to the UK, Tom scrapped the Vinyl Reference and used the superior circuit with superior parts.  This is a big part of the reason the price has gone up.  

I have the Vinyl One Copper Reference and it is built like a tank.  
I would have expected the Vinyl reference to be better sonically than the One. Is that true?
OK so I bought a Vinyl Reference. It is a very fine phonostage. I need more time with it as i only got it today but it is revealing of cables and isolation devices.
Congrats Jim and that was fast let us know how it breaks in!
Well, it's a used unit but the tubes have lass than 100 hrs so there is some burn in time. I can say it is one hell of a phonostage. It is not as laid back as the Vinyl one (I like laid back) It is incredibly detailed and has great soundstage and depth. Tonally it is excellent just has a bit of emphasis in the presence region. 
OK so there is a lot to like about this unit, the only thing I dont like is it is a bit hard in the upper mid/lower treble region. Not sure if there is anything I can do about that
It may need more break-in but also what cartridge are you running into it?
