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.

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.
