I can tell you. I list price here in the US is $26500. That isn't a typo. It's pretty crazy, imo. And Accuphase (someone from the factory) said to me that the transformers degrade the sound. You might want to ask them as well. You can buy from those Japanese equipment websites, but Accuphase told me that they are not authorized dealers. I'm not saying this is all correct info, this is what I've been told by the factory rep.
