Any Experience with the BAT VK-90 Preamp?

Hello fellow audiophiles.  I am seeking opinions from anyone who has heard the new Balanced Audio Technology VK-90 preamp. I’ve been a fan of BAT gear for many years, I currently have two BAT pieces, a VK-76SE power amp and a VK-30 preamp. I’ve had this preamp for over twenty years, it’s a great piece of gear. While it continues to work flawlessly, I believe it’s time for an upgrade. Among another things, I want addition balanced inputs.

I’m looking at options from BAT and other manufactures as well. As for the BAT options, I’ve been unable to find meaningful reviews of their current generation of preamps out there. If you’ve heard them, I would love to hear your impressions. I would be particularly interested if you are familiar with the older BAT preamps and can speak to the sonic differences from both the newer transformer coupled outputs and the inclusion of the newer super tube.

Thank you in advance for your thoughts.
