Fostex International just announced the Fostex HP-V8 on their
Facebook page.
(Click the photo above to see it a larger version.)
All they've said about it so far is:
I'm not sure what the tube complement is yet, but you can see on its front panel that there are both single-ended and balanced headphone outputs, along with a rotary switch that lets you select low- and high-gain settings for either low-impedance or high-impedance headphones.
As we find out more information, we'll share it with you, if it isn't posted here by others first.
