Haven't heard the Sonic Euphoria but Bent Audio has ceased production of the NOH in order to develop a fancier remote controlled TVC. He likes creating more than producing.
If you're up for some soldering, any TVC can be converted into an autoformer by wiring it backwards. I've heard some people say that it improves the sound but when I tried, it made little difference. Also, you can't convert from SE to balanced with an autoformer.
Check the DIY forums for more info. TVC's are a hot project nowadays.
