The Shuguangs are definitely warmer than the EHs, but be careful what you wish for...they might be too warm.
They were the stock tubes in my Cary SLP 98L, and they did have a certain allure: a rich midrange and almost spooky depth.
But they sounded a little "ambiguous" and kinda "glassy" overall.
I've been running Sylvania VT-231s for quite a few years; nothing else seems to sound "right" compared to them.
