vincent sv226 MKii or vs236 mkii

I can get the 226 for about 1100$ (yes, these are the prices for used equipment here) and the 236 for about 1600$. That's a huge difference.
Does the 236 is so much better than the 226?

My speakers are a pair of von schveikert vr2.
I owned the 226MKii. Thought it was a great sounding integrated. More to the warm side than cool and analitical. Never heard the 236. Not familar with your speakers, how difficult are they to drive? What are you using for amplification now?
