Elaborate on this, if you're willing.
I recall seeing a glossy brochure from Sansui, here on AK, that showed the B2301 and the B2101. It seems they said the Alpha Xs had kept the feedforward, and the double diamond differential technology.
This site talks about the progression of the technology, a little bit. http://www.sansui.us/HistProd.htm
More power with the AU-D11 II and a different 'look' otherwise very little to separate them. IMOAnd so the 607 XR is not going to be any better than the aud 11II ?

^^^link doesn't work.
I appreciate being corrected regarding Super Feedfoward, that it's not part of the X Balanced amps.
Super Feedforward was used in several models of the AU-D series (AU-D22, AU-D33,AU-D55,AU-D77).
I don't have any opinion about Super Feedforward, haven't heard any of those amps.

I have reviewed schematics for several versions of alpha 907s and 707s, all of which are minor derivations of one another. None of them have any feedforward path in the power amplifier, and there are no feedforward components installed. As I said in one of my posts about Quadklipsch's 707X I think there would be significant difficulty in an x-balanced amplifier to measure the output distortion and then decide which half of the circuit should be corrected by injection of the inverted distortion signal.
