Autoformer vs Speaker impedance Curve


Autoformers vs speakers with wild impedance curve swings (for instance; MC601 amp paired with B&W 802D3 speakers).

There’s a wealth of information about tube amp audio transformers interaction with speaker impedance, but I can’t find anything regarding Autoformer and speaker impedance/phase curve relationships. 

Can any techies enlighten me? 

Thanks!

(I tacked a similar post onto the end of a 10 year old thread but thought I might get a few more hits with a new thread.  Sorry for the redundancy)

Trust your ears....there are too many variables and competing criteria in the design to try to follow. Also, recommendations from someone who designs and builds amplifiers for a living (Atmasphere) is much more credible than someone who reads specs and just spits out what they’ve read. Name starts with a "g".
