The tube configuration/transformer windings are not the same amp model to amp model, amp manufacturer to amp manufacturer. So some speakers end up on different taps than "spec sheets" would suggest because those "wrong" settings are actually the correct settings, both technically and sonically.

VAC has a nice technical paper ( Can I link a white paper Ivan?) that helps to explain to the layman why the "which tap" answer is variable and not so cut and dried.
Great info everyone, thank you. Given that Sashas are a popular speaker and newer McIntosh amps are also very common, is there a recommended starting point from Wilson? For example, B&W says to start with the McIntosh 8ohm taps for their 800 series speakers.
