K, but the amp's unique "reaction" to the connected cab via Xformer Freq changes is material to what the resulting speaker page curve is. I'm not arguing that somehow something "extra" appears in an amp when a cab is connected. I'm just saying that what audibly influences the curve shown on the speaker page (my bad, I should not refer to that as SIC which is an attribute of the cab only) is both amp and cab selected - not just cab. I think it's misleading to say that the "speaker page curve" is not influenced by amp selection changes only with cab remaining the same.The curve you see in the Amp block is the Amp's response to the selected SIC.
There's no "extra" component required from the amp.
The amp model + the SIC is all that's required.
