Hi Sean, The problem with feeding first-order program material into a third-order decoder is that the per-degree max_rE gains will be wrong. For 2D: 1, 0.707 vs. 1, 0.924 (, 0.707, 0.383) For 3D: 1, 0.577 vs. 1, 0.861 (, 0.612, 0.305)
I'll also point out that for first-order program material, listening tests show that dual-band decoding and NFC filters make a substantial difference. Still important at third-order, less so for fifth-order and above. See http://www.ai.sri.com/~heller/ for further details. We're planning a new set of HOA listening tests on CCRMA's new 56-speaker array.
