When I read the comment by Cliff, "Turns out UltraRes has been broke since Version 16.03", I thought the same thing. I also think about how much FAS touted the latest Cab Pack as amazing and claimed that those IRs were pure golden.
Mic+DI is completely unrelated to UltraRes. Mic+DI makes IRs better whether they are processed at normal, high or UltraRes resolution. The UltraRes bug effectively turned off the low-frequency enhancement portion of the processing. This is unrelated to Mic+DI capture technique which improves IR accuracy across the entire spectrum and removes any distortion caused by the amplifier.
I guess the real question is that given this should be obvious to most why did you feel the need to accuse us of marketing hype. What are your real motives here?
