yeah, it's not perfect but it surely helps!
i am not talking about the "amp in the room sound, which to me is lots on the feel side" when standing in front of a cab,
i am referring to recordings and how punchy and clear they are sounding (if done well of course) but just without that sterile "direct" note to them.
adding room in the cab block helps but it leads to that "cloudy" sound that cliff has described in the original post i've quoted from.
however when listening to mic'd tracks that "cloudy side effect" is just not there. i know it makes not much sense but i trust my ears very well,
though this whole thing seems like a mistery that's condemned to remain unsolved, haha.
Respectfully, if I read this correctly and you are of the belief that the IR's are the factor in this phenomenon, you are aimed in the wrong direction. Any of the IR's out in the last 6 months from CK, OH, or FAS that I have heard would not be the culprit. I cannot say more on the topic out of a requirement for tact and professional courtesy, but rest assured
it's not the IR's, or the technology surrounding them. Major label records are made all the time with IR's now, and they sound fantastic if all the other factors are well taken care of. I could, but won't for aforementioned reasons, site examples of mine that have been on Billboard #1 rock tracks and the guitars sounded crystal clear. Even prior to that, IR's from the last few years are extremely close to the live mic'd counterparts. With Nebula, you can't tell a functional difference. I've done the comparative tests. The voicing alterations and/or technology improvements in the last 6 months have, in my opinion and my own personal design have been less to compensate for a lack of realism in IR's, more that they have been to compensate for everything else in what are the commonly used signal paths and requirement of the inexperienced novice/amateur user, while still beneficial to the expert users as well. The use of these files requires, in some cases, a paradigm shift in the approach to mic'ing cabinets, as the source and destination mediums are not the same, nor are the sonic standards for commercial recordings. We're not blasting a Plexi through a Neve console to tape without a computer in sight anymore. The loudness wars, brightness wars, all in the box mixing, lack of proper budget allowance for not only gear, but professional specialists in the process flow of the amount of hands that albums used to go through, all that stuff is a factor now.
Rest assured the IR's are fine, and if this is an issue for anyone, they need to check this one off the list and look elsewhere in the wild wilderness that is 'everything else'.
Hope this helps to get pointed towards resolution, and if I interpreted this completely wrong, my apologies!
