Interesting. I have read the PDF files and must say that most of his points och conclusions are quite surprising to me. It's not how I have interpreted other sources. I'm not questioning him, he seems to have done his homework, I'm just surprised. His views are also very strong. Do these views represent common knowledge? I'm using REWv5 too. Very comprehensive and capable software. I have a calibrated Behringer ECM8000 mic and a M-Audio Fast Track Pro mic preamp. So I have the measuring capability, but apart from not wanting to trouble my neighbors even more, I'm a bit challenged in the floor space department.
