Achieving Lossless Sound

P.S. the Audyssey correction in your marantz is excellent. It also corrects for timing/distance, which to my understanding roon convolution does not.

Don’t think this is correct. If the convolution filter generated has included phase and timing correction, then Roon handles it. I believe that Acourate probably does a better job on phase/time correction than REW but is harder to use. Here’s a chain on generating a room correction convolution filter with Acourate:

Room correction with Acourate

I have tried to do room correction with REW and other tools, but the results were unsatisfactory. Several discussions with @Brian, @rovinggecko and others. Several people, here and offline, have been telling me that Acourate is by far the best tool to measure and generate the convolution, but also that it is difficult to learn and use. I finally decided to take this seriously, and both statements are correct. (@Uli_Brueggeman, the author of Acourate, was helpful.) The final result is excellent.…

HAF filters also correct for phase/timing and also can offer acoustic crosstalk reduction which IMHO is an advantage over audyssey (and room perfect, REW and Acourate).
