- #234 guruboolez: We can either use 3.98 alpha or ask John33 to compile 3.97 beta in debug mode
- #256 guruboolez: --athaa-sensitivity benefit was discovered long time before I knew and used it. Ask Dev0 or [proxima]. I don't think that Corelli and Bruckner are their favorite composers.
- #263 Gabriel: Regarding the --athaa-sensitivity switch, I know this would improve quality with high dynamic tracks. ... I would consider this to be cheating.
- #266 Dibrom: I agree with this part. ...
- #290 sTisTi: As regards --athaa-sensitivity 1 (a1) with LAME, wouldn't it be the most pragmatical solution to ... If LAME is to be tested at its full potential, it definitely has to be included IMHO.
- #291 Gabriel: Right now, this switch IS NOT AVAILABLE with 3.97b.
- #292 skelly831: Is it available in 3.98a2?
- #293 Gabriel: Yes, but I would not recommend using an alpha version for a public listening test.
- #294 skelly831: Not even 3.97a12?
- #295 guruboolez: sTisTi> you just expressed my innermost thoughts
  Even if --athaa-sensitivity 1 is not the right answer to current quality issues audible with -V5 preset, it's at least a temporary fix, which works pretty well, and which is available for the end users by using 3.98 alpha - available on rarewares.
