1. Exact Audio Copy - have not used anything else to go from cd to flac
3. Room EQ Wizard - used for speaker positioning, re-confirming the sweet spot, using the impulse plots to find reflections, would have liked to do a before/ after wrt my DIY room treatment but it is too cumbersome to remove, did a before/ after wrt DRC though. the REW fb2k plugin which was got me to this DRC thing really sadly is not too great.
have not tried out the others. 1) and 3) are stuff I would have paid for
knew about it but TFS nonetheless. Curious though, does this stuff have any appeal for the vinyl only ?
