According to this https://en.wikibooks.org/wiki/Eac3to...Audio_Decoders I would need Nero, ArcSoft and SurCode at least to get the best sound quality.

That page are obsolete.

You need Nero7+plugins only to decode AAC with eac3to, and AAC don't be recoded to preserve the max quality.

But you can use ffmpeg to decode AAC, AC3, EAC3 (also 7.1), TrueHD, DTS (also DTS-HD) and don't need Nero or ArcSoft at all.

Surcode is a DTS standard (lossy) encoder not recomended at all, use AAC or even AC3 to lossy encode.
