According to SoundCloud's official statement, this 256kbps in AAC format is the same as the 320kbps in MP3 format. Therefore, you are actually enjoying SoundCloud music with the best quality! Personally, from these two questions, a reliable and ideal SoundCloud music downloader should be lightweight but multifunctional;(for example, brings SoundCloud downloader and the best 4K video downloader at the same time), and it better serves with a free option with the full features available.
