I see, Alan, that you talk about the recent debate on QQ about the use or not use of the LFE channel for music.
I know that there is a trend to do so because many users expect to see something in the LFE in a 5.1 track. Despite it would be enough with 5.0 for music, when you play it in a bass managed system with subwoofer. You would not loss any low frequency that would go from the 5 satellites to to the subwoofer.
Even of you use the LFE channel for some content like the bass or kick drum, the aspect that has been debated here and there is about the bass cancellation that can occur when the LFE signal is filtered (under 120 Hz for instance) and consequently you get some delay in that signal, that can cancel some low frequencies when there is same or similar content in the other channels.
The solution would be (if not removing completely the LFE channel) to phase align the LFE content, after having filtered and delayed signal, with the rest of channels.
Just wanted to tell you about it, with curiosity on how you, or your mastering partners, deal with this LFE issue.
About your Faultiness 5.1, I have to say that I like more your main vocal mix with some spread extension, instead of to be mainly in the Central channel (a la Steven Wilson). Its true that you cannot increase directly the vocals volume, like we do with the Central Dialog speaker in films, but this way the main vocals are more warm and with greater presence sound stage, that I like more.
Thank you for sharing your work with us.
