oops!. Yesterday I had to get inspired.....I took then again LAME's Ultimate CommandLine to generate absolute tonal purity!!.
I don't think anything can "improve" this in any way....MPC is crap now!
Using LAME 3.92 (Mitiok) with a batch file:

lame.exe -V0 --preset radio -x --alt-preset insane -k -q9 -b256 -B256 --resample 48 --interch 1 -md -p --noshort --allshort --notemp --nores --strictly-enforce-ISO --nspsytune --athlower -56 --ns-bass 2 --ns-alto 12 --ns-treble 9 c:\audio\temp\filename.wav

It will apply Joint Frequency instead of Joint Stereo:
All frequencies mixed AT THE SAME TIME!!!
Bye bye to equalizers then!

Have u actually tried this out?

of course. I do not make blind posts

The file won't have any artifacts.........because the entire track will BE and artifact!!! Test it by yourself! This' only for vynil freaks, coz it sounds more pure than the CD!
If something doesn't work by any reason use Mitiok' 3.92 compile and it will work

You might have posted this as a reply to the original (joke) thread, so as to not confuse people

omg, I nearly split my eardrums open...

*lol* That was the worst encoding parameters/settings I've ever heard... Very "cool"...

CHEATER!!! *points*

IMO this' "tweaking" more than cheating....
So, if you remove the -x switch, this commandline will then make usage of WaterBubble Inc.© 's new algorithm.
Remember there are no short block, 'cos every blok is short (¿?)

What !? You made an unauthorized and inferior copy of my BubbleBath © ® generation algorithm ?

Well I must admit, your preset combination seems to have improved bubble response
There's an unique combination of bubbles, smeared ringing and noise out there..
