I know the following is not Tonex - its NAM - but it is comparatively instructive nonetheless in terms of aliasing
4 Graphs and 1 Audio Recording of the NAM Software and an ultra distorted saturated guitar Capture with DLC's Aliasing Test
NAM Aliasing @ -120db
NAM Aliasing @ -90db
NAM Aliasing @ -60db
NAM Aliasing @ -40db
I think its pretty fair to say that NAM is not "doing" much aliasing above the -40db below 0db level
Audio Demo of 0db -vs- -40db -vs- -144db
[ I chose -144db below 0db as I seem remember reading somewhere once that -144db was considered to be absolute silence ]
To audio-demonstrate this in a real world example, the NAM recorded guitar riff below is broken up into 5 Parts.
Each of the 5 Parts has 3 sections:-
1 => the guitar riff playing back @ 0db
2 => then the guitar riff playing back @ -40db from 0db
3 => then the guitar riff playing back @ -144db from 0db

My personal take-conclusion. I.
m.h.o, getting aliasing as low as possible
is very important and that is demonstrated clearly in this NAM example.
B.t.w - the same graphs with Tonex are not as "clean". (a) there is "visually" clearly more aliasing at all db levels -
and at the same time- (b) IK/Tonex have built-in a pre-applied quite severe Low Pass Filter from 16kHz and up in what I can only assume is their attempt to "mask" what would otherwise be even more obvious visual
and audible aliasing
