I wanted to try some encoding with the most recent Vorbis tuning, and the first sample I encoded (q8) and attempted to ABX was not difficult. There seems to be a very slight volume difference between the original and the encoded. I used the Aotuv 4.51 A64 compile to encode the file and Foobar2000's ABX feature to compare.
I will post the sample shortly.
Full Version: -q8 ABXable sample...

volume change easiest to notice around 7 seconds.

is anyone able to ABX the file?
Could not abx. Tried with Foobar ABX. Noticed clip is really clipped. -9.01 in replaygain.

The sample is heavily compressed - not clipped, AFAIK.

can't ABX it
Damn, it is pretty hard to ABX... The volume change is very, very slight, and I got fatigued vary easily... 
I'm still pretty sure I hear a difference though.
