Lossy generation in this lineage ?

I recently got a show of the Smashing Pumpkins which was known to circulate but neither on the SP hub nor on torrent sites.

From what I know it should be from the 32 kHz DAT referenced on this page :
http://www.splra.org/wiki/index.php?title=Tsp2000-01-18
It's shouldn't be the DAT-3>Flac transfer but the DAT-?>CD-R one.

However the SA and FA of my version don't look very natural.
There's no cut off at 15 kHz but something's clearly missing.

Here's a link to an extract of about 15 seconds :

And some screenshots of FA and SA.
I'm really not comfortable with it so I hope I made it the right way.

Re: Lossy generation in this lineage ?

looks like a lower quality MD (atrac) gen in the lineage
