Lol, that report was one guy is at best what I'd call a mid level amp of unknown design. In that case, personally I'd stick with the TT as a standalone. With the GS-X Mk2..the TT balanced is quite a step up with the LCD-4, HE1000, T1G2, HD800S. So like most things in life....it depends. FWIW, with my easier to drive headphones (like my Grado PS1000e or GH-1), I use the TT only.
