They likely used 96 kHz, that won't make much different unless select the slow roll off filters (default?), in that case you may get closer to 100 dB but I doubt it would improve to 106 dB. They had volume set to 82, input is the same as yours, 0 dBFS for sure.
Again, please do the FFT using 3.5 kHz or somewhere around there, if you don't mind and obviously if possible at all...
No one else has done it, but Audioholics can be the first.
