2 channel Phantom with 24bit bluray?

[mixart]

I remember with my old 2 channel setup with B&W speaker, Thule pre/amplifier connecting to PlayStation 3 with Toslink - I could get 2 channel 24bit sound from my bluray movies, because it down mixes multi channel to stereo. It was night and day different when I example switch from DTS to DTS-HD Master from PlayStation 3. Now with my 2 Phantom Gold connection to PlayStation 3 with Toslink, I can hear no different between DTS to DTS-HD Master or Dolby Digital to DolbyHD. I presume I only get 16bit sound now from my bluray movies.

I found this 4K HDR Multi-Channel Digital to Two-Channel Audio Converter:

What if I bought this, connecting my Dialog to this Converter with Toslink, my PS3 with HDMI IN - Do you think I would get 24bit stereo for bluray movies like my old system? It looks quit interesting, if it works.
