The analog cables you've added will now not only give you hi-resolution SACD sound but also hi-rez output from your DVD-A's, assuming you make sure it's set up that way in your player (for your DVD-A's you were previously getting a lucky 24/96 pcm thru your digital coax, cuz a few discs will do that, or more likely a low-rez Dolby or DTS 2 channel downmix).
Moreover, by "Home Theater" I assume you also mean surround speakers. For the multichannel hi-rez stuff to truly work (i.e not just hearing the lower rez DTS or Dolby dig layers from DVD-A's for instance) you will now need to additionally add analog (red and white, etc) rca cables from the universal player's center, surround and sub outputs into those same inputs on your receiver. This way you'll get high resolution analog sound from DVD-A's and SACD's in both 2 channel and 5.1. The digital coax will take care of DVD movie surround sound (DTS or Dolby) but not high resolution surround from your SACD's and DVD-A's the way they were meant to be heard.
