What is current best REFERENCE DVD player


I've had an Ayre D-1x for a little over 7 years now. it's been great for me. i am wondering what is now considered the best reference dvd player on the market, in terms on picture and sound quality. i would like to be able to have it modified for SDI output to, as i still use my Teranex processor. Any thoughts would be appreciated!
