Like Ozzy, I installed a LPS SE from oppomod into my 203. (One is available for the 205.) I installed an Orange SR fuse and will be installing an Audio Magic Pulse Gen ZX soon. The LPS mod is plug and play and very easy. Perhaps the most improvement resulted from plugging the Oppo into my Shunyata Everest power conditioner.
PS I have no affiliation with oppomod but am a happy customer.
