SACD/CD player update


i have invested on analog for a long time. From vinyl to Reel to Reel, VPI turn table to tube preamp. But sometime i looked at my shelf, there are still over hundreds of SACD and red book CD over there. also some Hi-def in my hard drive. I only have an Oppo 105 to play them. I wonder if it worth to invest on a better player. Thinking about Esoteric, but i never do  A-B comparison and don't know how much i can gain. I'd like to hear some advice. Thank you.

I really did not notice much difference at all comparing my Oppo 95 to an Esoteric SA-50 i had. At least not when you consider the huge price difference
Which is why I sold the Esoteric and still use the Oppo
OP - You might consider having your Oppo 105 modified by Modwright.  I have a Modwright Marantz 8005.  As pleasing as the stock player was, the modded unit is so open, spacious with natural dynamic swing that it frankly takes on a more analog sound.  The tubes add a "you are there" sense to the music.  You can check out the modification here: http://www.modwright.com/modifications/oppo-bdp83-and-bdp83se-mod.php
