I'm not sure it would be much of an upgrade, although I'm not familiar with the Planet. I had an Apollo R and have owned the BDP-95. While the Oppo x5 players have good DACS, I'm not crazy about their sound, they sound more "digital" than many. I've owned Oppo BDP-95, 103, 105D, HA-1, and UPD-203, so I obviously like them, but not my first choice for music. I found much better headphone amps than the HA-1 and have sold the HA-1, the 95, and the 103. The 105D and 203 are mainly for movies. I never compared the Apollo to the 95 in the same system, but my sense about the Apollo was that it had a more organic sound. The fan in the BDP-95 was never an issue for me and I had it in my bedroom, maybe 4-6 feet from my bed.
