    Can anyone tell me the main differences between the DV27, the DV27+ and the DV27A. Many thanks

    The DV27 is the original version of the player. It uses the Zoran Vaddis 3 processor. The DV27+ (not an official name) uses the the more recent Zoran Vaddis 5 processor. The practical implications of the newer processor are hard to quantify, but it has been suggested that CD-playback is improved a bit, and that there is also a small, but detectable, improvement to the quality of the video output, especially the interlaced output.

    The DV27A, as well as having the Vaddis 5 processor, also has extra audio outputs. It is capable of playing back DVD-Audio discs (rather well, I believe) and also can act as a stand-alone 5.1 Dolby Digital or DTS decoder, if this is useful.

    (More recent players will use the Sil504 board to produce progressive-scan video output, rather than the older Sil503 - but there is no detectable difference between the two as far as output is concerned. It's simply that the newer board uses a 0.18 micron process to make the chip rather than 0.35 micron. They are functionally identical.)

    Firmware updates continue to be developed and made available for the DV27+ and DV27A but not for the original DV27.

    008: I imagine the SDI mod will produce almost identical results from the two Vaddis chips. However, a simple google search will provide you with the spec sheets of the two chips.
