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.)
Would you know if there would be any differences in the image performance between the two vaddis chips when converted to sdi out ?
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.
