You may have noticed that we have changed the look and feel of this latest shootout. If you have not yet read the Guide to the Progressive Scan Shootouts, then please do so before continuing. If you do not read the guide before hand, you may not understand the new system. We have also worked hard to move over the previous shootouts to the new look. You can now view all shootouts at once.
We also recommend you read the latest updates to Part 5 of the DVD Benchmark and the Chroma Upsampling Error.

Deinterlacing This player uses the FLI2200, and had performance similar to other players
with that chip. Recovery time from video to film mode was too high for us to
give full marks, and NTSC 2-2 pulldown wasn't handled, which isn't a huge issue
for the USA. This player does offer the ability to enable NTSC 2-2 pulldown, but
when enabled we saw field inversion on our test disc. They do not let you invert
the fields manually so we don’t know if that would have solved our problem.
Otherwise, it passed with flying colors. The Basics Most of the time, this player does not have the Chroma Upsampling Error.
Krell is using the same LSI MPEG decoder that is found in the Proceed PMDT and
several Sony DVD players like the 7700 and 9000. Unlike the Sony players, the
Krell does not have the chroma bug with "standard" 3-2 encoded DVDs. The problem
the Krell has is on DVDs encoded with alternating progressive flags, see image
below. You will have to look close to see it, sorry it is so small. This is a
simulation of what it looks like. It is much larger when viewed in person. You
will probably not see it on the 480p out because of the filtering in the
FLI2200, but if you feed the 480i into an external processor as we did, it will
become obvious. If the external processor is also using the FLI2200, then it
will probably masked. In this case, they switch upsampling methods every frame,
which results in a noticeable and annoying flicker. The FLI2200 will mask this
on the 480p output, but if you plug it into an external processor, it's
obnoxious. This is something that could be corrected, but would require some
work.
When casually looking at the sharpness pattern on Avia, this DVD player
provided the least amount of ringing. The Avia pattern is a severe test in this
area. This suggests that the analog anti-imaging filters used after the DACs are
exemplary. The DVD Standard is using a 54 MHz DAC and it outperformed the Denon
DVD-9000, Pioneer 47Ai, and Sony DVP-NS999ES, which are all using 108 MHz DACs.
This goes to show just how important the analog video section is. The higher
sampling DACs are supposed to make analog filtering easier, but clearly a good
job can be done with a lower-frequency DAC. (It is a form of upsampling, just
like that used for audio DACs.) The white level on the Krell was just about perfect and well within spec. The
DVD Standard also had the flattest frequency response of all players tested in
shootout 3. The DVD Standard is also capable of reproducing below black picture
information. However, not all is perfect on this player, at least not yet. While Y-Pr was
below 5ns, Y-Pb was >30ns. The Kenwood from Shootout 2 suffered from the same
problem and we believe that, like the Kenwood, this can be solved with a
firmware update. Krell has provided at least one firmware update since we first received the
player, which exposed the chroma enhancement controls in the FLI2220. Since the
chroma enhancement features are controversial (we prefer them set low or off),
this update was in our opinion a good thing. There is a menu option called animation mode. We believe this is supposed to
toggle the cross-color suppression (CCS) feature off and on, but currently it
does not do anything. The CCS is set to on at the moment. With it in this
position you will see flickering on some saturated reds like those found in Toy
Story. Pixel cropping on this player is severe. 13 samples are cropped from the left
side of the image, which we think is well beyond any standard of reasonableness.
Aside from the fact that picture information is being lost unnecessarily, the
fact that it's all from one side shifts the image noticeably. Next to the WMC PC, this had the fastest layer change of any DVD player we
have seen. It even nudged out the Denon and Meridian in terms of speed. We
estimate it takes around .1 seconds under the worst case scenario. We gave the DVD Standard a 4.5 in response time. It would have received a 5,
but we felt the next-chapter skip was not as fast as the Denon or Meridian. This is overall a generally good player, verging on excellent. The pixel
cropping is disappointing, and we hope that a future update will provide a
working animation mode, a fix for the chroma upsampling on alternating flag
material, and a fix for the Y-Pb delay problem. In a player at this price point,
we think it's only reasonable to expect these details to be done right.

Deinterlacing The Krell Showcase DVD player uses the Faroudja FLI 2200 deinterlacing chip. This is the same chip its big brother used but lacks the 2210 enhancement. I was a bit surprised by this since I thought they would have used the newer FLI2310. This player has an optional HDMI output, but the unit I tested lacked this feature. When I peeked under the hood I noticed that the HDMI ouput circuit had nothing going to it at all which means that this upgrade is most likely a hardware change. This could mean a different solution in that configuration. The Basics The Showcase features that spectacular Krell build quality typical of the Showcase line. The player has an elegant look and an exceptional analog section reminiscent of the DVD Standard. The transport is based on the earlier Phillips model, similar to the Phillip’s Q-50. It has a few of the same drawbacks as well. One very noticeable attribute is the alignment of the subpicture is off. This causes menus and test patterns to take on a doubled look. This makes using test patterns very difficult when adjusting sharpness and other fine detail adjustments. The main offender is the chapter skips, which are very slow, resulting in an almost 3 second delay per command. This made navigating through Video Essentials test patterns brutal. Its menu navigation is quite streamlined though and doesn’t have any annoying lag. The chapter skips and layer change also produce a very audible click from the player that reminded me of a relay switching. The transport is also quite noisy. For some reason the player would not pass below black information. It has a black level adjustment for digital level (0 and 16) in the user setup, but nothing for below black. Most of the user settings in the setup were enhancements including some limited Faroudja settings (Gamma, DCDi, chroma delay), but others were a bit sketchy with names that didn’t relate to any real world applications. The player also had a 7ns chroma delay in both the red and blue channels that wasn’t fixable using the player’s chroma delay adjustments. There was a noticeable flicker from 3-2 chroma material such as Monster’s Inc. This could mean two things, either the CCS is in a constant ON position, or the player indeed has the 3-2 CUE problem, either way you essentially see the same result so we didn’t pass it on that test. Given the price point of the player, I was hoping for a bit more refinement. The user interface could use a good bit of tweaking.
