Well, I remember Kurtis have modify his HLD-X9 to give sharper and
more noise-free picture. Now, are there any more one can do?
I have mailed Kurtis about sending one of my HLD-X9 or even the X0 to
modify for best picture quality, but have not got any answer. So let
me know kurtis if you can help me.

What I have done with the X9's is to fine tune the alignments to get the
noise to the lowest levels possible. No tweaks to get it beyond what the
machine was designed for. As for the sharpness, I can adjust the Non "HR"
modes so they are about as sharp as "HR" mode. I prefer this as "HR" mode
also defeats the ability to adjust the 3D processing. "HR" mode is still
the sharpest picture.

It was the 97 that Kurtis was able to slightly reduce noise on, not the
X9.

i 'm still looking for an hld-x9, will consider the x0; my reference
laserdisc machine is runco ljrII. this sent my cld-99 straight to ebay, but
i have yet to a/b either of these japanese crown jewels up against the
ljrII-- at $5000, i'll stay happy with what i have, running the audio into
krell's hts, and the ac-3 via smartchord or yamaha DD-1, one from the
satellite, the other from laserdisc. for DVD, i have a theatris C3 server,
and would consider selling this for something in the $5500 price range---
mike moffat put it all into mothballs, and fewer than 500 of these were ever
produced, most for studios and production houses--- the C3 is not a consumer
product, but neither is my level of interest in high-end video. my main
archive consists of well over 3000 titles, and most laserdisc duplicates go
out at $5 a pop. request lists are welcome, my basement is PACKED!!! prices
as low as $2.99 with free shipping. the more you buy the most you save.
enjoy---:)*

Hi Kurtis!

Well, I wonder if there is MORE one can do? A better power suply in
the X9, maybe even do it 230 volt (I live in europe)? Shield of video
circuits more to get even lower noise? Or the most crazy thing I can
dream of, get the best comb filter today, take the composite signal as
soon it left the laser and in the comb filter and DVI/SDI out? I would
say that I CAN pay some sums if it's possible to get more out of the
X9 or X0. I think that the laser is as good as it gets and one cannot
get any other anyway. The things I see, from an amateur point of view
is:

*Better power, more shield off to lower noise to get in the video
signal.

*New comb filter and DVI/SDI out, so the signal does not have to do a
D/A and A/D again in my Crystalio processor. S-Video cables do have a
problem to have exactly 75 Ohm.

*Maybe some other stuff can be upgraded to better?

So what do you think Kurtis? I don't believe one can get so much more
resolution out of the X9/X0, but lower noise, little better colors, I
think one can get with better shielding inside.

So any thoughts?

The X9 already has a totally separate power supply for the digital verses
analog sections. One could consider playing with shielding by adding more
but you'd have to fit it in where it will not interfere.

Usually this comes down to the layout on the circuit boards, shielding
within the boards, distribution of Power, and quality of the boards. In
other electronics I've worked to make improvements and been successful but
you cannot achieve the quality of a better built design. The X9 was built
with the idea the DVNR would finish cleaning up the signal. The X0 and S2
were the last two single sided machine build to have low noise and a pure
picture, the CLD-97 was the best 2-sided machine. The X9 is very nice but
if you open it up you'll see it's base design is not the same as these older
units had.

I do not have the time to play with these types of things as they are very
time consuming and my kids want to play with tier Dad, that is more
important. Since HDTV's are digital you actually loose the effect of the
lower background noise as the signal gets digitized anyway.

As for the comb filter, the one in the X9 is very nice. I have not yet
found a regular TV or HDTV that can match it.

I think tweaking this unit for the best picture you can get is the biggest
improvement, otherwise for the person who wants to play more with this,
trying to make a shield to go around the video board would be the next step
and shielding the power supply would cause it to get hotter without adding
cooling.

In conclusion, when I first got my X9 I was really disappointed how the
noise levels were equal to the CLD-D704/99 family and NOT the CLD-97. I
have seen 5 different X9's and all are the same. I just about sold my X9
but was happy I kept it for my HDTV as the HDTV digitizes the signal so I
lost the smooth analog background my CLD-97 gave me. This is also why I
waited so long to get into HDTV as I'm not as happy about others with it. I
still think high end Analog is hard to beat. The LD-S2 does have a lot of
shielding inside trying for maximum low noise. The CLD-97 only really
shields the power supplies and it does fine as the initial design was
focused for low noise without DVNR.

Since laserdisc is analog video, DVI and SDI don't apply.

Thanks for your answer Kurtis. I will look into if there is any in
Japan that can and have any knowledge of doing this. I would prefer to
have the X0 modified to the best. I will look into this with Nicolas.

Thanks again

Wel, you can (i think you can) take the signal when it's still
digital, in the comb filter and send it out. I think Stacey Spears
talked about this on avs a couple og years ago.
