Sorry if this question has been previously raised and answered. - I am
considering adding an HDTV front-projector to my present surround system
(speakers include front Magnepan 3.6Rs driven by a Rotel 1090, mid CC2,
rear Maggies, etc.).

For clarity, as discussed, the speakers and TV screen will be located in
or near the "front" of the room, and the front projector will be near
the "rear" of the room. To integrate my (Sony) surround SACD player and
Onkyo receiver/processor (used for SACD and Dolby 5.1 surround sound)
and a stereo pre amp and stereo/SACD/video (used for stereo audio,SACD
stereo, and video), I will need to run at least some of the
interconnects and/or speaker cables for rather extended distances. For
example, if I route the video signals from the DVD player along the side
wall, over and around a door along the side of the room, and along the
rear wall to the projector for example, at least some of the cables will
extend 25 feet or so. If the surround receiver/processor remains in its
position near the front of the room near the power amps and speakers,
the component video cables to be connected to the video projector would
extend about 25 feet (around the side of the room, and half-way across
the rear of the room to the projector). This would leave the speakers
fairly close to the power amps, permitting the use of 12 or 15-feet
speaker cables to drive the front speakers.

Alternatively, several other combinations of positions of the components
could be considered. - For example, the DVD player and the surround
processor/receiver could be moved to the rear of the room near the front
projector. - This would permit the use of relatively short component
interconnects between the DVD players and the projector,and relatively
short audio interconnects between the DVD player and the projector, but
would require 25 or 30-feet speaker cables extending back to the
speakers. (or, if the power amps remain in the front of the room,
25-feet interconnects from the sudio premaps in the recevier/processor
to the power amps, positioned in the front of the room). Or, discuss
any other recommended arrangement.

Could someone who has looked into such an installation please provide
suggestions or advice. I prefer an arrangement in which the audio (in
stereo and/or surround SACD) is not compromised, but I also don't want
to mess up the video.

Thus, the underlying question is whether there would be degradation of
the audio through the use of such long interconnects, or speaker cables,
and/or, whether the video would be messed up by the use of such long
25-foot component interconnects. Also, what are the cost factors? For
example, are 25-foot component interconnects available, and what would
they cost?

I expect that others have looked into this issue, and I would appreciate
any suggestions and advice.

Thanks,

The short answer is, to the best of my knowledge, you can run 25 ft of wire
to your speakers and not compromise the sound in any way. I'm fairly certain
that the same would apply to the video cables as well.

I assume your video cable is the standard coaxial cable that cable TV
companies use and probably some RCA cable as well. If this is indeed the
case, you should not have any degradation of the video signal either.

Actually, the video component interconnects are not "standard coaxial
cable," as normally used to connect a TV tuner/receiver to cable or to
an outside antenna. Instead, they are component video (y, Pb, Pr)
interconnects as normally used to connect a DVD player to an HDTV
monitor. My question was whether an HDTV video signal can be
transmitted through such y, Pb, Pr component interconnects of that
length (25 - 30 feet) without degradation of the video signal. - Anyone
have experience in setting up such a system? Would there be a
significant price penalty?

Regarding the audio, the basic question is whether it is preferable to
use long (25-30 feet) interconnects and shorter speaker cables, or long
(25-30 feet) speaker cables and shorter (3-6 feet) interconnects. Is
there a disadvantage in either approach? I'm assuming that the gage of
the cables or interconnects would need to be appropriate for the
particular application.
