At what lengths will picture quality start to suffer? I saw a chart somewhere once but of course I can't find it again! Also, where can I find good quality cables 20-25' long and at a reasonable price? Much abliged!

Geez, can't let you swing in the wind like that Paul! My general understanding is that the spec for this cable is 5 meters or about 15 feet. Even so, many users have reported being able to successfully run considerably longer lengths and this appears to be related to the resolution with lower resolutions placing considerably less demands upon the cable. I also recall seeing a vendor website that tabulated people's responses based upon their equipment but I don't remember where it is. Other reputable sources are pacific cables, ram electronics, etc.

Cheapest place I've seen for these cables is Monoprice, and they do have long ones (50 ft). Haven't tried them myself, but some people say they seem to work OK.

Belkin as also just issued this press release:

"Sep 08, 2005 10:00

Belkin's PureAV® HDMI™ Interface and DVI Digital Solutions Allow Use of Digital Cables at Longer Lengths; Cable Lengths of up to 100 Feet with Maintained Quality Within the HDMI Spec Give Custom Installers More Flexibility

INDIANAPOLIS & COMPTON, Calif. --(Business Wire)-- Sept. 8, 2005 Custom installers and home theater enthusiasts now have more flexibility and more cable length options of up to 100 feet with the PureAV by Belkin line of HDMI Interface and HDMI Interface-to-DVI Cables, Adapters, and Extenders. These digital cables meet the HDMI spec while integrating high-quality materials and construction to deliver pristine audio and video quality. These HDMI solutions will be shipping in North America in November 2005. They will also be on display at the CEDIA 2005 Show in Indianapolis, IN, September 9-11, at 1347 RCA Dome.
PureAV cables use silver-plated, 99.99% oxygen-free conductors, five layers of shielding, and precision-formulated dielectric material to ensure a sharp, detailed, vibrant picture, and accurate, crisp sound.

The HDMI interface is backward-compatible with DVI, allowing connection of HDMI-capable components and displays to equipment with DVI connections. HDMI-to-DVI is ideal for connecting digital displays, such as HDTVs, plasma displays, LCD TVs, and projectors, to digital source devices, such as DVD players/recorders, digital set-top boxes, and AV receivers. PureAV also offers adapters that convert your component's HDMI and DVI connections for all-digital, high-definition video transfer from DVI-enabled to HDMI-enabled components. -0-

Thanks guys, tho some of that is a little overly technical for me, and overly pricey too! Now, what about Toslink? How long can I run an optical cable? I need about 25'. And is it okay to use a coupler? (they only sell lengths of 12' where I am shopping).

Yes, it's ok to use a coupler but it's not the most elegant solution. A real nice place to get all kind of lengths is from lifatec.com. Don't know what the surcharge will be to Canada but you can get just about any length you want.

Thanks Chu, Lifatec looks pretty good. I'll put them on the top of my list.

Well I tried to order my cables from cablesforless.com but they don't ship to Canada anymore! Too many problems at the border they say...

So I ordered from monoprice.com their prices seem "too good to be true" (especially for 25 ft cables), and they don't look like much, but I'll give them a try. People HAVE given them good reviews, so we'll see what happens. If nothing else it'll be a hands on lesson in cable quality Posted Image

Paul, I just ordered some cables from Monoprice myself - I hope to get a handful of HDMI-DVI adapters and a 25 foot HDMI-to-DVI cable soon...

I just got my cables - the 25 foot DVI->HDMI cable works fine! I also ordered 4 DVI<->HDMI converters, and the one I tried works fine too. In your face, Monster Cable! Posted Image

Thanks for the thumbs up on the cables guys! As long as "fine" means no signal loss/degredation (sp?) then I'm happy!

By the way.... I went to a (very reputable) local cable builder in our small town, and priced out their cheapest 25 foot component cable. $1200.

www.virtualdynamics.ca

Rick Shultz is a very nice guy. He explained a lot about cables to me, and took me through his shop. He seemed to understand that his product was wayyy too much for an average guy like me. So then he went on to tell me how to build a very good quality cable at a low price which would outperform the majority of the big name cables! (Which I'm sure is fairly common knowledge among DIYers, but for a cable company president to tell me??)

Then he offered to "cook" it for me after I built it to improve its performance!

Then, as I was walking out the door, he called me back and offered to help me solder them if I wanted!

What a great guy... I guess he figured I would never be one of his customers so he might as well help me out anyway. If anybody here can afford cables like this, I say go for it, they did look very impressive.

Wow, sounds like a great guy! $1200 is a heck of a lot of money though! Posted Image

I sure hope your cables make it through - I don't know how far Barrhead is from Calgary, but maybe that is why it is taking a little longer to deliver?

After receiving my package from Monoprice, I went ahead and ordered a bunch of Toslink (6ft and 12ft) cables and a couple of digital audio coax cables from them.

Anyways, I wish you the best of luck receiving your pj and cables!

I just received my optical (Toslink) cables along with a 30 foot component video cable and a handful of regular coax digital audio cables last Friday. It sure took them long enough - they shipped on the 25th! I only tested one 6 ft Toslink cable and it works. I imagine the rest are fine as well. I'm stocking up on these cables for friends and family who may need them in the future...

It took two weeks for my cables to arrive from Monoprice. The component cables are pretty plain to look at, but they are built pretty heavy, and work just fine. The price still seems way too low.... I ordered a 33ft toslink from Lifatec a few days ago, so we'll see how long that takes to arrive. BTW, Barrhead is about 5 hrs north of Calgary, and I don't imagine that would cause more than a day or so more shipping time...
