    Was wondering if I could get help in maybe what might be a stupid question. I am experienced only in the yesteryear stereo stuff.

    Have an Onkyo TX-SR700 receiver and want to hook up my DVD and VHS to the receiver.

    Which is the better to use for hooking up my DVD to the receiver? Coaxial or optical ?

    Do I still need to hook up all the RCA connections for the 5:1 thing?

    To be honest, I am confused with all the multiple ways of hooking this thing up in the instruction manual.

    I just want to hook up my DVD and VCR to the receiver and nothing else. I have all the speakers and sub and ready to go, but am confused to the hook-up.

    Any help will definitely be greatly appreciated !!!

    You don't have to hook up the analog multichannel 5.1 for dvd if you use digital unless you also use SACD and DVD-A. The FAQ has your answers about coax vs optical, short answer no difference. Whatever is more convenient.

    A big hats off to the lot of you and a gracious handshake !!

    My DVD player has 6 of the RCA type connectors.

    Has a coaxial type connector next to an opitical connector.

    (and of course the typical 2 stero RCA connections)

    Thanks again !!

    "And you shouldn't need to get a special coaxial cable. Any RCA cable will do."

    Not so, according to spec anyway. An rca video cable would work. Coax digital cables should be 75 ohm.

    if you decided to go with coaxial you would have to purchase a coaxial cable itself. any RCA cable will not do because the cable is different. only the connector on the end of the cable is the same(my pc has coax out and tried to use it with my Onkyo TXDS797 and i just got static). Just like component video cables have RCA connectors on the end of them but if you tried to use normal RCA cables instead you wouldn't get any picture on your TV.(i work at circuit city and actually had a big argument with a guy about the expensive component cables being different, he didn't believe me, then came back the next day to buy them cause his RCA's didn't work) Both cables may be 75 ohm but that is just a rating. 75 ohm refers to the distance between the actual signal path(center) and the outside edge of cable. But you will need an actual coaxial cable, RCA's won't work. but to address the difference between coaxial and optical, they both technically do the same. A lot of audiophiles like optical because it uses puslating light to transfer the signal and light cannot be distrupted or degraded by eletrical interference. You can get a degraded signal technically with coaxial because of the interference that can occur with having lots of electronics plugged in close to each other. (read the link above from Neil and it is explained) I currently have my sony dvd hooked up with coaxial, but i am switching to optical because i upgraded to some really nice Infinity speakers, but whether or not there is a big difference in sound quality will more depend on your equipment. if it's nothng too special, you won't notice it and it won't matter which you buy. But there is a reason optical cables generally cost more than coaxial, they technically are better. But then again everyone's ear is differnt, some notice the difference and some don't.

    I have learned a lot and am very grateful for the input. I am continuing to do more and more reading and am very excited about putting this thing all together.

    Thanks to Neil and Brian for taking the time to shed light on the subject !!

    As far as using any old cable for the coaxial interconnect, personally, I have seen audio dropouts result from using a cheap cable that disappeared altogether after changing the interconnect. Just an FYI.

    Some misinformation here!!

    TO CLARIFY

    Any cable with RCA connectors rated as a 75 Ohm AV cable will work for video, digital audio or analog audio.

    For component video, distance can be a critical issue, especially when you get past 25 feet or 10 meters.

    My recommendation is to buy 75 Ohm AV cables for all interconnects, that way ensuring you don't have a problem.

    By the way, standard audio RCA interconnects are usually rated at 50 Ohms and thus not suitable for video or digital audio.

    If it makes any difference, I just replaced my fiber optic cable with a coax about 3 weeks ago. I couldn't tell any difference in sound but a cheaper optical is about $20-$25. My coax from www.heartlandcables.com was $15 and the build quality is excellent!

    John Garcia: audiophiles aren't necessarily the people who only like analog sound. Those are refered to as audio "purists".

    I will have to say I had no idea the thread would become so involved. I have to thank everyone for their input, advice, and comments.

    However, in reality, I am a little disappointed that we have such negative opinions on where someone shops. You a nobody if you buy from "Circut City".

    I paid less than $600.00 for an Onkyo TX-SR700 at Circut City. I would like to think that is a pretty good deal for a middle of the line receiver. I did quite a bit of research and just about everywhere, the price is higher.

    Thanks to everyone who help shed some light on this subject, I am more informed, more educated, and definitely feel I am ready to assemble this week-end.

    Thanks again to everyone !!

    I was not trying to give Circuit City a bad rap, but they are not in the realm of what I consider "high end" equipment, and certainly (by my definition) "audiophile" and Circuit City are not mentioned in the same sentence. I shop there occasionally for deals/specials, but in general, they do not carry any speakers that I am interested in. Some receviers and DVD players, new release DVDs and CDs, possibly a home phone, but not much else.

    Everything is relative. An audiophile to me is someone who will spend $4000-5000+ on one pair of speakers. A "purist" is someone who spends $2000 on a cartridge for their turntable.

    I am not a "purist", but I guarantee you that good DACs with good analog interconnects will sound better than digital every time. Except for my DVD transport, all my connections are analog. So SACD and DVD-A are for "purists"? These formats are both analog only.

    sorry for going off topic.

    WOW Somebody just got flamed!!:b You guys should not be so rough on the poor guy hes trying. I have been pulling wires for ten years since HT was only at my house.[​IMG] We need be incouraging him not flaming him. Now with that said. Maybe Radioshack would be better suited for now and leave circuit city too the 2nd year people. [​IMG] J/K
