come on then SN techy types hopefully you can settle a heated disscusion at the clinic today!

I was under the impression that a digital coaxial lead is a better way of hooking up a dvd player to the amp due to the optical signal having to be converted back from light into a digital signal thus loosing quality over a coaxial lead?

or am I just talking out my a**e?


hope you can help.

In theory, the more conversions that interfere with the original source the worst it will sound. Questions are a) can you tell the difference b) do you care

You'll get Audiophiles over on avforums.com arguing for and against both till the cows come home.

P.S. I've been told coax is better, but given the same quality of cable I can't tell the difference.

I'd go with coax. The same signal that is sent directly down the coax has to be converted to light pulses for transmission down a fibre-optic and then converted back in the amp. Why bother

audio or video ?

I use coax for the video feed and fibre for the sound ...

audio please


do they do optical/coaxial video?

I was under the impression that digital video output was currently only via DVI or HDMI to a suitably equipped HD screen. I may be wrong though.

Hi Adam,

May be it would help if you advised what DVD player you're trying to hook up to what Amp! I've had a Toshiba connected via Coax and I'm now runing a Panasonic via optical fibre both to a Sony Amp. I can't say I can tell the difference. However as stated earlier try asking on http://www.avforums.com/

Isn't a Home Theatre Set-up a little over the top for the New ScoobyClinic Waiting Room? I'll look forward to a demo of it on Thurs!

Cheers,

Ian

The coax output is classed as SPDIF (Sony Philips Digital InterFace).

One could argue that the Coax is sheilded however, it only really comes into its own over longer distances, thus reducing exterior interference.
However, it is prone to signal loss due to resistance inherent in the cable.

Optical/lightpipe purely dependant on the quality of the reflective surface inside the cable. Obviously, with poor quality/blemishes, the light signal will degrade too......

You pays your money, you takes your choice......


or something like that!!

but to answer your question, once in the amp, it pretty much has to go through the same D/A converter.....
