Sorry if this is in the wrong place but couldnt find better.... Which is better to connect AV audio optical or Co-ax. Its only a short term question cause soon to get a Denon amp but my dvd has optical out & co-ax whilst the PS2 has optical out. the tv (i've no amp yet) has 1 optical and 1 co-ax. Should I get a co-ax for the DVD or just be patient (who me?) and wait for the amp and use optical for both.
