thx for the info maybe you could educate me , btw I am using the Pioneer 578a-s
>>all-in-one digital connections such as ilink/Firewire...<<< What exactly is this ilink and firewire? what does it do?
When a player can pass a digital signal to the receiver, the receiver can do all the decoding/processing of the signal -- the player becomes little more than a 'transport' for the audio part of the signal. If you have your player hooked up using an optical or coaxial digital connection, for playback of CDs and movie sountracks, this is what it's doing. The usual optical/coax digital cable can't pass SACD or DVD-A audio, however -- that's why those players offer 6-channel analog output and their own level/bass amanagement/ delay settings. For hi-rez sources, most players are transports AND decoders/processors. (It's like in the 'old days' of a few years ago, when A/V receivers were sold as 'surround ready', and you had to do Dolby Digital or DTS decoding in the player, and send it out over analog cables to the AVR).
ilink/Firewire/IEEE1394 are different names for the same thing: another means of passing digital information over a single cable. In particular, it can pass 'high-resolution' digital audio such as SACD and DVD-A, as well as the the usual CD, Dolby Digital, DTS, etc audio that 'regular' digital cables can carry. Some Pioneer, Yamaha, Denon models and a few others brands offer ilink connectivity between players and receivers. In addition to reducing the number of cables, the advantage is that the receiver can apply the *same* bass management , channel level, and delay settings to *all* kinds of input. This standardization is nice given that modern receivers can do things like room calibration too. It also keeps the signal in the digital domain during all processing, rather than putting it through multiple rounds of D/A conversion , which has theoretical benefits.
HDMI connectiors are another up and coming alternative to standard optical/coax digital. HDMI goes ilink one better by offering *video* signal transfer too. However, with respec tto hi-rez audio, AFAIK HDMI is currently available only for DVD-A , but not SACD, transmission. I think it' s been approved, but no players yet incorporate that feature.
