Sorry for the flamethrower-bait thread title, but I wanted to get people's attention. I have a couple of threads going in the HT forum about trying to integrate a HT capability into a two channel system, and there's a bit that needs to go here.
I have a Marantz DV8400 that I'm using as my source (maybe to be replaced with either a 9500 or Onkyo SP1000 soon). Now it has the DACs and DD / DTS capabilities - even decent BM - to kind of question the need for anything but a multichannel analog preamp. Here's the BUT: but if I already have a HT prepro that has only 20 bit DACs and ADCs and no MC analog bypass, do I really lose audio quality (assuming the quality of the prepro converters is better than the 8400) by running the analog of the 8400 into the prepro? If I run a DVD-A or SACD in this mode do I really "lose" something?
Sean is spot on here. Good sound from digital is mostly in how the design is implemented. I have found that transports are less important then a good dac and digital cable.
"On top of that, you now have to worry about impedance matching between the transport and the DAC. "
Sean, what is the rule of thumb for impedance matching between transport and DAC? I've never considered this. Only thought it was an issua with analog signal.....
Sean and BigKids hit the nail on the head. It's not the chips so much as the implementation. It's the board layout, the power supply, what type of parts were used etc...
