TRANSPORTER???


What does it do exactly? Thanks.

Actually, Jerry Ozment, the late digital designer, told me that most designers who have multiple digital inputs on their DACs will have optimized their design for one of those inputs, so while mattmiller may be correct as a general matter, it can depend on the designer as well. 

Toslink can be all right, but can be beaten by the other connectors if they are done properly.  There's also the ATT glass output, which is generally regarded as a much better fiber optic link than Toslink.  Also there's a bnc type of output which I believe is well-regarded--my old Forsell transport had that.

Widespreadpanic, as for your question on a transport vs. a CD player, the answer is generally yes in theory, as the designer can optimize the design for a transport and put the money into that design rather than having to also deal with the digital to analog circuitry and power supplies in the confines of the single box.  But there are a lot of CD players that work well as transports, and the advantage to that is that you can bypass the digital to analog circuitry in the player to get a better-performing DAC when you get the upgrade itch.

The idea of having a separate transport is to optimize and isolate each component, theoretically for better sound. The transport will take care of the mechanics, display, remote features, and retrieving the digital data from the the disc, however it needs to be converted to an analog signal before it can be amplified (preamp, integrated, etc.). Then there is the DAC (digital-analog converter). Having a separate DAC enables one to experiment with different designs and provides the proper analog source outlets to your preamp, integrated amp or receiver. In addition to the outputs that mattmiller listed above, some transports and DAC’s have AES/EBU (balanced), spdif (BNC) and AT&T optical. To complete the system you will need some type of single digital cable in the format of your choice. I think the best cable choice is AES/EBU (wire) and AT&T (optical), however this connection is rare to find.
Thanks for the help, folks. I was looking at the oppo 205 last night. This thing looks like it can deliver audio from any medium except tape and lp’s. Out of my budget but I can be patient and save for a couple more months. Any thoughts for a novice choosing this oppo?

How about the 203?

CD transport ~ LP turntable.

Many transports have the DAC in the same box=CD player, whereas very few turntables have the phono amp built in (but a few inexpensive ones do).

The phono amp is usually either stand-alone or in the pre-amp.

Same with DACs, stand-alone or in the pre-amp.

I like the two separate DAC’s, one dedicated for stereo output, of which balanced outputs are offered. To wit, I have balanced connectors and inputs on my preamp and my main audio medium will be digital. My stepfather has a vintage turntable and reel to reel that I secretly smile and wink at when I visit my parents and consider the empty space that they will fill in my system one day. Until I get to fiddle with those toys it’s my 300 disc collection and I like the looks of services like Roon.
