So when you plug your CDP into an external DAC, does that somehow bypass the internal dac of the CDP?

Let me ask it a different way, when you plug your CDP into an external DAC, does the CDP now become a transport?

Any difference between a dedicated CD transport and a CDP when plugged into an external DAC?

Clear as mud... right?  Thanks!

 "Clear as mud" You got that right!! I'm told that when using a CD player as a transport it does bypass all the internal thingamajiggers inside of it. In my own personal experience My CD player sounds pretty good. When I use it as a transport to my DAC things sound a wee bit better. Not like night and day but if you give it a try you'll hear what I mean. One other thing. CD player plays a bit louder than when it is hooked up to a DAC. No big deal! Just the way things were designed.

Now we are back to"Clear as mud"

Charles, "the internal thingamajiggers inside of it"... now I get it. Thanks!

  Well, yes is the answer as Charlie confirmed. However a dedicated transport has an advantage of not having all the thingamajiggers in it. Beware of thingamajiggers.

If you are going to use highly technical non-specific language like this at least get it right so you don't confuse the casual onlookers.
 It's doojiggers and thingamabobs, I thought everyone knew these basic terms.
Thingamajig is specialist term that doesn't really apply in this case. Advanced engineering descriptors include but are not limited to: whatchamacallits, dothingys,whatiss and dohickys.

Hold up, guys... all these highfoluttan words has got me real bumfuzzeled.  Never did know why they called a dac an Ack.  Please, no explanation cause I already got a headache tryin to understand those last few posts.  BTW, down here in Texas, a post is what we use to build fence. 

rollo, good point!

In Wyoming we used use posts and poles to build corrals.

Well Guys:
  I sure am glad we are all on the same page. For a long time I thought I was the only nincompoop. And that goes to show you what I don't know. Now Ain't that a BITCH!!!

My Arcam does play out of both. I ran rca to pre and digital to a dac then to pre and got sound out of both. Difference from what I understand is digital out is before all the other rigamarole.

[Wayner]

In the digital output, the data stream is directly from the reader head (for the most part) in the player, bypassing all DACs and filters used internally. This gives the user more flexibility in the data stream conversions as well as filtering schemes that are available in today's modern DACs.

I run a Sony XA20ES CD player with Van Alstine Insight+ DAC and the combination has kept the Sony from going to the land of obsolete. The transport in this deck is awesome and the ability to change out DACs keeps the deck "up with the times".

I use my Sony XA20ES CD player in a (rarely used) secondary system.  As I recall it only has optical digital output and my primary DAC doesn't have optical input.  But good to know you value it as a transport.

The digital out of a DCP makes use of the spdif transceiver which is affected by the CDP's clock/oscillator which is affected by the CDP power supply. Using TOSLINK optical spdif adds another conversion step. By using the digital output the distortions of the DA chip and analog output are avoided, but the digital signal itself still has modes of distortion that fall under jitter. Many of the newest DACs have jitter reduction or jitter elimination methods.

Hi wayner,

What about if u have a CDP that has been modified with a clock upgrade?  Will that improve it as a transport or is that bypassed as well?

 I've never heard this term before, mud. Is that some new determiner of sound quality? Are you describing bass or the overall sound?
