Preamp w/ Single Line Input. But I have DAC and CDP

Yes, provided the CD player has digital output run it through the DAC. I f you like the sound as well as the stand alone player, problem solved. If the stand alone player sounds better then you might search out another DAC.

As you seem happy with your system as is, i would not be inclined to advise replacing your pre when wishing to just add additional digital sources. What source (s) are you going to use with the DAC?

Thank you all for your responses.

My CDP is a Shanling CD-T1000 SE which has a coaxial output. The Cambridge Audio DAC has S/P DIF Coaxial input and outputs. So far the only source I've fed into the DAC is Internet radio using a Macbook and Amarra. The sound is quite acceptable, IMO.

If I connect the CDP to the DAC using the coaxial output on the CDP, and then connect the DAC to the preamp line stage using conventional ICs will both the CDP and computer play through the line stage? If this would work all I'd need is a proper coax cable. I just got the DAC and it came with no cables otherwise I would have tried this already

I've had the LUMI preamp for many years and it was significantly upgraded by Scott Frankland a few years ago. Scott took it as far as he could. It's a lovely piece and I have no desire to replace it! :)

Thanks again.

Well, since I don't have a coaxial audio cable (yet) after researching further, I tried a conventional IC from the CDP coaxial output to the DAC coaxial input, and bingo, my problem is solved. SUCCESS!

I left the DAC connected to the preamp line inputs using analog ICs and can change the source from CDP to laptop by simply pressing a button on the DAC.

I had no idea it was this simple. This old dog is learning a few new tricks. Whoo-Hooo! All I need now is a proper coaxial audio cable. I can also start experimenting with the various filters on the DAC and different IC's from the DAC to the preamp.

Happy New Year.

Glad to hear you have solved your problem and enjoy the result.

Thank you, Mesch.
Today I did encounter a problem. When I plugged a coaxial IC into the CDP and then into either of the two digital inputs on the DAC, the DAC did not "see" nor play the CD. The USB connection is still fine and I can listen to Internet music through my laptop.

What seems odd to me is that everything was working OK before using a regular IC from the CDP except the signal would drop periodically. I just purchased a coaxial and figured that would solve the problem, but now, no matter what cable I use from the CDP to the DAC there is no signal.
