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


My preamp is a vintage MFA LUMI preamp which has a single line input. I've been using that connection for my CDP. However, I just got a Cambridge Audio DAC and it works great using the preamp line stage but I first have to remove the CDP interconnect cables.

What is the most elegant (simple) way for me to have two line inputs so I don't have to keep unplugging IC's?

If it's not apparent by the nature of my question, I am a complete newbie to digital audio.

Thanks in advance.

Al:Thank you, sir.
The DB Systems DBP-2JAU/5 is exactly the type of device I was wondering about.
Since I'm so new to digital audio, I'm finding that fine-tuning my setup and clarifying related details somewhat confusing.

I appreciate your help! These forums can be invaluable.

Ps
I was watching your other thread concerning this. The idea of a switchbox also occurred to me however have never used one. One thought I had was to contact Schiit audio, they make a 2 input passive pre for $50. It could be used as a switchbox by leaving the volume control fully open. Possibly Schiit could make one sans volume or the volume could be circumvented. I am getting caught up just thinking out loud here, as Al’s recommendation of the DB system switchbox would certainly solve the problem.

I, as others have stated, have to believe the DAC in your CDP is better than the Cambridge. Either way I would want to take advantage of the tube output stage it has.
An input selector that I believe is well built and won't break the bank is the Niles AXP-1.

Thank you all for the great info and suggestions.

I just determined that the digital output board in the DAC is indeed malfunctioning intermittently. No point in having it repaired. It'd be less expensive to get a basic switching box and use the DAC strictly for iTunes.

Mesch, the Schitt passive pre would be very economical. An excellent suggestion, sir.

Jedi: I just checked out that Niles. Also an excellent option, within my modest budget.

Man, I've learned a lot here about digital (iTunes/computer audio) over the past few days.
Just ordered a SYS from Schiit. It's a passive device which will enable me to switch back and forth between CDP and iTunes. I'll be good to go, in a few days. :)
