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.

ps
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. :)
