How can I use headphones with my new system?

(Yes, I am a newbie).

I got my first "entry level audiophile" system a few days ago: an Exposure 2010S integrated amp, an Exposure 2010S CD player, B&W 705 speakers, and a Magnum Dynalab MD-90 tuner. As I had hoped, they sound terrific together.

That said, I didn't notice until this morning that neither my amp or cd player has a headphone jack. (Stupid, I know). I haven't bought any headphones yet, but I do need that option.

The 2010S amp has two sets of speaker outputs ("1" and "2"), but they're intended for biwiring -- both sets are always on. One idea I had is to connect the headphones to the "2" outputs, and my speakers to the "1" outputs through a Niles SVC-1 volume control I have from an old system. I would still control volume with the amp... turning the SVC-1 volume to the max when using the speakers, and turning it all the way down when using the headphones. Work or not, that approach seems really kludgy to me. I would think that running the speakers through the SVC-1 would degrade the sound.

Another idea I had was to connect the headphones (or a small headphone preamp/amp) to the 2010S amp PRE-OUT -- but I would still need a way to mute the speakers unless the PRE-OUT is independent of the volume control. (I recall reading that it is a "passive preamp").

A third idea I had was to bypass the amp altogether... connecting the headphones (or a small headphone preamp/amp) to one of the two digital outputs (OPT and COAX)on the 2010S CD player.

What are my other alternatives? Could I use an external A/B speaker switch connected to the "1" audio outputs on my amp? Does anyone make one that doesn't degrade the signal?

Thanks in advance for any thoughts or suggestions!
