Best integrated amp for work?

Howdy,

I'm looking for some advice regarding my audio setup at work. Currently I have:

-Pro-Ject turntable
-Pro-Ject Phono stage
-iPhone/iTunes in dock
-Pro-Ject Headphone amp
-Ultrasone Headphones

My issue is that I can't simply press a button to switch between my inputs. I have to unplug the cables from one and plug in the other. Lame.

So it looks like Pro-Ject has a $350 solution:

Which got me thinking that I'd like to see what kind of all-in-one solutions are out there.

Anybody have any suggestions? Ideally the phono stage is in integrated into the amp.

Thanks in advance for your advice and heckling!

Jon
