Killer used integrated for

You might get close with a Zpre3 Pre and a Zpre V3. 2 channel power amp for close to the 500.00 mark.. If that is an option. Nice package, great options.. Vary compact too. As small as most integrated packages.

OP here. Wow, great suggestions. To clarify a couple issues: using the word "killer" was only meant to identify amps that perform well above their price point. I know performance will not be the same as the big rig upstairs. Second, speakers will be ProAc monitors, not quite sure which model but along the lines of the D2 or Tablette 10. 
Looks like i need to do a lot of research/shopping.

the M2si is rated at 75w/ch into 8 ohms, 135 into 4 ohms...
