both units sell for @ $1200, as you see.
Monster AVS2000 claims it is NOT a surge protector and needs separate plug-in unit.click here
PSAudio Director claims surge suppression, but I see they dont make a big deal about this feature in their specs.
Depends where you want to go in the world of surge suppression up to the separate category of "power conditioning."
Truth-in-posting: I do not own either unit.
Here's two approaches.
Using MOV technology (unit designed to FAIL and be replaced under massive surges) there's TippLite ISOBAR12 rackmount style (1200 Joule) for $91.CLICK HERE
For longer-lasting no MOVs, there's the Brickwall PWRM15AUD ($359) and so-amp version PWRM20AUD ($379). Here
Both perfectly adequate surge protectors, also incorporating some AC line noise filters for RF/EMI.
I use a PS Audio P300 Power Plant along with a PS Audio Ultimate Outlet. This combo is killer. My system opened up quite a bit. The PD is really 12 UO's. I would try a PS Audio power product over Monster first. Go to psaudio.com and find out about a in home try out.
