Threshold 400A Amplifier and Conrad Jonson MF2500A

I'll admit I'm a c-j fanboy, but that Threshold is a killer amp.....enjoy

Glad to hear you like it, those are butt kicking good. Looks and sound wise. I think any amp will sound at its best directly into the wall outlet and nothing breaking there communion. Reserve the filter plug ins for other sensitive electronics like your multiplayer/ cable box/ laptop and so.

I'm in a pinch for time I have a reference saved somewhere, it has lots of info and pretty pictures of past Pass designs of the era I will have to locate that one. 

No conditioner can be risky.  At least use some sort of surge protector or UPS.  I have a whole house surge protector (only trips on big hits).  Additionally, I have PS Audio & Blue Circle conditioners throughout the house.  We had lightning hit a transformer a few years back, it tripped the house surge, it totally fried one of my PS Audio pieces (Dectet), which in turn saved about $10k worth of gear plugged into it.
Would I go straight into an outlet???  Never, especially with something like a 400A which is amazing, impossible to replace and would be too expensive to repair if you do have a power surge.
