Here's the table top version Brian used at THE Show '07:

Here's the plate version installed in the subs:

I thought till yesterday they were the same amps except for the obvious external difference & the continuous phase control on the table top.

No!  Apparently totally different amps!  Plate is Class G, 12k input; Table top is Class AB, 20k input.

Just thought someone else might find this newsworthy.  Info was from the catalog, don't know about the website.

They sounded great at THE Show.

I'm not so sure about the differences.  I studied both pretty closely (or as closely as the spec sheets allowed) before I bought my RM30s with PBS mounted in the OXO.  Take a close look.  Both use an AB output stage, the plate amp claims class G but also claims AB outputs, so I'll assume that the class G part is the power supply.  The specs for the outboard unit say that it uses a "Patented tracking downconverter power supply increases headroom and efficiency" - sounds like a class G power supply to me.  I don't see any info on the outboard's input impedance, so I'll call that a wash. 

Nope, looks the same to me.

Your info makes more sense than mine. 

Thanks for looking into it.  It makes little sense for PE to engineer two different amps so closely related in purpose & function.

Maybe the continuously variable phase control circuit altered the input impedance.  That spec was not readily available to the tech guy.
