Adcom 555se on a smart strip?

I'm thinking about a used Adcom 555se to power my new Ohm Walsh 4000s as recommended by John and Evan. This amp doesn't have a 12v trigger. My stereo "area" is the living room and the preamp will sit in the built-in cabinets next to the fireplace. I don't really want to put a high powered amp in the cabinet for ventilation reasons, so the basement seems like a good choice (and save space in the cabinets for more LPs). With no 12v trigger to power the amp on/off, I was thinking about having the preamp plugged into the control outlet of a smart power strip, and the amp plugged into one of the switched outlets. This will of course work for powering on, but I'm concerned about powering off. When powering off the preamp which will happen first, will it create a pop sound before the amp gets shut off? 

If this smart strip is a viable way to go in this situation, the used 555se will be a great cost savings. If not, I'll start looking at the Adcom 575se or maybe the Parasound A21+. 

Thanks guys and gals.

I haven’t herd the new Adcom.
I use to use, the older ones, I still have a "FEW".

I do own a ZPre3 and did own an A21. That was a great amp. Mine was paired with old Mac gear at the time.. Sure worked. Great MB, mids and highs. I sold the A21 and went class D Nord. More of a sideways move.
BUT it gave me monoblocks, I needed at the time.
I kept the Mac and added the Zpre3 for the remote, Dac, volume, and sub control. Just flawless!

I like Parasound. Great gear, great prices. A little techy to work on, though IF they ever need work. 12v trigger the A21 had one.

The off / on with a power strip, volume down wait a couple of seconds, and try it.. SEE if it pops.. Put it in to mute, and power down..

OP it's volume DOWN, or mute the pre amp, then turn off the power amp.

Nord Has some really nice options. Trigger is an option along with rack mount. I love the look and the rev d buffer boards They can use the 2590 PRO sparco opamp. You might want to look anyways.. I have  few of their units, NEVER a problem.. Wonderful sound and you can roll the opamps to change the sound a bit..  12 trigger, and they come with anti pop.

I like the Hypex modules.. NC500 or 1200, both are cool running, powerful and great SQ.

I had to get use to it.. but tone control, made it very easy. I don't leave home without it... :-)
