Volume attenuation device between preamp and power amp

Hi all,
Thanks in advance for help with my question.

Is it safe to place a volume attenuation device between a receiver's preamp and power amp?

I am using a Pioneer SX-D7000 to power Thiel CS1 loudspeakers, and between the receiver's preamp out and power amp in I have this:

https://www.newark.com/mcm-custom-audio/50-8394/line-level-volume-control-rohs/dp/79X4195?st=50-8394

I use it by setting the receiver's volume control to as loud as I might want to go (about halfway), and then use the device to adjust the volume from zero up to that maximum. It works like a charm for the intended purpose, to add remote volume control to my vintage receiver.

But I wonder if it safe for the gear. Is it possible to inadvertently set the remote unit and the receiver's volume knob in a combination that would hurt anything? For example, one maxed and the other zeroed, or vice-versa - similar to overdriving a guitar amp? Maybe there is nothing to worry about....or maybe this whole thing is a bad idea. Let me know what y'all think.

Thanks!
Eric.

Edit/addendum/replying to my own question..........

I moved the volume controller to the Adaptor loop of my receiver, downstream from my EQ. Since the EQ (a BSR EQ-3000) has its own volume control, I figured why not put the remote control volume device in the same loop. Also, now both can be defeated with the Adaptor switch when I want a clean signal path.

Despite this addendum, I am still hoping for some replies to this thread with thoughts/suggestions on my implementation of the remote volume doohickey. I really want (need) remote volume functionality in order to enjoy my stereo.

Thanks again,
Eric.
 
I wish power amps would more often come with attenuation pots, but I guess that's another opportunity for signal degradation and cost saving. I'm also guessing that many, including me, wouldn't hear the pot's effect. It would be a nice option to offer to those, like me, who'd pay for it.
 
Thanks for the replies.
I would recommend this device to anyone who wants to add remote volume to vintage gear.
I do not notice any degradation of sound quality with this inexpensive thing in my signal path. (But, as noted above, I put it in an effects loop so it can be defeated.)
