Amps with meters ...

I have an ARC GS150 with meters. But they are linear and don't move at all at lower levels. They should be log meters, like what Mac uses. But the printed scales on the meters are log. I told ARC about their error but they ignored my comment

Or consider amps with incomprehensible meters.
The Marantz SM-11S1 has an enigmatic porthole, front and center in the faceplate that contains a digital numerical read-out that constantly varies in values and, for the life of me, I can never fathom what it is that Marantz expects people to get out of this tech for tech's sake.  Useful information is the last thing it provides.
OTOH, I totally love all other aspects of this amp, especially the sound quality and bullet-proofness of build & operation.  

Gregj, perhaps your letter wasn't threatening enough.

Anodyne, you need to enjoy the incomprehensible and enigmatic, not question it. Mr Squires certainly doesn't and look at how many of us have responded to his thread.

It doesn't matter either way. I think amps with meters look no different than a receiver. Just lights. If you find that distracting to your listening experience, then you have other problems! 

If you really want Meters. Here you go. Many pre amps have two outputs
