i would like to know if there are power meters on the market that are made for audio systems and have a peak hold feature.

the only one i've ever seen was sold at RS, but it missed the peaks by many dB and thus was of no use to me.

I've used a couple of these over the years in my non-ht audio racks.

The lights are garish, but that's what I was looking for to tell, from across the room, that something was still outputting audio without me having to have speakers turned up.
