If you want to see how a bunch of the new receivers only put out ~30 watts when they go into a secret 'limp mode' with no indication that you are not getting the 135wpc you paid for......
Very interesting... thank you for sharing! I literally just bought an rz30 an hour ago. So place this after the preouts and you're good to go.
I didn't quite see the rating on the audioscience link about when exactly limp mode occurs, but it seems to be when the system is 'pushed' - I'd imagine when trying to blast your socks off

If the amp puts out more than 30wpc into 4Ω, it locks into limp mode (unless unplugged for more than 10mins).
If you have old 8Ω speakers, they might never go into limp....but 8Ω speakers are pretty rare nowadays.
The odd part is that there is no indication on the unit that you are in limp mode. The receiver just keeps working at the greatly reduced wattage.

As someone pointed out approximate point is 30wpc.
In real world use, 30 is quite loud!
Unless you have very inefficient speakers & listen at higher than normal levels, you're probably not gonna come too close to that.
This supposedly issue has plagued those PAC units since 2021.
There has not been very many owners claiming they heard/had an issue in that time.
Quite the opposite, most have been happy with their units.
FYI the RZ30 doesn't offer preamp mode, so internal amps will continue to draw power.
The RZ30 is THX Select certified so you may not hear much of a difference.

Even if you forget and leave the internal amps on, the heatsink fans will never come on because they are not actually under load.
