Did you run a frequency sweep, with one channel active at a time? That would help you be sure if you have not. If you had a separate pre out, and could borrow an amp from a friend or buy some...

Never had issues, but some people will push their systems hard

I can share one thing I ran into

I always figured, a small amount of distortion may not be noticeable, but reference level sounds might require quite a bit of power. But consider you can drop volume setting by 3 dB, a small drop in...

I never noticed a significant difference when adding a power amp to my setup. Outlaw 7125 does 190 watts into 4 ohms at a good price, around $1000. It's occasional sale price is a real steal, IMO....

In response to last post -

I admit I was not sure how Klipsch and Polk manage their high sensitivity numbers. Of course, you are right, they could measure it a lot of ways. As I am not a speaker...

The consumer electronics industry sort of dropped the ball on HDCP2.2/HDMI 1.4 not being in lock step IMO

It's bound to lead to some customer pain, but hard to tell how much.

Thing about CV speakers is the sensitivity

107 dB! And I believe that's ballpark accurate

That means, with ONE watt, you get 107 dB at one meter. That is stupid loud. You could drive these...

The main thing, IMO, to know about power is the law of diminishing returns. If 100 watts of power gives you 90 dB SPL ( sound pressure) then 200 gives you 93 dB, a small gain in SPL for a doubling...

If 4k is not an issue, than it might come down to...
