Could you elaborate?
This is where it gets more into the subjective a s opposed to the measuring of numbers that are straightforward. What follows are my opinions and impressions and should possibly be taken as the ravings of a lunatic fool!
I tried the IPR-1600 as a subwoofer amp in my dedicated 2 channel system that usually has a QSC PLX3402 driving a pair of sealed 15 inch subs which also have a Marchand Bassis being used to tune them. This is only 2 channel, not home theater so no WOTW bass stuff. Nobody could tell any difference whatsoever when the Peavey was being used vs. the QSC except when it ran out of power. Had I used one of the bigger Peavey amps, nobody would have been able to tell the difference at all between the 2 amps. My subs are crossed at 40 Hz and I am playing High Resolution (upwards of 44.1/16 KHz) music through this system. And yes, there are a lot of pieces with stunningly low bass that sound wonderful in hi res 2 channel music.
I used the amplifer for a while in my bedroom system that uses a pair of Dayton 3 way floorstanding speakers with dual 8 inch woofers, 5 1/2" mid, and Seas H1212 tweeters. Over the years I have used many different amps in the bedroom (usually cast offs from the main system) such as Onkyo receivers, Bryston 3B-ST, Hafler DH-220 modified, and currently a Harmon Kardon AV receiver. I heard a much cleaner upper mid range/high range than I have heard with any other of the mentioned units. I find it very hard to admit that the Peavey IPR-1600 sounded really good as a full range amplifier because my own built in prejudices formed over many years of using pro gear and home audio gear still tell me quite loudly that "PEAVEY IS NOT A HIGH FIDELITY AMPLIFIER". But my ears told me that I could hear more detail that was cleaner and more open than the other amplifiers. It has been quite hard to get over built in prejudices vs. what I heard.
OTOH, when I used the IPR-1600 in my system and pulled out my Pass amplifiers and inserted the Peavey, there was a difference between the two. The Pass amplifiers sounded much better in all areas. This was a comparison of a $3,000+ amplifer vs. a $300 amplifier. That being said, there was not a 10X difference between the two. Law of diminishing returns. And my class A Pass amps double as space heaters also
The amplifier sounds better than the numbers reveal, even the factory specs. If I had to criticize this amplifier, it would be external to it. GET RID OF THE BLUE LED's!!!! (marketing's fault) The thing lights up like a roadhouse in the middle of the night on a lonely southern road. Where are the binding posts? (a cost cutting measure). The fan in the amplifer is just too damn loud for the unit to sit in the same room. All of these criticisms are a moot point as soon as you use the amplifier for it intended purpose. Pro Sound Amplification. If you can work around these points, you have a damn good $300 amp that will play good high fidelity music.
