I think my concern stems from audioholics and it seems that most denon or Marantz products which aren’t top tier, let’s just say Marantz since denon is doing better. Seems to have the internal amplifier clipping when the unit gets to 1.5 volts out.
I am guessing after your read is that the sinad will suffer but the unit will still function. Clipping is my only concern and I am not sure if he meant with the amp on or pre-amp mode
Edit: think I will do this for now, not sure if it will make a huge difference or not. I have a parasound HCA-1000 laying around and it’s input sensitivity is .775 for max output. I’ll run that on my LF and RF and put everything else on the 8300.
Not sure if I’ll run into any issues since the amps have different sensitivity
That's correct, at 1.4-1.5 V the internal amps will likely start to clip. The increased distortion would appear to be the reason for the preout SINAD to drop, quickly initially but would settle to about 70 to 75 dB at 2 to 4V, and then the preout itself would start to clip.
There should be no issues using your HCA-1000 with the 7015, both having comparable gain.
Parasound's input sensitivity spec is for 28.28 V, that is about 100 W 8 ohms. For the rated 125 W it would need about 1.1 V.
When looking at sensitivity specs you have to read the fine prints, as manufacturers may or may not specific the required preamp voltage for their power amp's rated output. Parasound's is a good example, though in this case the HCA-100 did provide the voltages for both 28.28 V and the rated 125 W. In other cases you may have to do your own calculations.
