Do I need an external amplifier?
I would like to understand if I need an external amp to power my front channels or my AVR is sufficient. Let me give you some parameters as context:
- listening room is a bedroom size of 17 x 12; I usually do 50:50 movies and stereo music listening
- KEF Q300 speakers with 87 dB sensitivity (supposedly 8 ohms, but i read some places may go below 4 ohms)
- a 5.1 setup with an SVS sub
- listening position is 9 feet away
- Denon AVR rated at 105W for 2 channel
- when I listen to music my Master Volume is around 50 for heavily compressed (recent) music (out of 98) and that produces about 70 dB SPL I have measured it with REW
- when I listen to music mastered in 80s and 90s my Master Volume could be around 55 for similar 70 SPL
- when I watch movies my Master Volume is anywhere around 55-60
- I have never had to turn my Denon AVR higher than Master Volume 60
With that being said,
1) Do I need an external amplifier for my front speakers to sound their best at my MLP for when I listen to music only, still leveraging the sub?
2) Would I get better sound quality (not louder, but better) from using an external amplifier?
3) Does not audio quality degrade once you have AVR pre-out --> amplifier via analog RCA connectors? The chain is no longer all digital, so I assume loss of audio quality.
