89.5 db should play loud enough with ah the power of the yamaha amp and don demand 2x100 watt to play loud or punchy
Same amp as a Yamaha R-N303 and it has enough power
It's not for me nor others in the same boat.
I regularly frequent around 3 to 4 out of 10 on the pioneer directly pictured right next to it and 48/100 on the Arcam on both occasions they are both way in excess of the Yamaha's full volume with floorstanders.
The roskan k3 is about the same at quarter.
The Yamaha goes into clipping easily especially with it's onboard Bluetooth sounding terrible which damaged a pair of speakers.
The 48mv DC offset had me look further at the amp thinking it contributed after Yamaha wouldn't share any details but it all checked out within spec.
I always prefer atleast half the volume scale in reserve (headroom) to avoid such blunders overdriving an amp creates.
You make reference to how loud a similar amp you have being loud enough for "you" in your room with your speakers.
I commented more around the time the post was created and really don't have the time to enter a debate over how loud an amp right Infront of me is.
Suffice to say I too in-line with other people's reviews dotted around, a few in particular I remember on the richer sounds website also find the amp underpowered.
