Hi guys, I hope I am posting this in the right section. Anyway, I just need you expert opinions on my Onkyo tx nr 609 receiver. I have connected this to my home theater 5:1 at the moment it was awesome. Here is my issue, when I use it for music using my phone (e.i. spotify) via RCA jack on AUX, my Onkyo seems too shy on volume power. I have to crank the volume 70% to 90% to reach the highest peak for my book shells speakers. In some of the demos I attended using the same receiver, I have noticed the volume is only at 30% to 40% and wow, sounds was up. I already did the sound set up by Onkyo but to no avail. Hope you could help me. thanks and more power guys
