It is hard for me to explain. I am new to home theater audio. My only experience is with using a Logitech z-5500 5.1 setup with my computer. It has been a year or so since I have even used that. This Klipsch setup is my real first HT setup and I don't have anything to compare it to, so I'll do my best.
I feel like with my current setup there isn't a lot of clarity. My receiver plays between -80ish db to over 30db I think. I have never really gone over 10db on the receiver. I feel like between -10db to 10db, there is not a big difference in loudness. There is a difference, it just isn't impressive. I was thinking that if I turned the volume up a little bit I would hear more clarity in different sounds. I'm just not impressed.
My girlfriend is an opera singer so most of what I'm using to test are some of her blu ray operas. I try to listen to pieces wih a lot of sound from the orchestra. I also tested a few of the new Star Wars movies on blu ray. Again, it sounded nice but it didn't impress me.
The only speakers that did impress me, and I hope I don't upset anyone here, were $1500 each B&W floorstanding speakers. I don't even remeber what I was listening to. It was at BestBuy a few months ago. They are the speakers with the Kevlar woofers. I felt like whatever I was listening just sounded nice, impressive, and had a real distinct and clear difference in the different sounds.
To all you experts out there, I know I sound like I dont know what I'm talking about or that I'm crazy. I actually think that I have a good ear for what sounds good, I just don't know how to articulate it.
