What do you do with your A/V controls (bass, treble, individual speaker volume, etc.)? Do you calibrate with a meter and a disc and then forget about it or do you change things as you swap disc's? Many here advocate setting things once and leaving it alone. I don't. Here's why. First, I own mid-level moderate equipment. If I had higher end stuff, maybe less fiddling would be needed. Second, I live in a rather noisy area with nearby neighbors. Most of the time I have to turn the sub down, and at night, off with the crossover changed from 80 to 120. I know, I lose allot, but it keeps the phone from ringing. Also, some disc's seem to need a little adjustment like Donald Fagen's Nightfly on DVD-A. Love the thing but have to turn the treble down a bit. A little bright compared to others. On Fly Like An Eagle by Steve Miller Band (on DTS) I have to lower the rears. Too loud. I know, to some this ruins the "artists intent" but I'm more concerned about my intent. Which is to enjoy it as much as possible. After all, I paid for it . Plus, I love playing with this stuff and I can always set everything back to "calibrated" if I chose. I wrote the numbers on the cover of the A/V manual. So, am I way off base as usual or are there others here who are constantly fiddling with things?
