Jed, I have not tried to recalibrate my speakers at any volumes lower than 0dB. So far the highest volume I have ever played while listening music is around -7dB and it's already pretty loud to me. However, more headroom is always good, just wonder why Outlaw and many people think the calibration with 00@75dB is the best, will this bring any benefits to sound quality?

jgubman, I forgot to mention that your explanation about no hiss from digital input makes sense to me. And thank you for the noise reduction suggestions.

soundhound, if your post we refer to was submitted in summer or fall 2002, that's maybe exactly why I could not find it. It seems that you can only retrieve the posts at this forum no further than one year.
