Hi folks,
Again, thanks for the continued expertise and help. BTW, I should mention I'm on a pretty tight budget which explains my rather dated and very modest system as well. :)
Started the experimentation this morning with room dynamics while waiting for Radio Shack to open.
I'm still testing but it seems that room dynamics is having a strong first order effect.
I changed the configuration of the room such that the listening direction is across the narrow of the rectangular room. So, the listening distance may be slightly shorter (not by much -- maybe a few feet at the most) but it allowed wider separation of the speakers. I also put up some fabric to try to minimize reflections.
This change allowed me to increase volume levels from about -20db (when I would start to hear harshness) to about -5db (where it starts to get uncomfortably loud); at this point, I hear a little harshness but it's not nearly as much as before. The harshness is almost (but not quite) acceptable.
Wow!! Just a little grunt work and things seem to be improving. Either that or I need coffee and my ears haven't woken up yet.
I'm still working my way through the 4 steps but so far things seem promising. I'm hoping to make what I have work -- basically have a zero sum budget. If I buy something, I need to sell something else. :)
BTW, a lot of terms, brands, parts (ie - HF glare, congestion, ferrite clamps, etc) you folks mention are new to me. I've been spending a lot of time looking things up on the internet. Thanks -- I'm learning a lot. This has been a good experience -- you've all been very helpful.
