It's a little hypocritical of you to accuse other piece of equipment basically being a distortion devices. Phono preamps/tubes, talk about your EQ and distortion adding components!
One think you'll learn about audio engineering - whatever works, works. Don't limit yourself with pre-existing biases.
Onhwy61, as you can see above, I do already agree with you regarding all the distortion/equalisation issues you have noted.
I should mention that beyond the theoretical, I have also experimented with both graphic and parametric equalization in my system and have felt that the benefites did not outweigh the downsides whereas I have found few downsides experimenting with room treatments. At this time I should add that my listening room is also currently my studio control room. It is rented and cannot be altered; there have been some concessions made and lots of experimentation with room treatments. I do realize I don't have the WAF issues and can have bass traps and other doohickeys hanging around all over creation if I so desire. That's a benefit for me and it is what it is.
I do agree with you completely that whatever works, works. EQ has not worked for me; hence, I am making my argument here. Simone sought opinions and certainly got them! All readers of these threads should have a grain of salt handy as they are subjective responses to be taken for what they are, where they are, for the price paid.
