Room Treatments

Whats the best method of treating our room. Sometimes I believe we make allowances in our rooms for inadequate recording studios. Should we be trying to obtain the best sound or the exact duplicate of what we believe was recorded. The only steps I take is to insure I have the proper speaker placement and that has taken me almost a year. Im not sure Im right but I try to acheive the sound that is most pleasing to my ears. How about you.
