Hi,
I found some DBX units for my machine on ebay also. I just tested them and I am amazed how well they work, no tape hiss whatsoever. How did yours work. I have been using dbx for 16 years on all of my Tascam machines and I love it. Dbx seems to get critisized alot for masking the highs and for the breathng. I have plenty of highs and I do occaisionally hear the breathing only when there is a bass solo and you can hear the hiss riding along with the bass. I wonder if the people doing the critisizing are use to very high end machines that dont need noise reduction. I think it is great.
