Group3e11,
I was on a very similar path a few years ago. I started with an NAD 7140 that I had owned for 20 years. Adding a modded Hafler DH-200 made a substantial difference, but I had a feeling the NAD was still holding me back. I tried both the Hafler 101 and Dynaco PAS3 preamps, but settled on a Wright Sound WLA12A. Adding a good tube preamp completely transformed my system. There are many fine preamps both SS and tube for under $1K, and you'll get many other recommendations, but I'd suggest you at least try tubes. You may never go back.
