Tube Preamp

I started the discussion about replacing my Adcom 555. I would now like to move the advice to a tube preamp that has the capability to tie in my signal processor.  I'm using a Parasound Halo A21 power amp... recommended  here ... and my AR 303a speakers that I have had for years. . I would love to keep the number under $1500 if possible,

To preface I like to listen loud and boost the freqs that I like. My Adcom has been labeled not "musical"  Any help much appreciated and thanks!
