Has any one used a Sub with a Anthem Tlp-1 Preamp for music listening? Has it made a difference? Has anyone used a sub with any other 2 channel Music Preamp? Looking to get a little better bass for my Music, 70's and 80's rock. Need a little more whack in the bass and Kick drum department. Using Anthem TLP-1 preamp, Anthem MCA2 amp and Paradigm Studio 100 speakers. Any help would be appreciated.
