Your HK3480 is a receiver that does happen to have preout/main in jumpers. You could remove the jumpers and use the Juicy Music for the preamp section and run it into the main in jacks. All of your gear would then hook up to the Juicy Music and you would would use just the amp section of the HK3480.
Juicy Music makes, (or use to make) a LINE STAGE only the Peach, a full fuction preamp, (with phono) the Blueberry and just a phono stage only the Tercel. So it depends on what model of Juicy Music you are talking about, but all of them would work one way or another with the HK 3480.
