That amplifier is unhappy.I can hear it. It can't understand why you are not playibg EL&P or Fragile by YES through it. aJazz is way cool. Joshua Redmobd man myself.But I reserve him for the Audio Reasearch Sp-3 and D-76. Make this old amplifier happy in the twilight of its technological life. Play Buddy Miles "A Message to the People" and see how happily it pleases you.Especialy Keep me Wondering" & Midnite Rider.You will be pleased and i will be Pleased to broaden your musical horizon. Once upon a time, vinyl was exemplary in its ability. Get the album and have fun. Most of all it should b fun!!!
