I would say it was worth it.Had it installed in a pre and power amp.I cant really separate the sound out even though on an upgrade in 01 on a 20 I had done without it,to one done in 05 on a 100 with it, as I didnt have the 2 amps at the same time in the system to compare the difference.You know how elusive time is Peter,good to hear from you,Bob
