I tried the L PADS at neutral position and find that there is sibilence in the highs for CD replay.

I read somewhere before that old JBL speakers were made in the heyday of vinyl and tapes and were thus made to sound good with those sources. But with the advent of digital technology, the highs of CDs could be too much for the old JBL mid and tweeters.

Anybody has the same experience?
