I recently sold my Jadis JPL. It was perfectly reliable for 7 years and sounded just fine. Can anyone please comment on the Defy 7 vs. ARC tube amps? Also, a very minor point, but I found the silver and gold finish on my preamp a bit dated over time and the gold surfaces became very smudged and cloudy. Maybe there is a secret to restoring it to its like new lustre but warm water, isopropyl alcohol, a little soap etc did nothing.
