Zormi. I really wanted to like the JC-1's. The bass was definately better the second time round, but it had no life in the upper mids and top end. Just plain boring. I really think parasound need to change there caps as no one in their right mind can expect to wait 1200 hours for the amp to sound better.
The Mac 501's and Pass 350.5 sounded good after 50 hours, Krell 300cx was starting to sound better after 150 hours but still a little strident in the highs for my taste. cj after 120 hours, still improving. All these amps sounded at 95% plus at these hours, which is what high end hi fi should be like.
Interesting the low or no feedback designs ( prem 350, Pass 350.5, Sim W5) were to my ear the better sounding amps compared to their high feedback cousins like Parasound, Mac and Bryston. It was if the high feedback amps had a limiter on the expressiveness and natural tones in the upper mids/and treble. The high feedback amps had arguably the bigger bass thou. But it is top to bottom conherence and musicality that rule the day with my listening biases.
