""how many hours are required to break in 100% the JE LA 300 ME?"
Dear Guido,
different people - different experience. I was literally shocked then I was able to appreciate late prototype of Joule-Electra LA-300ME and the rest "opening and more and more musicality and better bass etc" was relatively small scale events - for me. With others (may be people who were familiar with LA-150 MkII - which was the winner of HP of TAS Golden Ear Award - and I know, now, for godd reasons) - about 1000 hours - so I heard.
Jim: If you can audition both Silver and Gold Elrod power cords with LA-300ME - kindly report us. I don;t have much experience with Silver power cord. Where I do have substantial experience is with all (but the most expensive) levels of David speaker cables. I feel (FEEL - did not measured...) that if Silver may be the best speaker cable in the world then Gold is out of this world and while you will recognize family resemblance - they are NOT equal.
Sorry, I know many people want to and do think "its only cable - big deal, who cares" and until you try you don;'t know.... For me its like explanation of the positives of air conditioner in warm hot climate - you got to experience it during Middle East "humsin" - wind from the desert to really comprehend and appreciate it...
Yours truly,
Simon
