Break in period

No need to worry about the neighbors. The gear doesn't have to be played very loud to achieve the burn-in needed...usually around 200 hours.

I wouldn't leave tube gear unattended, but I do leave it on during the night, while I sleep when I'm breaking it in.

People who don't believe in break-in of gear are the same people who don't believe cables make any difference or that they need current to settle. They do...and it's usually around 200 hours to achieve 90%.

Speakers benefit from wide dynamic and volume swings. Everything else just needs current. The problem with tube gear is that the tubes can begin to short and if you aren't around to notice the "pops" then you could destroy your speakers or take out an amp.

maybe my next audio investment should be an hour-meter! ;-)

"My ARC Ref 3 improved dramatically from 0 to 150 hrs, significantly up to 400 hrs, and subtly up to 550 HRS;"

While I don't have a REF 3... my LS-26 is tracking quite close to the REF in terms of sonic improvement.

I left it on continuously for the first 120 hours or so... then began powering it off at night. I do agree that power cycling components helps the break in process... at least in my experience.

Many thanks for taking the time and the effort to respond.I guess I am going to do nothing special apart from savoring some good/great single malt and let the CJs gradually overwhelm me. I began a complete revamp of my system in Sept 2006 with the CJs being the latest entrant(6 days old as of today).I guess there is a multiple break in underway,since the Cardas Gold Ref speaker cables are also barely 2 weeks old.
I confess the decision to plunge for the CJ gear was not based on actual listening/comparisons given the limited availability of brands in India. It was largely prompted by perceived compatability with the rest of my gear and the desire to build an all tube/ESL system. ie MF kw 25 DAC & transport,Quad ESL 2905s speakers. In a sense the system is largely based on the July 2006 Stereophile which had great reviews of all these components.
The system looks and sounds incredible and the prospect that the sonics can only improve is enough to keep me smiling!!
Many thanks and happy listening.

The bottom line is if you like sound out of box than you don't need to worry about break-in.
