Jays Audio cdt2 mk3 burn in and user experiences

The Mk 3 is using a SC OXCO, which is to be found in off board Master Clocks.

The SC Crystal is housed in a casing referred to as the OXCO ( Oven Controlled Crystal Oscillators ). Oven Controlled being the regulator to keep the SC Crystal at a optimum Temperature.

The output frequency fluctuates from the optimal operating at 10MHz when the Ambient Temperature the Crystal is exposed to has changed. The SC Crystal is the most stable of Crystal Cuts when exposed to Temperature Fluctuation.

I would imagine, not the best way to describe what is occurring during burn in, that as the OXCO has been exposed to an extended period of consistent temperature. The advantages of this environment being in place in conjunction with other components having a period of current run through them, will become discernible as an end sound, to the recollections of the earlier periods of using the Mk 3.     

As quoted from above...

"The Mk 3 is using a SC OXCO, which is to be found in off board Master Clocks.

Maybe I'm misunderstanding what is being said above?  If the OXCO is Oven Controlled by the use of a regulator; shouldn't that keep the crystal at the optimum temperature?  Therefore, why would it take up to 500 hours to "burn in"

If someone were to average 3 hours of listening consistently every day; 500 hours of burn-in would take almost a 1/2 year!  That just really seems like a really long time to me.

Hence my honest question... does it really take a 1/2 year for the Jay's to "break-in" or is it possible that it takes our ears that long to acclimate to whatever the Jay's is doing to the final sound and therefore the Jay's really isn't changing that much from the get go?

Best wishes,

The whole process of burn is in concern to all of the electronics within the unit itself.  Not just the crystal oven. Burn in has been a controversial subject for many people…but I have heard improvements first hand time and time again. If a respected audio manufacturer recommends it to their customers why not give it a fair shake! You can let a transport run 24/7 to log hours for the burn in process. That will only take 3 weeks not 1/2 a year…
