Absolute top tier DAC for standard res Redbook CD

Bill,
I raised that issue earlier in this thread as well, the notion of extraordinarily long break in is puzzling. What choice of a part, material, construction techniques etc is responsible for this? I accept the general premise of necessary break in. It would seem that transformers, capacitors, wiring and other parts should be reasonably seasoned after 200-300 hours (that's quite a long period). Could someone explain the underlying reason for extreme break in periods? What in the world is taking place during all those hours?
Charles,

My amp seemed to continue to sound better up to 1.5yrs from new. I used it about 15hrs a week. I am not sure why but here is a theory. The better amps eventually align all the molecules and atoms and other things all the way back to the power plant and out to the speakers. Thus creating a more coherent non nasty flow of atoms and molecules and stuff. Why else would it take so long? Yea that is it.

Perhaps it is just me Grannyring... But most pieces I had had in my system took that long, or even more... Esoteric X-01 and K-01 for example, both about 1200 hours... And my Vienna Die Muzuik speakers took 1500 hours... Even my old
ARC Ref3 took about 1K hours to fully bloom. I remember evaluating a very expensive twin-box player once upon a time... I did throw in the towel when I reached the 2K hours mark and realized that the device had stabilized, with no musicality to show for the effort.

I fully admit that I am excruciatingly patient when evaluating a component... If in the end I really like a device, I then use it for several years... So, even 1500 hours, becomes a perfectly reasonable investment of my time, when I consider it against the long run enjoyment.

I suspect I do not even know how to spell cwik gruddiphicationn *grins!*

Hi again Grannyring, When I break in a component, the device is exercised 24/7 until it stabilizes... For Aeris, I fed a signal into it, such as a break-in CD, and let the DAC feed into the Criterion preamp on 0 volume.... In one week I had 168 hours already... The 1K hours mark was just shy of 5 more weeks away, and after one more week I was close to 1.2K hours... I sampled results every few days. G.

Long break-ins are usually a result of a LOT of plastic dielectrics in the design; capacitors, cabling and circuit boards. IME, its better to use non-plastic dielectrics like ceramic, paper-in-oil and cotton. These require virtually no break-in and actually sound better than the plastics, even when the plastics are fully broken-in.

This is why I really like Jensencapacitors.com air-core inductors, ceramic caps and the Duelund caps. Great for speaker crossovers, actually the best on the planet.
