Absolute top tier DAC for standard res Redbook CD

Hi All.

Putting together a reference level system.
My Source is predominantly standard 16/44 played from a MacMini using iTunes and Amarra. Some of my music is purchased from iTunes and the rest is ripped from standard CD's.
For my tastes in music, my high def catalogues are still limited; so Redbook 16/44 will be my primary source for quite some time.

I'm not spending DCS or MSB money. But $15-20k retail is not out of the question.

Upsampling vs non-upsampling?
USB input vs SPDIF?

All opinions welcome.

And I know I need to hear them, but getting these ultra $$$ DAC's into your house for an audition ain't easy.

Looking for musical, emotional, engaging, accurate , with great dimension. Not looking for analytical and sterile.

Understand all the comments and even yours Steve. 1200 hours seems excessive and I am darn near positive any small changes are due to something else. I'll say it again, my gear changes on some days or day parts and it has nothing to do with break in. Even our electricity changes with day parts, time of year..... moisture in the air also impacts sound.

I learned that turning my past SS amps off for a short period and then turning them back on made them sound better after warm up if my amps were left on for many days or weeks at a time. I usually least SS amps on 24/7. Again, nothing to do with burn in.

After 500 or so hours we are no longer talking about burn in IMHO.

Yes, I run my gear 24/7 when new to speed up the process.

I just downloaded the new DS Firmware update. Pretty impressive with more "air". How do they do that?

Bill (Grannyring), regarding your comments about humidity being a significant variable, here is some remarkable confirmation, from this current thread:
06-17-14: Georgelofi
... this [humidity] is greatly overlooked. Take any hybrid ESL speaker for instance, they are tuned for a certain sound by the factory. The esl panel on a day when the humidity is 70%-100% can loose as much as -3db efficiency, making the balance sound bass heavy as the dynamic bass driver has not lost this -3db.

I have measured it on my new panels, dry day 5kv bias charge and on a humid day 3kv-4kv bias charge, I tend not to do any evaluations or serious listening on days when the humidity is above 70%. Or if I have to, I can with some trouble turn down the gain of the bass electronics by the appropriate amount so all is balanced again.
Best regards,

Thank you Steve. Yes, I have amps with ceramic boards, Jensen caps, and lots more esoteric goodies inside... Amazing sound from the get go... And then they kept improving.... By 1500 hours, my amps were awesome. The delightful Merrill Veritas took a little less: By 1K hours they were stable. This has been my consistent experience for the last 30 years.

Of course, Your OD DAC might very well have a very different break-in curve... Unfortunately, I have not had the opportunity of verifying its break-in pattern and its sound in my system. G.

Lets all put 2000 hours or more and fully break in our components. How about 2 to 5 years and then just maybe they will be broken in. This is crazy you get use to the sound at that point, break in still I doubt it.
