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.

So Steve, is it your suggestion that one should always use the inside USB port on the mini, e.g., furthest from the edge?

Thankyou Matt for your replys, I would not post impressions on the K-01 untill you get 1200 hrs of burn-in atleast!, I really believe you should talk to some owners, this unit takes hundreds of hours for each setting to burn-in, then there is more!

As I have tried to tell you Dilberts before, 20-30,000 hours should be a mandatory burn in time to prevent the premature chopping and changing of audio OCDness....
I have heard/read 500 hours per setting.

I will burn in the 2 or 3 most frequently mentioned settings on the forums and then listen.

The ODSE finished off its month straight of digital food. I turned it and the computer off to give them a well deserved rest. I'll turn both back on Monday for a good listen Wed.

The K-01 is on day 2 of a it's 45 day'ish whirlwind tour of the digital burn in show.
Staring - holy crap, if I have to burn one more piece of kit in I'm going to blow an audiophile grade fuse in my cabeza!
With special guest - uh oh, now I need a new power cord, spdif cord and XLR interconnect for my K-01! I knew this was going to cost me more then I thought...
Featuring - obsessive compulsions
Produced by - an unyielding need to find the best performance possible no matter what it takes or costs.
Directed by - If my wife asks you, that cable was $132.78! And of course the store gave me full credit on my previous purchase with this trade/upgrade, and a killer discount as well....
And sponsored by my favorite quote: My worst fear is that I die and my wife sells all my stuff for what I told her I paid for it!!!!

As my great grandmother used to say, "Oy Vey!"
