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.

Matt, Stillpoints are great and tactically flexible in a variety of settings. I use Ultra 5s as turntable and speaker footers and Ultra SSs under several components lodged in a custom steel rack.  But if you ever get around to a strategic rethink of the Adona rack, also consider the Starsound Rhythm racks and platforms.  Starsound racks and platforms made a major difference with my Esoteric digital front end and Pass monoblocks.  You'd have to pry them loose from my dead hands.  
Thanks Dgarretson! I have 3 racks on my list if I ever decided to "upgrade"

Stillpoints
Grand Prix Audio
Starsound

All 3 are supposedly amazing! 
Matt, get in touch with me. Richfield found a new rack that he's going with.  Said he couldn't' believe the sound difference.  Personally, my favorite so far is the HRS rack with their platforms built in.  I've heard their gear in many high end systems and they are just amazing.  I love when you audition and they quickly take away the platform and you can hear a negative difference.  Sound floor, decay times etc...  I'm about to make a few sets of wood blocks out of cypress like Ayre and Cardas make.  I will make a nice looking set for all my gear and matching holders for my speaker cables.  


I've noticed that by lifting the cables up off the carpet is important.  It's a small, but audible difference.  I implore all of you to try it.  It's one of those inexpensive tweeks that is needed in any system that has a carpet.  I don't know if the static builds up on a wood floor where it would make a difference.  Any of you have a solid floor?  If so, do you lift your cables off the floor and if so, any difference?  
I use a Sistrum from Star Sound for my Gryphon Diablo... goodness, what a difference
