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.

1 speaker is downstairs, the other is still in the garage. My 14 year old helped me get one down but he had to leave for a school function. I'm hoping he can help me get the other down tonight. I should have everything set up by Saturday. Fingers crossed.
Matt, try to get MSB with the new Quad DSD USB input module. I have read the new module is better with all music, not just DSD.

The lowest bottom frequency is 45Hz (anechoic). It is like bookshelf bottom end!
Hmmm, bass response seems to be a little suboptimal for the large drivers on these JBLs. G.
Abe- the MSB has the Quad DAC.

The JBL synthesis stuff has never focused on going super low. Even their theater speakers only go down to the mid 50's. It's a design philosophy, although if you hear their higher end speakers they don't sound like their limited. They are very natural sounding....
