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.

UPDATE:

Merrill of Merrill Audio was kind enough to lend me his Meitner MA-1 DAC. I picked it up this morning. It is well burned in and ready for a good listen, which I will do tomorrow morning if I can.

My PS Audio DirectStream has been shipped (I guess they decided not to burn it in for me afterall, or forgot).

Merrill and his friends did an interested shootout of their own, resulting in him choosing the MA-1 as his reference DAC. That shootout can be found here:

It's a good read.
Matt, according to Meitner they have a major firmware update that will make a significant improvement in the sound of the MA-1. It is supposed to be released this month. Check with Merrill if his MA-1 has that update otherwise you might want to wait as the release should be any time now.
Merrill knew about it, and told me. It is not yet available.

Merrill is working on some new gear and had a few days to offer the MA1 to me now. I think he will need it for a while after that.

I said thank you and took the opportunity. :)
OK. But keep in mind that I have just purchased a MA-1 and if need be would be happy to loan it to you once the new firmware update has been released.

Is this the long overdue upgrade to DSD128? That should have happened more than a year ago. What is the hold up? Or did it happen alredy and I am unaware?
