DAC Upgrade

Thinking it's time to upgrade my DAC. Here's the system:

Cyrus CD/t

Belles Aria integrated amp

Fritz Carbon 7 speakers

Schiit Gungnir dac

The Schiit can be upgraded to "multibit" for $500, thus making it an "Yggdrasil Junior."

Is the additional $500 (on top of the original $899) worth it, or am I better off selling the Schiit and taking that plus $500 and going with something else?

FWIW, I like Schiit's business model and that they're a (mostly) California-based company. Also, I'd prefer to buy American wherever possible.

I'll be the first to admit that I find the technical (and marketing) jargon elusive, particularly where DACs are concerned. I listen primarily to CD's.

Appreciate the input!
