suggestions for updating via DAC.....


Im looking to upgrade my system, and thought a DAC may be the way to go, since I still listen to a decent amount of CDs (I do have a bit of music on my iphone (although at lower resolution)). Any suggestions for a DAC at 2K or lower? Or any suggestions for bettering my system another way? I'm open to suggestions.

My system:

musical fidelity a3c amp and pre-amp.
martin logan aeon i speakers
NAD 542c cd player
music hall 7.1 turntable with clear audio virtuoso wood cartridge

THANKS!!!

Eastern Electric MiniMax DAC. With a little op-amp rolling and tube rolling, it's hard to beat. I love mine.
IMO the two DACs to beat in the sub $2000 category are Metrum Octave and Teddy Pardo DACs. The first one is more transparent and direct sounding, the other one is more smooth and analog. Do a google search on both.
It would be helpful to know what you are missing with the NAD?
A few years ago I owned the C541i and thought it was great for the $.
