Musical Fidelity Tri Vista DAC, Should I upgrade?

Hi there, I have a Musical Fidelity Tri Vista DAC that has $1000 of mods from SF stereo. It is a great unit but I cant help but think its getting a little old.

Are there any great DAC's that will smoke mine that are newer and around 1500-2000 on Agon? Oh I dont listen to Hi-Rez Audio (There isnt much yet in what I'm looking for) Just standard Redbook

Thanks a million
