Any DAC better than the MF A324 Upsampler?

Hi,
I own a Musical Fidelity Upsampling DAC, I bought it a while ago to replace a EAD 7000 III It's a pretty good unit though I always thought it was something of a sideways step compared with the EAD.
So, can anyone recommend a DAC in the $1500 (used) range that would knock the spots off the A324.
Or....would anyone suggest that there is little or nothing to be gained without going to a much higher priced unit?

Your thoughts please.

Thanks
