My advice is to keep the Apollo (use as a transport) and get a Benchmark DAC 1 PRE or USB. I had an Apollo for about 1 year, then I upgraded to the Saturn. The Saturn was a nice improvement over the Apollo. About 3 weeks ago I purchased the DAC 1 PRE. I'm using my Saturn as a transport and I'm very pleased with the results. The Saturn by itself was a noticeable improvement over the Apollo in bass definition, midrange clarity, and space between the images. The DAC 1 PRE seems to have even more resolution and no emphasis at any frequencies. Compared to the Saturn, I think the bass is tighter and the highs are less fatiguing. Also you can buy it from Benchmark with a 30 day trial so there is little risk. FWIW, my system consists of Harbeth Super HL5, Convergent Audio Technology SL1 Ultimate Preamp, and the McIntosh MC275 power amp.
