I've gone through a number of preamps over the past few years. I understand that you want DSD and that's great but leave that to a separate DAC and focus on your preamp and the heart of the system. All inputs run into it and it can have a tremendous effect on the overall character of the system.
Based on what you're saying you're looking for I'd try a tube based preamp, particularly one with 6SN7 tubes. Someone mentioned the LTA microzotl. That's a great unit and hot right now but there are lots of other things on the market. I have a ModWright LS100 and it's the best sounding thing I've heard in my system. I keep having upgradeitits out of habit but I don't want to upgrade it. It sounds too damn good. You can find one used in the 2500 range or from TMR for a bit more. Backert makes a nice unit that you can put 6sn7 in. You might be able to find a used Atma-Sphere MP-3 with the phono stage in it used as well. If I were to upgrade that's where I would go but I think my phono stage bests the built in one so havent pulled the trigger.
