I also have an EAD Signature pre/pro. Get a transport that has Glass ST fiber output from Wadia or Levinson. The Spectral, Sonic Frontiers T3, Krell KPS 20T and Wadia 270 are excellent CD transport but they work better with their own DAC's to take advantage of seperate clock and data lines feature which is not available on the EAD. The SFT1, PS Audio and Theat Basic are also very good transport but replacement transport is very hard to find since Philips stopped making it a few years ago. I have a Wadia 850 and connect it directly to the amps via balanced outputs.
