Which D/A converter would you choose?

I have narrowed my options down to the Peachtree Grand Pre, the Arcam D33 and the Mcintosh. The Grand uses a single 9018, the D33 uses one 24bit per channel, and the Mcintosh uses 4 per channel - Not sure exactally if there are any clear advantages. I appriciate any and all advice.

Anyone had a chance to hear these?

Last bump, any input would be greatly appreciated.
