Other than Duke's suggestion above, another cdp usable as transport is any Teac with "vrds" mechanism (you see this marketed on the front panel of their cdps. Most of their cdps have this, no sweat).
Either use their digital out or solder the output wires from I2S point inside the teac.
A final possibility is a "good" Sony. Sony provides excellent (relatively speaking) parts availability. What the mid-level Sony cdp doesn't provide is discreet and stabilised power supple to the transport. So you can diy that, and all will be well. Sony is more "punchy". Teac typically allows for slightly more extension at either end of the scale.
