transport suggestions for northstar dac

Dear all, please help me to find a good transport for northstar 192 dac, I know the northstar has its own transport but just hard to find now, so whatelse is good match? is it better with a transport with i2s out? Thanks
I would recommend the Northstar transport and using the i2s
From what i could read, the Northstar Transport uses the stock CDMPRo2 SPDIF and I2S out. they have given it a good power supply and robust casing.
As an alternative I have found Softone to be a very good CDM Pro2 based transport at less than 1/2 the cost..only problem is shipping is from japan. it only has RCA SPDIF out..if you speak to him he might customize an I2S out as well..
