Audio interface inquiry

Hello everyone,

I have an Imac with El Capitan and Logic: would any one have any ideas regarding best audio interface, I had a Focusrite 2i4 which I sent back due to some noise present in recordings via the award winning mic pre amps also present I the headphone which I could n't get rid of, I would like an audio interface of similar spec; 1 or 2 mic pre amps of pristine quality, balanced ins and outs, minimal latency. Any advice would be appreciated.

Thanks
