Long digital or balanced cable run?

I vote for the latter. Most digital cables are not really meant to be used in lengths longer than 1.5M to ensure the validity of sampling/clocking. The balanced interface on the other hand was designed for longer runs.

See the attached link to a document that may be of help regarding the differences in signal formats/cable runs and the voltages behind the specs.

AES/SPDIF

I believe AES is digital. I was referring to balanced analog.

I do not had AES inputs and outputs.

Sorry! Reading your post it sounded to me as if you were considering implementing a longer coaxial cable from your streamer to dac OR balanced from dac to pre. Even if you’re using AES for digital the document sent will provide you with the distance limits for AES. 
Either way you’ll have more success using balanced if distance is the primary consideration.
