I haven't really stumbled across many discussions about feeding the SR71B a balanced input signal during my extensive research in putting together a high-end portable LCD2 rig. So, I present you, the public, a couple questions, and I ask of you any information you might've come across that you can recall:
Does a balanced input signal improve the sound quality as drastically as the balanced output signal over SE?
What balanced DACs are out there other than the iBasso DB2 that is adequate?
Do you think it is worth spending the extra money on getting balanced input in your honest opinion? Why or why not?
Using an iDevice with a CLAS, I will not really be able to get high resolution files to play. Will this make a difference in your answer to the above question?
Also, one last unrelated question, or really a survey:
Do you think adding more interruptions in the signal (LCD cable with RSA plug -> RSA female to 1/8 male adapter) will noticeably affect the sound?
