Balanced IMO is considerably better in my system. Granted I have a long run preamp to amps. Consider this: if balanced isn’t necessarily better why do companies provide the option knowing the unit will be more costly than single ended? Just another up sell?
Common mode noise rejection is no joke. 6db quieter compounded with each component (the next component has received and pushes out an even lower noise level and so on).This can be significant. The connections are more dependable and components can be placed with more latitude.
Mentioned above as being better in my system. Having a considerable sum invested in my system, until going balanced I sensed something missing (the rabbit hole is in play here), afterward a sense of completeness. Good luck. JMO
