Is an unbalanced preamp a bad thing?

some say they hear a difference between the two and how true that is , i don’t know.

is it worth selling the preamp you have and then finding one that is balanced?    the new preamp might not have the same sound so you have to deal with that and also finding cables that sound good also.

i thought (?) the purpose of xlr was for longer runs that rca can’t do ?

i would keep what you have

odd that all of a sudden you think of this.

how does the system sound ?    if it sounds good then leave it and don’t worry about it
