At this level no, balanced is a design choice, and a balanced amp is not always better than a single ended one, it really just depends on amp quality more imo. At this price point balanced typically only added extra cost with little benefit
If you get a balanced amp, use it balance, but if you get a single ended amp, don’t worry about it, it’s not like you are missing out on anything only because you have a single ended amp
Usability wise balanced interconnects will be preferable if you have lots of interference or ground loops, or need to make long cable runs, but for this application I don’t think you need to worry about that (unless you know you have the issue)
