While you can do it and the sound quality difference may be not be obvious I would not unless this is an intermediary step to get to a fully balanced system.
High sound quality sound is the sum of every optimal design, component, sub component, interconnect choice… etc. if sound quality is top of you mind, then I would not start by buying into two compromises… connecting a balanced preamp to a non balanced amp and converting balanced to unbalanced connections. While the penalty may be small… they are not optimal.
I would buy components that are completely physically compatible. Preferably that you have auditioned.
