Could be problematic. I recommend at least 90dB. Don't get me wrong, it will sound great even on 87dB but only if you listen at a very low volume. When you put it up, the sound will "break", so to speak.
I play it together with Sonus Faber Electa Amator I which is a 8 ohm speaker with, I believe, 88 db sensitivity, and it sounds really beautiful. If you don’t want to rock really hard, you will be fine.
Can it drive floor standing speakers with 4 Ohm and 87 Db?
