Your monitors should be fine for this part of learning curve. Take some of your favorite music, play it through your speakers. Does it sound like you think it should? If it does you're fine. I have no experience with the HS5's but never had trouble getting good sounds out of 5" speakers.You think so? I just bought them recently
A 5" speaker won't have the bass of a larger one, but for now that isn't really important. You should be able build tones that sound very similar to what you find coming out of those very same speakers when you play recorded music through them. Once you learn how to do that you can compensate for different playback systems.
