Nope. Not a bit. The rs1 I was comparing it to is more fatigueing. The hf2 sound more balanced. Listening to jimmy eat world, the rs1 emphasized the guitar to the point it was overwhelming the other instruments. The hf2 present all the instruments more equally. It also had a larger sound stage compared to the rs1. I'm trying them on another setup at can jam now. If you were worried the bass is lacking as in the sr125, don't be. The baseline is present.
