In fact, the harmonic content of any filtered sound WILL BE DIFFERENT! And when this 'filtering' is achieved the THD of any such processing system will be affected. I frankly think 5% quoted is actually quite good. Further, I _do not_ believe it is possible for a person with severe hearing loss to experience the London Philharmonic as it is by those with normal hearing. But I do believe this is practical right now. furthermore the HA boffins are mainly focused on intelligibility - not fidelity.
