Sorry Paul - I have to comment here. Can I just point out that Phonak sound quality has always been good. I think what happened 6 years ago was that you had a spectacularly incompetent audiologist/dispenser who failed to program your hearing aids properly.
I have worn Phonak aids for over 30 years. I started with Picoforte aids in around 1993. I went private and bought Sonoforte23 daz aids in 1996 and these were amongst the first analog programmable aids with twin mic directionality. The memory of the high quality of these aids still stand out - with music being outstanding. I then was fitted with Savia, Venture, Marvel and then lately the KS10 (Paradise) models.
The only issue I had was with the Venture aids - where the dispenser made a complete hash job and the Autosense changes sounded completely wrong in terms of the selected environment.
No Phonak hearing aids I have ever worn have sounded horrible.
