Yeah @Tee…I tend to agree, you are butting the edges… I have tried the Marvel RIC’s 90’s for 2 years, with 105db receivers & custom moulds, I kept on blowing receivers, they where wonderful aids to wear, extremely comfortable… But IMO, nothing sounds quite as good as a well fitted BTE, in comparison to a RIC, it is clearer, crisper and a much more fuller sounding aid, so I went back to BTE, first the Naida Paradise 90 UP BTE, for around 30 months, they are excellent, I then moved on to the Naida Lumity 90 UP BTE’s, a big step up in overall clarity, especially in conjunction with twin walled/double walled tubing, that will give you perhaps another 5db of gain, I use NAL NL2 fitting formula, I just find it gives me better results over other fitting formulas… Good luck in finding a better hearing solution… Cheers Kev
