Yeah, thanks for the nod Dougie but I think I've got all the 166 ones (I think!), I'm just looking for the one on the 159 that turns the Bose into the Becker DSP from the 166 !!
Failing that turning the 'graphic' and 'loudness' back on would be nice, although I guess I might have to resort to the 'Booster In' pin on the back of the multipin if I'm going to manage that.
Is it just me, or are Bose incredibly arrogant about telling us whats best, when they don't know personal taste, type of music, dynamic range, noise conditions and quite frankly quality of original recording etc. Alfa got it so right with premium dsp audio with Becker and so incredibly wrong with Bose. Why did they ever change ? Grrrr.
