Ahhhh!    I spy a purist !!!   Yup, absolutely right - no I don't mean hifi, I mean acceptably convenient.  But then I am deaf in one ear ( and my chum on whose behalf I posted the query is also deaf ditto ) so hifi doesn't mean much anyway.  And I'm the only guy in the valley to listen to his iPod in one ear only with his deaf aid stuck down his other ear cos the deaf aid makers didn't think to put an MP3 circuit into the £1700  hearing aid.  And yes, I am .......angry about that !   But many tks re the sales lead; we'll look into it.
Ciou Colin.
