The OP made the same very reasonable recommendation, to open and close the post, that describes his(and his relative’s) experience. The result: the typical typographical/verbal dysentery, from AudiogoN’s resident, OCD, naysayers. So tedious! My apologies to the OP, who is a fairly new member: Please persevere in your experimentation and grow a thick skin, if you intend to continue posting here. ESPECIALLY when you find something you can actually hear as an improvement in your system. There are some here, that WISH you were deaf!
