Dear Mr Shane55,
Being the intelligent person that you are, I'm very surprised you actually started this thread - shame on you! As you well know there are no reviews on the Westones, or the UEs. There's only one member with the 1964 Duals so far, a couple with the Ts and a few more with the Quads. So, right now your best bet in terms of reviews for an entry level custom is probably the JH5s. May I also remind you that apart from pianist, who goes all over HF saying that the ES3Xs are so mediocre, most, if not all ES3X owners rave about them. I've already pointed out to him he should state that he most likely got a bad fit or perhaps even a problem with the custom internals - or at least state that he is THE ONLY ONE not to find the ES3Xs a very good IEM, yet he seems not to take any notice, apart from the very odd post here or there, usually when he's been challenged.
By the same token, you'll find that the vast majority of people who own customs, from the cheaper models up to the more expensive ones, will tell you that customs are something unparallelled and that they blow their previous universals out of the water, and so on and so forth. I still maintain this is a highly exaggerated view as so many other things written on HF.
You may remember how highly I rated my UM3Xs, being perhaps 85-90% as good, SQ-wise, as my ES3Xs. Only a few days ago I got the new Westone 4, and this has now become not only the best universal IEM I've ever heard, but at the moment I cannot honestly say my $850 ES3X are even a little better, that's how highly I rate the W4s, and I've spent quite a few hours with them. I know you already have ear impressions and are pretty much on the path to customs, but I thought I'd let you know about my latest discovery. I only wish the W4 came with detachable cables at this price range, but the cable on the 4s has been improved over other Westone universals. Also, ergonomically, they are as comfortable as my UM3Xs, though the housing and nozzle are a little different, though not exactly like the W3s I owned a couple of years ago, which were comfy but not as much as the UM3Xs.
