I have Etymotic MC5's, they were like $79 and I like them for the detail and even sound throughout, they are a bit thin in the low end. You might not like them John because they fit well into your ear canal for best results and they are detailed but not harsh. I have not heard the HF5's.
I was going to suggest an Ultimate Ears offering maybe UE-600, I have not heard them but I owned a pair of UE700's for awhile and just recently sold them to raise funds for something but will soon buy some UE600's myself...I like the same things you do John but I'm finding with IEM's I enjoy some nice tight bass. I have some Sony's with extra bass that are sometimes a touch too bassy and distort although some EQ works well.
I'd like to try the Hifiman ones Saisunil has one day, they will probably be the next I try after the UE600's....John if you do go ahead and buy some UE600's and do not like them I will most certainly purchase them from you and have you ship to me from Aus. its the least I could do..!!
Keep in mind these are in my opinion the hardest thing to recommend, the intimate listening thing is a lot different in terms of SQ because you can really dial in what you like once you start hearing some.....try 2 pair at $50 and pick you fav. then we can help even more....my .02
