My advice:
1. Sell your alo rx. You will get 350$ or more.
2. Sell your cable connecting clip+ with alo rx.
3. Sell your hfi-780 and shure iems.
You will have about 600-700$ extra.
Add the 150-300$ your going to spend on sflo2/j3/x1050/a845
So, now you got around 900$.
Add(lent or add from your budget or so) 150$
Then you got around 1000-1100$.
order JH13 for 925$ - there is a promotion till the end of July
or order a Earsonics Em3pro - thats 750Eur
Get impressions from your local audiologist and sent them the impressions.
Install rockbox on your clip.
Wait 1 month for your customs.
Result: High-end portable rig, universal for all genres, easy to carry in a small case, 70% better sounding rig over your actuall rig and actually worth the money youre going to spend.
Trust me, ive tested UM customized westone 3, universal westone 3, universal westone um3x with imod, clip+, ihp140, iphone 3g, nano 2g, nano 5g with Protector SE(not balanced, but heard that balanced make protector 80% better than in se mode, but I havent heard that) and with pico slim, with scscag lineout cables like LOD and Jack-jack. To see that im not bull shiting, see my public profile album, you can see there that ive had all that staff at the same time to test it critically.
