Hmm.... I also compared the JH by memory to UM models.
The Merlin's were pretty bass heavy, so if you are a purist stay clear. However the Merlins still have clear mids and good enough head stage. (Good perhaps even great but for bassheads!)
The Miracles just didn't want to fit in my ears so I couldn't try them.
The 3DD in comparison to the Merlin has a weird/wonky sounding mids and also a veil to the entire sound.
The Mage had the tonal balance I like (slight elevation in bass) however the lack of clarity in the midrange was a deal breaker for me.
I would say this to all. In my books, the JH7 sounded best to me (I'm getting them!) and followed by the Merlins (only if you don't mind extra bass, which I kinda mind) then the JH5, then UM Mage and lastly the 3DD which sounded just downright wrong to me. (Poor fit? Maybe.)
5. UM 3DD
This list excludes the Jh10/10x3/11/13/16 and UM Miracles/Aero/Marvel.
Btw, just a small tip off! Jerry is coming out with a new flagship in October!
Thanks cool post! Am attracted more toward a clear, good high sound signature like ER4s (or P) awesome indeed, but with little more bass.
Like I said, comming from W4r, for my first jump in the CIEM arena, I was tempted to go with JH5 (similar price range, tag) or go with JH13 w/ P-51 Mustang amp. and a Twag cable.
