I think part of the confusion is contributed to the facts that there are many combinations to alter the sound with the various treble and bass ports as well as the different type of tips being used. Factor in the differences caused by our unique ear structure and you'll get some head scratching results.
When I first purchased the SA7 a few months ago, I could not get a reliable fit and seal with the stock tips and treble+ ports, and I didn't have any extras tips to test out. In the rare moment when I didn't move my head and finally got the ideal seal that was needed, the SA7 reminded me of the PFE112 sound. However, the quick ownership of my first pair was probably due to work and family related stress at the time as well as the initial disappointments with the cable and having the stock tips get stuck in my ears too many times when taking the SA7 out. So, I hastefully returned it.
I just feel with iems' in general, if it calls for too much fiddling around to get a good fit and sound, it's poorly designed and executed. I'll admit, I don't take this hobby as serious as others. But, it was Shigzero's comment on how the SA7 is worth the effort has persuaded me to go round two with it and the nice discounted price, which I originally thought I got a good deal with 20% off $350.
On a side note, other than Shigzero recent review, Google did not return any results for any other impressions. I wonder if this is due to the huge gap from the marketing fiasco to the 3+ year delay, moving manufacturing operations to stateside, and ending up with a product that resembles more like the lesser model. That and the 50Cent fiasco must have made a major dent towards current and future customer loyalty. I guess Sleeks main focus and cash cow is their custom products. I have yet to see the SA7 being sold to third party retailers like the older SA6 once did.
