SE846 has been my daily commute / casual listening IEM for some time now or when I am doing grocery shopping or walking around in a mall. It never fails me as it is sturdy, and sounds pretty decent especially in the high-mids and the bass, even just with my mobile phones (iPhone 8+ and Samsung Galaxy Note 8) or the 10.5" iPad Pro (by the way, the new iPad Pros are some of the best sounding gadgets I have heard in years, probably even better than iPhone 4). I do have Layla, K10, UE18 Pro and Tia Fourte but it just happens that SE846 remains the IEM that I listen to mostly because of the convenience.
So this weekend I sat down and plugged it into the SP1000Cu. Wow. Just wow. I haven't done this until now because of my philosophy of "only the best deserves the best". I thought that although the SE846 is very good, it would not be able to demonstrate how good sounding the SP1000Cu is. Boy I was wrong. The SP1000Cu seems to be able to transcend every IEM to the next level. It may not have the soundstage or crazy separation and imaging like my Tia Fourte has, but the SE846 is definitely a star when it is connected to the SP1000Cu. Everything that sounded off when I listen to it through my mobile phones suddenly became crazily clear, smooth yet coherent. I suddenly realise that SE846, apart from Shure's electrostatic counterpart KSE1500, is still their flagship IEM - and quite rightly so. With the SP1000Cu, the SE846 can fully open its voice to its full potential - a feat finally made possible years after its debut.
