Yes, box was sealed from agiprodj.com. Also, the date of manufacture was 1/23/14, same as Eugene's (Eugguy) who also bought his from them and has had no problems.
lol @ that last paragraph. they don't take returns on anything that touched human flesh. lmao. so basically you can't return anything to them.
Even if they did accept returns it would be $200 on a 846...
they got that covered too. see 2nd paragraph.
by the way, if you look on amazon, you'll see a not insignificant number of people complaining about defective se846s. not a majority by any means, but much higher than a 6 sigma tolerance. shure needs to fix that. it's absolutely unacceptable to have 5% or so of se846s not work.
I did a few months ago, briefly. I don't remember enough to make comparisons, but I do remember it being pretty good. I actually considered buying one after I listened to it, but wasn't a fan of the UI.
I did for a week or so before I purchased my new DAP. My memory isn't what it used to be but I don't remember any significant issues pairing with the X3. I loaned out my X3 but when I get it back later this month I will pair them again and write something up. Generally speaking I like the X3 SQ and it was a competent DAC. I routinely paired it with my W4R and ER4s IEMs and my DT990 600ohm HP.
Yup... I own those. Just fine for normal casual listening - pretty dang good pairing. I use the the X3 with my E12 when having a more serious session. Better dynamics... etc.
I'm waiting for the X5... hoping it will remove the need of the E12... for better portability.
