Hmm, strange. Maybe this was a small batch, I got.
I tried it directly from the HO. Let aside the DX50, which I like for its form factor and functionality, less for the soundquality. Amped it is good.
I also tried the UM 3X with the Sony PHA-2. Sounds ok - good. Still waiting for the Hifi ET MA9 to load up, which is still my favorite source.
So for they tend to be on the neutral side. Also the highs are rather shy, which disqualifies it to be V-shaped. They have the experience, but somwhere it was stated, that the Merlins definitely are in another league.
How are they as compared to the dt1350 and re-zero? i owned both items before, and saw them in your profile - would just give me an idea how the UM 3x are as compared to the two.
