Hi, I recently purchased a set of Beyerdynamic DT 1350's (in transit) which I'm going to use for music production and portable listening. My only concern is that my J3 won't drive the 80Ω DT 1350's to their full potential. I know the J3 will be more than capable of driving them to an appropriate listening level, but from what I know this doesn't necessarily mean the headphones are being properly driven. I was thinking by adding a portable amp such as an iBasso T3 that would remove any chance of improper driving. Or is an amp unnecessary? I'd appreciate any suggestions. Thanks in advance.
