Hello, At the moment I am using a beginner's Harley Benton D.I. pedal with basic eq and compression. On it, the headphone output is so hiss-prone that it's pretty much unusable. Likewise if I connect it to my iMac through the D.I. or line output. Does anybody have a recommendation for something around the £150 mark to be able to, first and foremost, practice with headphones in a hiss-free condition – as much as that is possible? I started looking around and saw the Apogee Jam+ or Focusrite Scarlett interfaces, would these have better headphone outputs than a pre-amp pedal? Thank you.
