Hello all, I've just joined after lurking for a week or two. Found the forum after searching for headphone reviews when looking for a decent-quality set of portable over-ear cans. After reading quite a few reviews and a visit to my local Richer Sounds hifi store I got myself a lovely pair of Audio-Technica ATH-ES55s. I also have a pair of Sennheiser HD201s and an old pair of Audio Technica ATH-T3s. Very impressed with the sound of the ES55s but have a couple of questions. I've read a few threads on headphone amplifiers, and reviews on the ES55s - would the 'phones benefit at all from being amped? From what I can gather it may only give a boost to the volume - I'm on a budget so would probably be something like the Fiio E6. Would it be worth my while getting one or not? The HD201s I've heard sound better with an amp but not sure it'd be worth spending at least the same amount as they're worth on a headphone amp! I do a lot of radio listening, having a decent-quality pair of cans really shows the shortcomings of DAB broadcasting in the UK and the rubbish bitrates they use! FM's pretty good though but would I benefit even more from listening to high-quality internet streams or would the benefit be negligable? I do tend to listen quite a bit from portable devices when out walking the dog, lying in bed etc and sometimes use TuneIn with a higher bitrate stream when on wifi but not really viable when out and about due to data limits on my phone's plan. Is there a source of HD radio streams I can access? Some stations on TuneIn i'm finding that the bitrates are still too low for more serious listening.
